2017-12-04arch/tile: mark as orphanedChris Metcalf1-3/+1
The chip family of TILEPro and TILE-Gx was developed by Tilera, which was eventually acquired by Mellanox. The tile architecture was added to the kernel in 2010 and first appeared in 2.6.36. Now at Mellanox we are developing new chips based on the ARM64 architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and our customers using tile architecture products are not, as far as we know, looking to upgrade to newer kernel releases. In the absence of someone in the community stepping up to take over maintainership, this commit marks the architecture as orphaned.

2017-11-17Merge tag 'clk-for-linus' of ↵Linus Torvalds1-0/+1
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have two changes to the core framework this time around. The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis.

The ext4 touches came from Jan, and the xfs touches have Darrick's reviewed-by. An xfstest for the MAP_SYNC feature has been through a few round of reviews and is on track to be merged. - Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable 'userspace flush' of persistent memory updates via filesystem-dax mappings. It arranges for any filesystem metadata updates that may be required to satisfy a write fault to also be flushed ("on disk") before the kernel returns to userspace from the fault handler. Effectively every write-fault that dirties metadata completes an fsync() before returning from the fault handler. The new MAP_SHARED_VALIDATE mapping type guarantees that the MAP_SYNC flag is validated as supported by the filesystem's ->mmap() file operation. - Add support for the standard ACPI 6.2 label access methods that replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods. This enables interoperability with environments that only implement the standardized methods. - Add support for the ACPI 6.2 NVDIMM media error injection methods. - Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for latch last shutdown status, firmware update, SMART error injection, and SMART alarm threshold control. - Cleanup physical address information disclosures to be root-only. - Fix revalidation of the DIMM "locked label area" status to support dynamic unlock of the label area. - Expand unit test infrastructure to mock the ACPI 6.2 Translate SPA (system-physical-address) command and error injection commands.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.15 kernel cycle: Core: - The pin control Kconfig entry PINCTRL is now turned into a menuconfig option. This obviously has the implication of making the subsystem menu visible in menuconfig. This is happening because of two things: (a) Intel have started to deploy and depend on pin controllers in a way that is affecting users directly. This happens on the highly integrated laptop chipsets named after geographical places: baytrail, broxton, cannonlake, cedarfork, cherryview, denverton, geminilake, lewisburg, merrifield, sunrisepoint... It started a while back and now it is ever more evident that this is crucial infrastructure for x86 laptops and not an embedded obscurity anymore. Users need to be aware. (b) Pin control expanders on I2C and SPI that are arch-agnostic. Currently Semtech SX150X and Microchip MCP28x08 but more are expected. Users will have to be able to configure these in directly for their set-up. - Just go and select GPIOLIB now that we made sure that GPIOLIB is a very vanilla subsystem. Do not depend on it, if we need it, select it. - Exposing the pin control subsystem in menuconfig uncovered a bunch of obscure bugs that are now hopefully fixed, all more or less pertaining to Blackfin. - Unified namespace for cross-calls between pin control and GPIO. - New support for clock skew/delay generic DT bindings and generic pin config options for this. - Minor documentation improvements. Various: - The Renesas SH-PFC pin controller has evolved a lot. It seems Renesas are churning out new SoCs by the minute. - A bunch of non-critical fixes for the Rockchip driver. - Improve the use of library functions instead of open coding. - Support the MCP28018 variant in the MCP28x08 driver. - Static constifying" * tag 'pinctrl-v4.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (91 commits) pinctrl: gemini: Fix missing pad descriptions pinctrl: Add some depends on HAS_IOMEM pinctrl: samsung/s3c24xx: add CONFIG_OF dependency pinctrl: gemini: Fix GMAC groups pinctrl: qcom: spmi-gpio: Add pmi8994 gpio support pinctrl: ti-iodelay: remove redundant unused variable dev pinctrl: max77620: Use common error handling code in max77620_pinconf_set() pinctrl: gemini: Implement clock skew/delay config pinctrl: gemini: Use generic DT parser pinctrl: Add skew-delay pin config and bindings pinctrl: armada-37xx: Add edge both type gpio irq support pinctrl: uniphier: remove eMMC hardware reset pin-mux pinctrl: rockchip: Add iomux-route switching support for rk3288 pinctrl: intel: Add Intel Cedar Fork PCH pin controller support pinctrl: intel: Make offset to interrupt status register configurable pinctrl: sunxi: Enforce the strict mode by default pinctrl: sunxi: Disable strict mode for old pinctrl drivers pinctrl: sunxi: Introduce the strict flag pinctrl: sh-pfc: Save/restore registers for PSCI system suspend pinctrl: sh-pfc: r8a7796: Use generic IOCTRL register description ...

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma updates from Doug Ledford: "This is a fairly plain pull request. Lots of driver updates across the stack, a huge number of static analysis cleanups including a close to 50 patch series from Bart Van Assche, and a number of new features inside the stack such as general CQ moderation support. Nothing really stands out, but there might be a few conflicts as you take things in. In particular, the cleanups touched some of the same lines as the new timer_setup changes. Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday. So there is a larger number of patches processed in that timeframe than I was striving for.

git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux Pull RISC-V architecture support from Palmer Dabbelt: "This contains the core RISC-V Linux port, which has been through nine rounds of review on various mailing lists. The port is not complete: there's some cleanup patches moving through the review process, a whole bunch of drivers that need some work, and a lot of feature additions that will be needed. The patches contained in this tag have been through nine rounds of review on the various mailing lists. I have some outstanding cleanup patches, but since there's been so much review on these patches I thought it would be best to submit them as-is and then submit explicit cleanup patches so everyone can review them. This first patch set is big enough that it's a bit of a pain to constantly rewrite, and it's caused a few headaches with various contributors. The port is definately a work in progress. While what's there builds and boots with 4.14, it's a bit hard to actually see anything happen because there are no device drivers yet. I maintain a staging branch that contains all the device drivers and cleanup that actually works, but those patches won't all be ready for a while. I'd like to get what we currently have into your tree so everyone can start working from a single base -- of particular importance is allowing the glibc upstreaming process to proceed so we can sort out any possibly lingering user-visible ABI problems we might have. Copied below is the ChangeLog that contains the history of this patch set: (v9) As per suggestions on our v8 patch set, I've split the core architecture code out from our drivers and would like to submit this patch set to be included into linux-next, with the goal being to be merged in during the next merge window. This patch set is based on 4.14-rc2, but if it's better to have it based on something else then I can change it around. This patch set contains just the core arch code for RISC-V, so while it builds an nominally boots, you can't print or take an interrupt so it's not that useful. If you're looking to actually boot a system it would probably be better to use the full patch set listed below. We've collected a handful of tags from reviewers, and the remainder of the patch set only got minimal feedback last time. Here's what changed: - We now use the device tree to initialize the timer driver so it's less tighly coupled with the arch port. - I cleaned up the defconfigs -- there's actually now just one, and it's empty. For now I think we're OK with what the kernel sets as defaults, but I anticipate we'll begin to expand this as people start to use the port more. - The VDSO symbols version is sane. - We WFI while spinning in the boot loop. - A handful of comments have been added. While there are still a handful of FIXMEs in this patch set, we've started to get enough interest from various users and contributors that maintaining an out of tree patch set is starting to become a big burden. Hopefully the patches are good enough to merge now, which will at least get everyone working in a more reasonable manner as we clean up the remaining issues. (v8) I know it may not be the ideal time to submit a patch set right now, as it's the middle of the merge window, but things have calmed down quite a bit in the last month so I thought it would be good to get everyone on the same page. There's been a handful of changes since the last patch set, but most of them are fairly minor: - We changed PAGE_OFFSET to allowing mapping more physical memory on 64-bit systems. This is user configurable, as it triggers a different code model that generates slightly less efficient code. - The device tree binding documentation is back, I'd managed to lose it at some point. - We now pass the atomic64 test suite - The SBI timer driver has been refactored. (v7) It's been a while since my last patch set, but the changes han been fairly minimal: - The PCI cleanup patches have been dropped, we'll do them as a separate patch set later. - We've the Kconfig entries from CONFIG_ISA_* to CONFIG_RISCV_ISA_*, to make grep easier. - There have been a handful of memory model related tweaks in I/O land, particularly relating the PCI and the upcoming platform specification. There are significant comments in the relevant files. This is still a WIP, but I think we're close to getting as good as we're going to get until we end up with some more specifications. (v6) As it's been only a day since the v5 patch set, the changes are pretty minimal: - The patch set is now based on linux-next/master, which I believe is a better base now that we're getting closer to upstream. - EARLY_PRINTK is no longer an option. Since the SBI console is reasonable, there's no penalty to enabling it (and thus no benefit to disabling it). - The mmap syscalls were refactored a bit. (v5) Things have really started to calm down, so this is fairly similar to the v4 patch set. The most interesting changes include: - We've moved back to a single patch set. - SMP support has been fixed, I was accidentally running on a non-SMP configuration. There were various mistakes all over the tree as a result of this. - The cmpxchg syscalls have been removed, as they were deemed a bad idea. As a result, RISC-V Linux systems mandate the A extension. The corresponding Kconfig entry to enable builds on non-A systems has been removed. - A few more atomic fixes: mostly fence changes, but those resulted in a handful of additional macros that were no longer necessary. - riscv_early_sie has been removed. (v4) There have only been a few changes since the v3 patch set: - The cmpxchg64 syscall is no longer enabled on 32-bit systems. It's not possible to provide this on SMP systems, and it's not necessary as glibc knows not to call it. - We provide a ELF_HWCAP so users can determine the ISA of the machine the kernel is running on. - The multi-line comments are in a better form. - There were a handful of headers that could be replaced with the asm-generic versions, and a few unnecessary definitions. - We no longer use printk, but instead use pr_*. - A few Kconfig and defconfig entries have been cleaned up. (v3) A highlight of the changes since the v2 patch set includes: - We've split out all our drivers into separate patch sets, which I've already sent out to the relevant maintainers. I haven't included those patches in this patch set, but some of them are necessary to build our port. - The patch set is now split up differently: rather than being split per directory it is split per topic. Hopefully this will make it easier to review the port on the mailing list. The split is a bit rough, so you probably still want to look at the patch set as a whole. - atomic.h has been completely rewritten and is hopefully now correct. I've attempted to sanitize the various other memory model related code as well, and I think it should all be sane now aside from a handful of FIXMEs commented in the code. - We've changed the cmpexchg syscall to always exist and to not be multiplexed. There is also a VDSO entry for compare and exchange, which allows kernels with the A extension to execute user code without the A extension reasonably fast. - Our user-visible register state now contains enough space for the Q extension for 128-bit floating point, as well as a few words to allow extensibility to future ISA extensions like the eventual V extension for vectors. - A handful of driver cleanups, but these have been split into separate patch sets now so I won't duplicate them here. (v2) A highlight of the changes since the v1 patch set includes: - We've split out our drivers into the right places, which means now there's a lot more patches. I'll be submitting these patches to various subsystem maintainers and including them in any future RISC-V patch sets until they've been merged. - The SBI console driver has been completely rewritten to use the HVC helpers and is now significantly smaller. - We've begun to use weaker barriers as opposed to just the big "fence". There's still some work to do here, specifically: - We need fences in the relaxed MMIO functions. - The non-relaxed MMIO functions are missing R/W bits on their fences. - Many AMOs need the aq and rl bits set. - We now have thread_info in task_struct. As a result, sscratch now contains TP instead of SP. This was necessary because thread_info is no longer on the stack. - A few shared routines have been added that we use instead of creating another arch copy" Reviewed-by: Arnd Bergmann <arnd@arndb.de> * tag 'riscv-for-linus-4.15-arch-v9-premerge' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux: RISC-V: Build Infrastructure RISC-V: User-facing API RISC-V: Paging and MMU RISC-V: Device, timer, IRQs, and the SBI RISC-V: Task implementation RISC-V: ELF and module implementation RISC-V: Generic library routines and assembly RISC-V: Atomic and Locking Code RISC-V: Init and Halt Code dt-bindings: RISC-V CPU Bindings lib: Add shared copies of some GCC library routines MAINTAINERS: Add RISC-V

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There are no big surprising changes in this cycle, yet not too boring, either. The biggest change from diffstat POV is the removal of the legacy OSS driver codes that have been already disabled for a long time. This will bring a few trivial merge conflicts. As new features in ASoC side, there are two things: a new AC97 bus implementation and AMD Stony platform support. Both include the relevant changes shared with other subsystems, e.g. AC97 MFD changes and DRM AMD changes. Some other highlighted topics are: - A bunch of USB-audio drivers got the hardening against the malicious device accesses with a new helper code for endpoint sanity check - Lots of cleanups for ASoC Intel platform code, including support for their open source audio firmware - Continued ASoC core componentization works - Support for scaling MCLK with sample rate in ASoC simple-card - Stabler PCM hot-unplug capability, especially for ASoC usages" * tag 'sound-4.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (302 commits) Documentation: sound: hd-audio: notes.rst ASoC: bcm2835: Support left/right justified and DSP modes ASoC: bcm2835: Enforce full symmetry ASoC: bcm2835: Support additional samplerates up to 384kHz ASoC: bcm2835: Add support for TDM modes ASoC: add mclk-fs support to audio graph card ASoC: add mclk-fs to audio graph card binding ASoC: rt5514: work around link error ASoC: rt5514: mark PM functions as __maybe_unused ASoC: rt5663: Check the JD status in the button pushing ASoC: amd: Modified DMA transfer Mechanism for Playback ASoC: rt5645: Wait for 400msec before concluding on value of RT5645_VENDOR_ID2 ASoC: sun4i-codec: fixed 32bit audio capture support for H3/H2+ ASoC: da7213: add support for DSP modes ASoC: sun8i-codec: Add a comment on the LRCK inversion ASoC: sun8i-codec: Set the BCLK divider ASoC: rt5663: Delay and retry reading rt5663 ID register ASoC: amd: use do_div rather than 64 bit division to fix 32 bit builds ASoC: cs42l56: Fix reset GPIO name in example DT binding ASoC: rt5514-spi: check irq status to schedule data copy in resume function ...

They all have proper acks, caused no merge conflicts in linux-next where they have been for a while. They are namely: - to-gpiod conversion of the i2c-gpio driver and its users (touching arch/* and drivers/mfd/*) - adding a sbs-manager based on I2C core updates to SMBus alerts (touching drivers/power/*) Other notable changes: - i2c_boardinfo can now carry a dev_name to be used when the device is created. This is because some devices in ACPI world need fixed names to find the regulators. - the designware driver got a long discussed overhaul of its PM handling. img-scb and davinci got PM support, too. - at24 driver has way better OF support.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.15 kernel cycle: Core: - Fix the semantics of raw GPIO to actually be raw. No inversion semantics as before, but also no open draining, and allow the raw operations to affect lines used for interrupts as the caller supposedly knows what they are doing if they are getting the big hammer. - Rewrote the __inner_function() notation calls to names that make more sense. I just find this kind of code disturbing. - Drop the .irq_base() field from the gpiochip since now all IRQs are mapped dynamically. This is nice. - Support for .get_multiple() in the core driver API. This allows us to read several GPIO lines with a single register read. This has high value for some usecases: it can be used to create oscilloscopes and signal analyzers and other things that rely on reading several lines at exactly the same instant. Also a generally nice optimization. This uses the new assign_bit() macro from the bitops lib that was ACKed by Andrew Morton and is implemented for two drivers, one of them being the generic MMIO driver so everyone using that will be able to benefit from this. - Do not allow requests of Open Drain and Open Source setting of a GPIO line simultaneously. If the hardware actually supports enabling both at the same time the electrical result would be disastrous. - A new interrupt chip core helper. This will be helpful to deal with "banked" GPIOs, which means GPIO controllers with several logical blocks of GPIO inside them. This is several gpiochips per device in the device model, in contrast to the case when there is a 1-to-1 relationship between a device and a gpiochip. New drivers: - Maxim MAX3191x industrial serializer, a very interesting piece of professional I/O hardware. - Uniphier GPIO driver. This is the GPIO block from the recent Socionext (ex Fujitsu and Panasonic) platform. - Tegra 186 driver. This is based on the new banked GPIO infrastructure. Other improvements: - Some documentation improvements. - Wakeup support for the DesignWare DWAPB GPIO controller. - Reset line support on the DesignWare DWAPB GPIO controller. - Several non-critical bug fixes and improvements for the Broadcom BRCMSTB driver. - Misc non-critical bug fixes like exotic errorpaths, removal of dead code etc. - Explicit comments on fall-through switch() statements" * tag 'gpio-v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (65 commits) gpio: tegra186: Remove tegra186_gpio_lock_class gpio: rcar: Add r8a77995 (R-Car D3) support pinctrl: bcm2835: Fix some merge fallout gpio: Fix undefined lock_dep_class gpio: Automatically add lockdep keys gpio: Introduce struct gpio_irq_chip.first gpio: Disambiguate struct gpio_irq_chip.nested gpio: Add Tegra186 support gpio: Export gpiochip_irq_{map,unmap}() gpio: Implement tighter IRQ chip integration gpio: Move lock_key into struct gpio_irq_chip gpio: Move irq_valid_mask into struct gpio_irq_chip gpio: Move irq_nested into struct gpio_irq_chip gpio: Move irq_chained_parent to struct gpio_irq_chip gpio: Move irq_default_type to struct gpio_irq_chip gpio: Move irq_handler to struct gpio_irq_chip gpio: Move irqdomain into struct gpio_irq_chip gpio: Move irqchip into struct gpio_irq_chip gpio: Introduce struct gpio_irq_chip pinctrl: armada-37xx: remove unused variable ...
