git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This time it looks like a quieter release cycle in the clk tree. I guess that's because of summer time holidays/vacations. The biggest change in the diffstat is in the Qualcomm clk driver, where they got support for CPUs and handful of SoCs. After that, the at91 driver got a major rewrite for newer DT bindings that should make things easier going forward and the TI code moved to a clockdomain based design. The long tail is mostly small driver updates for newer clks and some simpler SoC clock drivers such as the Hisilicon and imx support. In the core framework, we only have two small changes this time. One is a new clk API to get all clks for a device with the bulk clk APIs. This allows drivers that don't care about doing anything besides turning on all the clks to just clk_get() them all and turn them on. The other change is the beginning of a way to support save and restore of clk settings in the clk framework. TI is the only user right now, but we will want to expand upon this design in the future to support more save and restore of clk registers. At least this gets us started and works well enough for one SoC, but there's more work in the future. Core: - clk_bulk_get_all() API and friends to get all the clks for a device - Basic clk state save/restore hooks New Drivers: - Renesas RZ/A2 (R7S9210) SoC, including early clocks - Rensas RZ/G1N (R8A7744) and RZ/G2E (R8A774C0) SoCs - Rensas RZ/G2M (r8a774a1) SoC - Qualcomm Krait CPU clk support - Qualcomm QCS404 GCC support - Qualcomm SDM660 GCC support - Qualcomm SDM845 camera clock controller - Ingenic jz4725b CGU - Hisilicon 3670 SoC support - TI SCI clks on K3 SoCs - iMX6 MMDC clks - Reset Controller (RMU) support for Actions Semi Owl S900 and S700 SoCs Updates: - Rework at91 PMC clock driver for new DT bindings - Nvidia Tegra clk driver MBIST workaround fix - S2RAM support for Marvell mvebu periph clks - Use updated printk format for OF node names - Fix TI code to only search DT subnodes - Various static analysis finds - Tag various drivers with SPDX license tags - Support dynamic frequency switching (DFS) on qcom SDM845 GCC - Only use s2mps11 dt-binding defines instead of redefining them in the driver - Add some more missing clks to qcom MSM8996 GCC - Quad SPI clks on qcom SDM845 - Add support for CMT timer clocks on R-Car V3H - Add support for SHDI and various timer clocks on R-Car V3M - Improve OSC and RCLK (watchdog) handling on R-Car Gen3 SoCs - Amlogic clk-pll driver improvements and updates - Amlogic axg audio controller system clocks - Register Amlogic meson8b clock controller early - Add support for SATA and Fine Display Processor (FDP) clocks on R-Car M3-N - Consolidation of system suspend related code in Exynos, S5P, S3C SoC clk drivers - Fixes for system suspend support on Exynos542x (Odroid boards) and Exynos5433 SoC - Remove obsoleted Exynos4212 ISP clock definitions - Migrated TI am3/4/5 and dra7 SoCs to clockdomain based design - TI RTC+DDR sleep mode support for clock save/restore - Allwinner A64 display engine support and fixes - Allwinner A83t display engine support and fixes" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (186 commits) clk: qcom: Remove unused arrays in SDM845 GCC clk: fixed-rate: fix of_node_get-put imbalance clk: s2mps11: Add used attribute to s2mps11_dt_match clk: qcom: gcc-sdm660: Add MODULE_LICENSE clk: qcom: Add safe switch hook for krait mux clocks dt-bindings: clock: Document qcom,krait-cc clk: qcom: Add Krait clock controller driver dt-bindings: arm: Document qcom,kpss-gcc clk: qcom: Add KPSS ACC/GCC driver clk: qcom: Add support for Krait clocks clk: qcom: Add IPQ806X's HFPLLs clk: qcom: Add MSM8960/APQ8064's HFPLLs dt-bindings: clock: Document qcom,hfpll clk: qcom: Add HFPLL driver clk: qcom: Add support for High-Frequency PLLs (HFPLLs) ARM: Add Krait L2 register accessor functions clk: imx6q: add mmdc0 ipg clock clk: imx6sl: add mmdc ipg clocks clk: imx6sll: add mmdc1 ipg clock clk: imx6sx: add mmdc1 ipg clock ...

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull new experimental media request API from Mauro Carvalho Chehab: "A new media request API This API is needed to support device drivers that can dynamically change their parameters for each new frame. The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "The most noteworthy SoC driver changes this time include: - The TEE subsystem gains an in-kernel interface to access the TEE from device drivers. - The reset controller subsystem gains a driver for the Qualcomm Snapdragon 845 Power Domain Controller. - The Xilinx Zynq platform now has a firmware interface for its platform management unit. This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree updates from Arnd Bergmann: "There are close to 800 indivudal changesets in this branch again, which feels like a lot. There are particularly many changes for the NVIDIA Tegra platform this time, in fact more than it has seen in the two years since the v4.9 merge window. Aside from this, it's been fairly normal, with lots of changes going into Renesas R-CAR, NXP i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP. Most of the changes are for adding new features into existing boards, for brevity I'm only mentioning completely new machines and SoCs here. For the first time I think we have (slightly) more new 64-bit hardware than 32-bit: Two boards get added for TI OMAP: Moxa UC-2101 is an industrial computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a minor variation of the motherboards of the GTA04 phone, see https://shop.goldelico.com/wiki.php?page=GTA04A5 Clearfog is a nice little board for quad-core Marvell Armada 8040 network processor, see https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/ Two additional server boards come with the Aspeed baseboard management controllers: Stardragon4800 is an arm64 reference platform made by HXT (based on Qualcomm's server chips), and TiogaPass is an Open Compute mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the BMC. NXP i.MX usually sees a lot of new boards each release. This time there we only add one minor variant: ConnectCore 6UL SBC Pro uses the same SoM design as the ConnectCore 6UL SBC Express added later. However, there is a new chip, the i.MX6ULZ, which is an even smaller variant of the i.MX6ULL, with features removed. There is also support for the reference board design, the i.MX6ULZ 14x14 EVK. A new Raspberry Pi variant gets added, this one is the CM3 compute module based on bcm2837, it was launched in early 2017 but only now added to the kernel, both as 32-bit and as 64-bit files, as we tend to do for Raspberry Pi. On the Allwinner side, everything is again about cheap development boards, usually of the "Fruit Pi" variety. The new ones this time are: - Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/ - Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/ - Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts - Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html The last one of these is now a 64-bit version of the earlier Banana Pi M2+ H3, with the same board layout. Similarly, for Rockchips, get get another variant of the 32-bit Asus Tinker board, the model 'S' based on rk3288, and three now boards based on the popular RK3399 chip: - ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/ - Rock960: https://www.96boards.org/product/rock960/ - RockPro64: https://www.pine64.org/?page_id=61454 These are all quite powerful boards with lots of RAM and I/O, and the RK3399 is the same chip used in several Chromebooks. Finally, we get support for the PX30 (aka rk3326) chip, which is based on the low-end 64-bit Cortex-A35 CPU core. So far, only the evaluation board is supported. One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is based on the MT7622 WiFi router platform, and the first product I've seen with a 64-bit Mediatek chip in that market: http://www.banana-pi.org/r64.html For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370 development board, which are similar to the Hi3660 and Hikey 360 respectively, but add support for an NPU. Amlogic gets initial support for the Meson-G12A chip (S905D2), another quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit side, we gain support for an actual end-user product, the Endless Computers Endless Mini based on Meson8b (S805), see https://endlessos.com/computers/ Qualcomm adds support for their MSM8998 SoC and evaluation platform. This chip is commonly known as the Snapdragon 835, and is used in high-end phones as well as low-end laptops. For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added, but no boards for this one. However, we do add boards for the previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the M3NULCB Starter Kit Pro. While we have lots of DT changes for NVIDIA to update the existing files, the only board that gets added is the Toradex Colibri T20 on Colibri Evaluation Board for the old Tegra2. Synaptics add support for their AS370 SoC, which is part of the (formerly Marvell) Berlin line of set-top-box chips used e.g. in the various Google Chromecast.

2018-10-29dt-bindings: drm/panel: simple: Innolux TV123WAM is actually P120ZDG-BF1Douglas Anderson1-3/+5
As far as I can tell the bindings that were added in commit 9c04400f7ea6 ("dt-bindings: drm/panel: Document Innolux TV123WAM panel bindings") weren't actually for Innolux TV123WAM but were actually for Innolux P120ZDG-BF1. As far as I can tell the Innolux TV123WAM isn't a real panel and but it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1. Let's unmosh. Here's my evidence: * Searching for TV123WAM on the Internet turns up a TI panel. While it's possible that an Innolux panel has the same model number as the TI Panel, it seems a little doubtful. Looking up the datasheet from the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm. * As far as I know, the patch adding the Innolux Panel was supposed to be for the board that's sitting in front of me as I type this (support for that board is not yet upstream). On the back of that panel I see Innolux P120ZDZ-EZ1 rev B1. * Someone pointed me at a datasheet that's supposed to be for the panel in front of me (sorry, I can't share the datasheet). That datasheet has the string "p120zdg-bf1" * If I search for "P120ZDG-BF1" on the Internet I get hits for panels that are 2160x1440. They don't have datasheets, but the fact that the resolution matches is a good sign. While we doing the rename, also mention that no-hpd can be used with this panel. See the previous patch in this series ("drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM").

2018-10-29dt-bindings: drm/panel: simple: Add no-hpd propertyDouglas Anderson1-0/+3
Some eDP panels that are designed to be always connected to a board use their HPD signal to signal that they've finished powering on and they're ready to be talked to. However, for various reasons it's possible that the HPD signal from the panel isn't actually hooked up. In the case where the HPD isn't hooked up you can look at the timing diagram on the panel datasheet and insert a delay for the maximum amount of time that the HPD might take to come up. Let's add a property in the device tree for this concept.

"LTP, Lmbench ..." will be tested for every commit. See here for more details: https://gitlab.com/c-sky/buildroot/pipelines We'll continouslly improve csky subsystem in future" Arnd acks, and adds the following notes: "I did a thorough review of the ABI, which as usual mainly consists of spotting any files that don't use the asm-generic ABI itself, and having it changed to it matches exactly what we do on other new architectures. I also looked at every other patch and commented on maybe half of them where I saw something that did not quite seem right. Others have reviewed specific patches in greater depth. I'm sure that one could fine more of the minor details, but as long as they are not ABI relevant, they can be fixed later. The only patch that is part of the ABI and that nobody reviewed is the signal handling. This is one of the areas I never worked on in much detail. I did not see anything wrong with it, but I also don't know what the problems with the other architectures are here, and we seem to be hitting issues occasionally, and we never managed to generalize this enough for new architectures to have a trivial implementation. I was originally hoping that we could have the 64-bit time_t interfaces ready in time to completely drop the 32-bit ones, but that did not happen. We might still remove them in the next merge window depending on whether the libc upstream people prefer to keep them or not. One more general comment: I think this may well be the last new CPU architecture we ever add to the kernel. Both nds32 and c-sky are made by companies that also work on risc-v, and generally speaking risc-v seems to be killing off any of the minor licensable instruction set projects, just like ARM has mostly killed off the custom vendor-specific instruction sets already. If we add another architecture in the future, it may instead be something like the LLVM bitcode or WebAssembly, who knows?"

git://git.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 v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver" * tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (116 commits) gpio: Clarify kerneldoc on gpiochip_set_chained_irqchip() gpio: Remove unused 'irqchip' argument to gpiochip_set_cascaded_irqchip() gpio: Drop parent irq assignment during cascade setup mmc: pwrseq_simple: Fix incorrect handling of GPIO bitmap gpio: fix SNPS_CREG kconfig dependency warning gpiolib: Initialize gdev field before is used gpio: fix kernel-doc after devres.c file rename gpio: fix doc string for devm_gpiochip_add_data() to not talk about irq_chip gpio: syscon: Fix possible NULL ptr usage gpiolib: Show correct direction from the beginning pinctrl: msm: Use init_valid_mask exported function gpiolib: Add init_valid_mask exported function GPIO: add single-register GPIO via CREG driver dt-bindings: Document the Synopsys GPIO via CREG bindings gpio: mockup: use device properties instead of platform_data gpio: Slightly more helpful debugfs gpio: omap: Remove set but not used variable 'dev' gpio: omap: drop omap_gpio_list Accept partial 'gpio-line-names' property. gpio: omap: get rid of the conditional PM runtime calls ...
