git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver changes from Olof Johansson: "A handful of driver-related changes. We've had a bunch of them going in through other branches as well, so it's only a part of what we really have this release. Larger pieces are: - Removal of a now unused PWM driver for atmel [ This includes AVR32 changes that have been appropriately acked ] - Performance counter support for the arm CCN interconnect - OMAP mailbox driver cleanups and consolidation - PCI and SATA PHY drivers for SPEAr 13xx platforms - Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to better model regulators/power" Note: this merge also fixes up the semantic conflict with the new calling convention for devm_phy_create(), see commit f0ed817638b5 ("phy: core: Let node ptr of PHY point to PHY and not of PHY provider") that came in through Greg's USB tree.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Olof Johansson: "This merge window brings a good size of cleanups on various platforms. Among the bigger ones: - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer and time updates from Thomas Gleixner: "A rather large update of timers, timekeeping & co - Core timekeeping code is year-2038 safe now for 32bit machines. Now we just need to fix all in kernel users and the gazillion of user space interfaces which rely on timespec/timeval :) - Better cache layout for the timekeeping internal data structures. - Proper nanosecond based interfaces for in kernel users. - Tree wide cleanup of code which wants nanoseconds but does hoops and loops to convert back and forth from timespecs. Some of it definitely belongs into the ugly code museum. - Consolidation of the timekeeping interface zoo. - A fast NMI safe accessor to clock monotonic for tracing. This is a long standing request to support correlated user/kernel space traces. With proper NTP frequency correction it's also suitable for correlation of traces accross separate machines. - Checkpoint/restart support for timerfd. - A few NOHZ[_FULL] improvements in the [hr]timer code. - Code move from kernel to kernel/time of all time* related code. - New clocksource/event drivers from the ARM universe. I'm really impressed that despite an architected timer in the newer chips SoC manufacturers insist on inventing new and differently broken SoC specific timers. [ Ed. "Impressed"? I don't think that word means what you think it means ] - Another round of code move from arch to drivers.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/cleanup Merge "ARM: tegra: move fuse code out of arch/arm" from Thierry Reding: This branch moves code related to the Tegra fuses out of arch/arm and into a centralized location which could be shared with ARM64. It also adds support for reading the fuse data through sysfs. Included is also some preparatory work that moves Tegra-related header files from include/linux to include/soc/tegra as suggested by Arnd. Furthermore the Tegra chip ID is now retrieved using a function rather than a variable so that sanity checks can be done. This is convenient in subsequent patches that will move some of the code that's currently called from Tegra machine setup into regular initcalls so that it can be reused on 64-bit ARM. The sanity checks help with verifying that no code tries to obtain the Tegra chip ID before the underlying driver is properly initialized. * tag 'tegra-for-3.17-fuse-move' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra Signed-off-by: Olof Johansson <olof@lixom.net>

2014-07-17mei: don't schedule suspend in pm idleAlexander Usyskin2-2/+2
Calling pm_schedule_suspend from the runtime pm idle callback may reschedule existing timer, thus in case of frequent runtime rpm idle call the suspend maybe starved. Instead we call pm_runtime_autosuspend which is checking if the timer is already charged. An example is monitoring device pci config space. Pci config sysfs handlers calls pci_config_pm_runtime_put/get helpers which in turns calls to device idle callback Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This MIC virtual bus driver takes the responsibility of creating all the virtual devices connected to the PCIe device on the host and the platform device on the card. The MIC bus hardware operations provide a way to abstract certain hardware details from the base physical devices. Examples of devices added on the MIC virtual bus include host DMA and card DMA.

2014-07-09misc/GenWQE: fix pci_enable_msi usageSebastian Ott2-7/+7
GenWQE used to call pci_enable_msi_block to allocate a desired number of MSI's. If that was not possible pci_enable_msi_block returned with a smaller number which might be possible to allocate. GenWQE then called pci_enable_msi_block with that number. Since commit a30d0108b "GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()" pci_enable_msi_exact is used which fails if the desired number of MSI's was not possible to allocate. Change GenWQE to use pci_enable_msi_range to restore the old behavior.

2014-07-09GenWQE: Improve hardware error recoveryKleber Sacilotto de Souza1-0/+45
Currently, in the event of a fatal hardware error, the driver tries a recovery procedure that calls pci_reset_function() to reset the card. This is not sufficient in some cases, needing a fundamental reset to bring the card back. This patch implements a call to the platform fundamental reset procedure on the error recovery path if GENWQE_PLATFORM_ERROR_RECOVERY is enabled. This is implemented by default only on PPC64, since this can cause problems on other archs, e.g. zSeries, where the platform has its own recovery procedures, leading to a potencial race conditition. For these cases, the recovery is kept as it was before.

2014-07-09GenWQE: Add support for EEH error recoveryKleber Sacilotto de Souza7-18/+115
This patch implements the callbacks and functions necessary to have EEH recovery support. It adds a config option to enable or disable explicit calls to trigger platform specific mechanisms on error recovery paths. This option is enabled by default only on PPC64 systems and can be overritten via debugfs. If this option is enabled, on the error recovery path the driver will call pci_channel_offline() to check for error condition and issue non-raw MMIO reads to trigger early EEH detection in case of hardware failures. This is necessary since the driver MMIO helper funtions use raw accessors.

AT91 symbols AT91SAM9263, AT91SAM9RL, and AT91SAM9G45 do not exist and this patch changes them to their correct ARCH_* version. These symbols are chosen instead of the SOC_* ones because this driver is not converted to DT. Anyway, the ATMEL_PWM symbol and the associated driver will be removed soon, during the move to the PWM sub-system.
