2014-12-09Merge tag 'drivers-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree. The largest single change here this time around is the Tegra iommu/memory controller driver, which gets updated to the new iommu DT binding. More drivers like this are likely to follow for the following merge window, but we should be able to do those through the iommu maintainer. Other notable changes are: - reset controller drivers from the reset maintainer (socfpga, sti, berlin) - fixes for the keystone navigator driver merged last time - at91 rtc driver changes related to the at91 cleanups - ARM perf driver changes from Will Deacon - updates for the brcmstb_gisb driver" * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (53 commits) clocksource: arch_timer: Allow the device tree to specify uninitialized timer registers clocksource: arch_timer: Fix code to use physical timers when requested memory: Add NVIDIA Tegra memory controller support bus: brcmstb_gisb: Add register offset tables for older chips bus: brcmstb_gisb: Look up register offsets in a table bus: brcmstb_gisb: Introduce wrapper functions for MMIO accesses bus: brcmstb_gisb: Make the driver buildable on MIPS of: Add NVIDIA Tegra memory controller binding ARM: tegra: Move AHB Kconfig to drivers/amba amba: Add Kconfig file clk: tegra: Implement memory-controller clock serial: samsung: Fix serial config dependencies for exynos7 bus: brcmstb_gisb: resolve section mismatch ARM: common: edma: edma_pm_resume may be unused ARM: common: edma: add suspend resume hook powerpc/iommu: Rename iommu_[un]map_sg functions rtc: at91sam9: add DT bindings documentation rtc: at91sam9: use clk API instead of relying on AT91_SLOW_CLOCK ARM: at91: add clk_lookup entry for RTT devices rtc: at91sam9: rework the Kconfig description ...

2014-12-08Merge tag 'dm-3.19-changes' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Significant DM thin-provisioning performance improvements to meet performance requirements that were requested by the Gluster distributed filesystem. Specifically, dm-thinp now takes care to aggregate IO that will be issued to the same thinp block before issuing IO to the underlying devices. This really helps improve performance on HW RAID6 devices that have a writeback cache because it avoids RMW in the HW RAID controller. - Some stable fixes: fix leak in DM bufio if integrity profiles were enabled, use memzero_explicit in DM crypt to avoid any potential for information leak, and a DM cache fix to properly mark a cache block dirty if it was promoted to the cache via the overwrite optimization. - A few simple DM persistent data library fixes - DM cache multiqueue policy block promotion improvements. - DM cache discard improvements that take advantage of range (multiblock) discard support in the DM bio-prison. This allows for much more efficient bulk discard processing (e.g. when mkfs.xfs discards the entire device). - Some small optimizations in DM core and RCU deference cleanups - DM core changes to suspend/resume code to introduce the new internal suspend/resume interface that the DM thin-pool target now uses to suspend/resume active thin devices when the thin-pool must suspend/resume. This avoids forcing userspace to track all active thin volumes in a thin-pool when the thin-pool is suspended for the purposes of metadata or data space resize. * tag 'dm-3.19-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (49 commits) dm crypt: use memzero_explicit for on-stack buffer dm space map metadata: fix sm_bootstrap_get_count() dm space map metadata: fix sm_bootstrap_get_nr_blocks() dm bufio: fix memleak when using a dm_buffer's inline bio dm cache: fix spurious cell_defer when dealing with partial block at end of device dm cache: dirty flag was mistakenly being cleared when promoting via overwrite dm cache: only use overwrite optimisation for promotion when in writeback mode dm cache: discard block size must be a multiple of cache block size dm cache: fix a harmless race when working out if a block is discarded dm cache: when reloading a discard bitset allow for a different discard block size dm cache: fix some issues with the new discard range support dm array: if resizing the array is a noop set the new root to the old one dm: use rcu_dereference_protected instead of rcu_dereference dm thin: fix pool_io_hints to avoid looking at max_hw_sectors dm thin: suspend/resume active thin devices when reloading thin-pool dm: enhance internal suspend and resume interface dm thin: do not allow thin device activation while pool is suspended dm: add presuspend_undo hook to target_type dm: return earlier from dm_blk_ioctl if target doesn't implement .ioctl dm thin: remove stale 'trim' message in block comment above pool_message ...

2014-12-04clocksource: arch_timer: Allow the device tree to specify uninitialized ↵Doug Anderson
timer registers Some 32-bit (ARMv7) systems are architected like this: * The firmware doesn't know and doesn't care about hypervisor mode and we don't want to add the complexity of hypervisor there. * The firmware isn't involved in SMP bringup or resume. * The ARCH timer come up with an uninitialized offset (CNTVOFF) between the virtual and physical counters. Each core gets a different random offset. * The device boots in "Secure SVC" mode. * Nothing has touched the reset value of CNTHCTL.PL1PCEN or CNTHCTL.PL1PCTEN (both default to 1 at reset) On systems like the above, it doesn't make sense to use the virtual counter. There's nobody managing the offset and each time a core goes down and comes back up it will get reinitialized to some other random value. This adds an optional property which can inform the kernel of this situation, and firmware is free to remove the property if it is going to initialize the CNTVOFF registers when each CPU comes out of reset. Currently, the best course of action in this case is to use the physical timer, which is why it is important that CNTHCTL hasn't been changed from its reset value and it's a reasonable assumption given that the firmware has never entered HYP mode. Note that it's been said that on ARMv8 systems the firmware and kernel really can't be architected as described above. That means using the physical timer like this really only makes sense for ARMv7 systems.

2014-12-01of: Rename "poweroff-source" property to "system-power-controller"Romain Perier
It reverts commit a4b4e0461ec5 ("of: Add standard property for poweroff capability"). As discussed on the mailing list, it makes more sense to rename back to the old established property name, without the vendor prefix. Problem being that the word "source" usually tends to be used for inputs and that is out of control of the OS. The poweroff capability is an output which simply turns the system-power off. Also, this property might be used by drivers which power-off the system and power back on subsequent RTC alarms. This seems to suggest to remove "poweroff" from the property name and to choose "system-power-controller" as the more generic name. This patchs adds the required renaming changes and defines an helper function which checks if this property is set.

2014-11-30bus: mvebu-mbus: suspend/resume supportThomas Petazzoni
This commit extends the mvebu-mbus driver to provide suspend/resume support. Since mvebu-mbus is not a platform_driver, the syscore_ops mechanism is used to get ->suspend() and ->resume() hooks called into the driver. In those hooks, we save and restore the MBus windows state, to make sure after resume all Mbus windows are properly restored. Note that while the state of some windows could be gathered by looking again at the Device Tree (for statically described windows), it is not the case of dynamically described windows such as the PCIe memory and I/O windows. Therefore, we take the simple approach of saving and restoring the registers for all MBus windows. In addition, the commit extends the Device Tree binding of the MBus controller, to control the MBus bridge registers (which define which parts of the physical address space is routed to MBus windows vs. normal RAM memory). Those registers must be saved and restored during suspend/resume. The Device Tree binding extension is made is a backward compatible fashion, but of course, suspend/resume will not work without the Device Tree update.

2014-11-27libsas: remove task_collector modeChristoph Hellwig
The task_collector mode (or "latency_injector", (C) Dan Willians) is an optional I/O path in libsas that queues up scsi commands instead of directly sending it to the hardware. It generall increases latencies to in the optiomal case slightly reduce mmio traffic to the hardware. Only the obsolete aic94xx driver and the mvsas driver allowed to use it without recompiling the kernel, and most drivers didn't support it at all. Remove the giant blob of code to allow better optimizations for scsi-mq in the future.

2014-11-26regulator: Document binding for initial and suspend modesJavier Martinez Canillas
Some regulators can run on different operating modes (opmodes). This allows systems to choose the most efficient opmode for each regulator. This patch builds on top of (291d761 regulator: Document binding for regulator suspend state for PM state) adding a regulator-initial-mode DT property to configure at startup the operating mode for regulators that support changing its mode during normal operation and a property regulator-mode to be used in the regulator-state-[mem/disk] nodes for regulators that supports changing its operating mode when the system enters in a suspend state. The set of possible modes that a regulator can operate depends on the hardware capabilities so a list of generic operating modes can't be provided. Instead, each hardware binding should define the list of valid operating modes for the regulators found on that device.
