git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18 commits) and system suspend/hibernation (9 commits). From the new code perspective, the ACPICA update brings ACPI 5.1 to the table, including a new device configuration object called _DSD (Device Specific Data) that will hopefully help us to operate device properties like Device Trees do (at least to some extent) and changes related to supporting ACPI on ARM. Apart from that we have hibernation changes making it use radix trees to store memory bitmaps which should speed up some operations carried out by it quite significantly. We also have some power management changes related to suspend-to-idle (the "freeze" sleep state) support and more preliminary changes needed to support ACPI on ARM (outside of ACPICA). The rest is fixes and cleanups pretty much everywhere. Specifics: - ACPICA update to upstream version 20140724. That includes ACPI 5.1 material (support for the _CCA and _DSD predefined names, changes related to the DMAR and PCCT tables and ARM support among other things) and cleanups related to using ACPICA's header files. A major part of it is related to acpidump and the core code used by that utility. Changes from Bob Moore, David E Box, Lv Zheng, Sascha Wildner, Tomasz Nowicki, Hanjun Guo. - Radix trees for memory bitmaps used by the hibernation core from Joerg Roedel. - Support for waking up the system from suspend-to-idle (also known as the "freeze" sleep state) using ACPI-based PCI wakeup signaling (Rafael J Wysocki). - Fixes for issues related to ACPI button events (Rafael J Wysocki). - New device ID for an ACPI-enumerated device included into the Wildcat Point PCH from Jie Yang. - ACPI video updates related to backlight handling from Hans de Goede and Linus Torvalds. - Preliminary changes needed to support ACPI on ARM from Hanjun Guo and Graeme Gregory. - ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui. - Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros (Rafael J Wysocki). - ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J Wysocki. - Cleanups and improvements related to system suspend from Lan Tianyu, Randy Dunlap and Rafael J Wysocki. - ACPI battery cleanup from Wei Yongjun. - cpufreq core fixes from Viresh Kumar. - Elimination of a deadband effect from the cpufreq ondemand governor and intel_pstate driver cleanups from Stratos Karafotis. - 350MHz CPU support for the powernow-k6 cpufreq driver from Mikulas Patocka. - Fix for the imx6 cpufreq driver from Anson Huang. - cpuidle core and governor cleanups from Daniel Lezcano, Sandeep Tripathy and Mohammad Merajul Islam Molla. - Build fix for the big_little cpuidle driver from Sachin Kamat. - Configuration fix for the Operation Performance Points (OPP) framework from Mark Brown. - APM cleanup from Jean Delvare. - cpupower utility fixes and cleanups from Peter Senna Tschudin, Andrey Utkin, Himangi Saraogi, Rickard Strandqvist, Thomas Renninger" * tag 'pm+acpi-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (118 commits) ACPI / LPSS: add LPSS device for Wildcat Point PCH ACPI / PNP: Replace faulty is_hex_digit() by isxdigit() ACPICA: Update version to 20140724.

Pull ARM updates from Russell King: "Included in this update: - perf updates from Will Deacon: The main changes are callchain stability fixes from Jean Pihet and event mapping and PMU name rework from Mark Rutland The latter is preparatory work for enabling some code re-use with arm64 in the future. - updates for nommu from Uwe Kleine-König: Two different fixes for the same problem making some ARM nommu configurations not boot since 3.6-rc1. The problem is that user_addr_max returned the biggest available RAM address which makes some copy_from_user variants fail to read from XIP memory. - deprecate legacy OMAP DMA API, in preparation for it's removal.

2014-07-18ARM: convert all "mov.* pc, reg" to "bx reg" for ARMv6+Russell King
ARMv6 and greater introduced a new instruction ("bx") which can be used to return from function calls. Recent CPUs perform better when the "bx lr" instruction is used rather than the "mov pc, lr" instruction, and this sequence is strongly recommended to be used by the ARM architecture manual (section A.4.1.1). We provide a new macro "ret" with all its variants for the condition code which will resolve to the appropriate instruction. Rather than doing this piecemeal, and miss some instances, change all the "mov pc" instances to use the new macro, with the exception of the "movs" instruction and the kprobes code. This allows us to detect the "mov pc, lr" case and fix it up - and also gives us the possibility of deploying this for other registers depending on the CPU selection.

2014-07-18ARM: i.MX53: globally disable supervisor protectSteffen Trumtrar
Most peripherals on the i.MX53 have an Off-Platform Peripheral Access Control Register (OPACR) in which the access rights (together with the MPROT registers) can be declared. However, this does not seem to work for example for SSI1+SDMA, because the supervisor bit is not set for the SDMA unit. It does work for SSI2, the QSB for example uses SSI2 for its audio. But SSI2 only works because it does NOT have an OPACR. The right solution would be to fix the access rights for the SDMA, but the unit responsible for this is the Central Security Unit (CSU), which of course is NOT documented. So, until documentation for this is openly available, turn off the supervisor protection because it cripples the hardware.

2014-07-18ARM: i.MX: allow disabling supervisor protect via DTSteffen Trumtrar
The i.MX SoCs allow to setup fine grained access rights to peripherals on the AIPS bus. This is done via the Peripheral Access Register (PAR) in e.g. the i.MX21 or in later SoC versions the Off-Platform Peripheral Access Control Register (OPACR), e.g. i.MX53. Under certain circumstances this leads to problems in which bus masters are not granted their access rights to peripherals. To be able to disable these restrictions on DT platforms, add a helper function that looks for AIPS nodes in the DT and disables them for every compatible node it finds. The compatible has to be declared in the mach-specific entry file, where this helper function should then be called.

imx6q_pm_enter calls imx6sl_set_wait_clk when run on an imx6sl based machine.

2014-07-18ARM: imx5: remove mx51.h and mx53.hShawn Guo
Now all the macros in mx51.h and mx53.h are used nowhere, so remove them. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
2014-07-18ARM: imx5: clean function declarations in mx51.hShawn Guo
The mx51_display_revision() is a dead declaration. Remove it. Also, move mx51_revision() into common.h. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
2014-07-18ARM: imx5: remove file mm-imx5.cShawn Guo
The only code left in mm-imx5.c is to create static mapping. While all IMX platform code are moved to use dynamic mapping, the file can just be removed now. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
2014-07-18ARM: imx5: move init hooks into mach-imx5x.cShawn Guo
These imx5 init_early[late] hooks are called only from mach-imx5x.c. Let's move them into mach-imx5x.c. While at it, replace the static mapping in imx51_ipu_mipi_setup() with dynamic mapping. Also this function and imx_src_init() do not necessarily to be called at .init_early hook, so move them into .init_machine. The mxc_iomux_v3_init() is dropped from imx51_init_early() in the moving, since it's only needed by non-DT boot. Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
