git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes From Paul Walmsley via Tony Lindgren: Some OMAP hwmod fixes for v3.11-rc. Mostly intended to fix an earlyprintk regression and an AM33xx cpgmac power management regression. Basic build, boot, and PM tests are available here: http://www.pwsan.com/omap/testlogs/hwmod_fixes_a_v3.11-rc/20130730042132/ The tests include temporary fixes for the unrelated 2430SDP and OMAP3 boot regressions, which are not part of this signed tag. * tag 'for-v3.11-rc/omap-fixes-b' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending: ARM: OMAP2+: hwmod: AM335x: fix cpgmac address space ARM: OMAP2+: hwmod: rt address space index for DT ARM: OMAP2+: Sync hwmod state with the pm_runtime and omap_device state ARM: OMAP2+: Avoid idling memory controllers with no drivers ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL Signed-off-by: Olof Johansson <olof@lixom.net>

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes From Tony Lindgren: Fixes for omap5-uevm regulators from Nishanth Menon <nm@ti.com>: Due to wrong older revision of documentation used as reference, we seem to have a bunch of LDOs wrongly configured on OMAP5 uEVM. This series is based power tree on production board 750-2628-XXX platform. Unfortunately, the wrong voltages may be detrimental to OMAP5 as they supply hardware blocks at voltages that are out of specification. There is a chance that without these fixes there can be hardware damage to omap5-uevm boards with the v3.11-rc series. * tag 'omap-for-v3.11/fixes-omap5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: omap5-uevm: update optional/unused regulator configurations ARM: dts: omap5-uevm: fix regulator configurations mandatory for SoC ARM: dts: omap5-uevm: document regulator signals used on the actual board Signed-off-by: Olof Johansson <olof@lixom.net>

git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into fixes From David Brown, fixes for MSM for 3.11: Two small fixes for MSM. The first fixes the a gpio controller register address. I didn't see any acks from the devicetree maintainers, so I've copied them on this pull request. The change itself is minor, and just to the register address. The second change removes the gpiomux V1 code from MSM.

2013-07-30ARM: OMAP2+: hwmod: AM335x: fix cpgmac address spaceAfzal Mohammed
Register target address to be used for cpgmac is the second device address space. By default, hwmod picks first address space (0th index) for register target. With removal of address space from hwmod and using DT instead, cpgmac is getting wrong address space for register target. Fix it by indicating the address space to be used for register target.

2013-07-30ARM: OMAP2+: hwmod: rt address space index for DTAfzal Mohammed
Address space is being removed from hwmod database and DT information in <reg> property is being used. Currently the 0th index of device address space is used to map for register target address. This is not always true, eg. cpgmac has it's sysconfig in second address space. Handle it by specifying index of device address space to be used for register target. As default value of this field would be zero with static initialization, existing behaviour of using first address space for register target while using DT would be kept as such.

2013-07-30ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LLRajendra Nayak
With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+: Fix serial init for device tree based booting" stubbing out omap_serial_early_init() for Device tree based booting, there was a crash observed on AM335x based devices when hwmod does a _setup_reset() early at boot. This was rootcaused to hwmod trying to reset console uart while earlycon was using it. The way to tell hwmod not to do this is to specify the HWMOD_INIT_NO_RESET flag, which were infact set by the omap_serial_early_init() function by parsing the cmdline to identify the console device. Parsing the cmdline to identify the uart used by earlycon itself seems broken as there is nothing preventing earlycon to use a different one. This patch, instead, attempts to populate the requiste flags for hwmod based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need for cmdline parsing in the DT as well as non-DT cases to identify the uart used by earlycon.

2013-07-29ARM: dts: omap5-uevm: update optional/unused regulator configurationsNishanth Menon
commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7 (ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes) introduced regulator entries for OMAP5uEVM. However, The regulator information is based on an older temporary pre-production board variant and does not reflect production board 750-2628-XXX boards. The following optional/unused regulators can be updated: - SMPS9 supplies TWL6040 over VDDA_2v1_AUD. This regulator needs to be enabled only when audio is active. Since it does not come active by default, it does not require "always-on" or "boot-on". - LDO2 and LDO8 do not go to any peripheral or connector on the board. Further, these unused regulators should have been 2.8V for LDO2 and 3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.

2013-07-29ARM: dts: omap5-uevm: fix regulator configurations mandatory for SoCNishanth Menon
commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7 (ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes) introduced regulator entries for OMAP5uEVM. However, The regulator information is based on an older temporary pre-production board variant and does not reflect production board 750-2628-XXX boards. The following fixes are hence mandatory to ensure right voltage is supplied to key OMAP5 SoC voltage rails: - LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This can only be supplied at 1.5V or 1.8V and we currently supply 2.8V. To prevent any potential device damage risk, use the specified 1.5V-1.8V supply. Remove 'always-on' and 'boot-on' settings here as it is a 'on need' supply to SoC IP and is not enabled by PMIC by default at boot. - LDO3 supplies Low Latency Interface(LLI) hardware module which is a special hardware to communicate with Modem. However since uEVM is not setup by default for this communication, this should be disabled by default. Further, vdda_lli is supposed to be 1.5V and not 3V. - LDO4 supplies VDDAPHY_DISP which is vdda_dsiporta/c/vdda_hdmi This can only be supplied at 1.5V or 1.8V and we currently supply 2.2V. To prevent any potential device damage risk, use the specified 1.5V-1.8V supply. Remove 'always-on' and 'boot-on' settings here as it is a 'on need' supply to SoC IP and is not enabled by PMIC by default at boot. - LDO6 supplies the board specified VDDS_1V2_WKUP supply going to ldo_emu_wkup/vdds_hsic. To stay within the SoC specification supply 1.2V instead of 1.5V. - LDO7 supplies VDD_VPP which is vpp1. This is currently configured for 1.5V which as per data manual "A pulse width of 1000 ns and an amplitude of 2V is required to program each eFuse bit. Otherwise, VPP1 must not be supplied". So, fix the voltage to 2V. and disable the supply since we have no plans of programming efuse bits - it can only be done once - in factory. Further it is not enabled by default by PMIC so, 'boot-on' must be removed, and the 'always-on' needs to be removed to achieve pulsing if efuse needs to be programmed. - LDO9 supplies the board specified vdds_sdcard supply going within SoC specification of 1.8V or 3.0V. Further the supply is controlled by switch enabled by REGEN3. So, introduce REGEN3 and map sdcard slot to be powered by LDO9. Remove 'always-on' allowing the LDO to be disabled on need basis.

With the recent cleanup in Exynos platform code notably commits 17859bec ("ARM: EXYNOS: Do not select legacy Kconfig symbols any more") and b9222210 ("ARM: EXYNOS: Remove mach/gpio.h"), the definition of ARCH_NR_GPIOS got removed.

Enable MMC_UNSAFE_RESUME to accomplish a proper suspend/resume cycle for SD/SDIO/(e)MMC. ARMMMCI host driver supports clock gating through runtime PM, thus MMC_CLKGATE is not needed. Moreover ARMMMCI can do scatter-gather which means we can explicity disable MMC_BLOCK_BOUNCE, since it's default enabled, to skip unnecessary bounce buffer copying.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management and ACPI fixes from Rafael Wysocki: "These are fixes collected over the last week, most importnatly two cpufreq reverts fixing regressions introduced in 3.10, an autoseelp fix preventing systems using it from crashing during shutdown and two ACPI scan fixes related to hotplug. Specifics: - Two cpufreq commits from the 3.10 cycle introduced regressions. The first of them was buggy (it did way much more than it needed to do) and the second one attempted to fix an issue introduced by the first one. Fixes from Srivatsa S Bhat revert both. - If autosleep triggers during system shutdown and the shutdown callbacks of some device drivers have been called already, it may crash the system. Fix from Liu Shuo prevents that from happening by making try_to_suspend() check system_state. - The ACPI memory hotplug driver doesn't clear its driver_data on errors which may cause a NULL poiter dereference to happen later. Fix from Toshi Kani. - The ACPI namespace scanning code should not try to attach scan handlers to device objects that have them already, which may confuse things quite a bit, and it should rescan the whole namespace branch starting at the given node after receiving a bus check notify event even if the device at that particular node has been discovered already. Fixes from Rafael J Wysocki. - New ACPI video blacklist entry for a system whose initial backlight setting from the BIOS doesn't make sense. From Lan Tianyu. - Garbage string output avoindance for ACPI PNP from Liu Shuo. - Two Kconfig fixes for issues introduced recently in the s3c24xx cpufreq driver (when moving the driver to drivers/cpufreq) from Paul Bolle. - Trivial comment fix in pm_wakeup.h from Chanwoo Choi" * tag 'pm+acpi-3.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / video: ignore BIOS initial backlight value for Fujitsu E753 PNP / ACPI: avoid garbage in resource name cpufreq: Revert commit 2f7021a8 to fix CPU hotplug regression cpufreq: s3c24xx: fix "depends on ARM_S3C24XX" in Kconfig cpufreq: s3c24xx: rename CONFIG_CPU_FREQ_S3C24XX_DEBUGFS PM / Sleep: Fix comment typo in pm_wakeup.h PM / Sleep: avoid 'autosleep' in shutdown progress cpufreq: Revert commit a66b2e to fix suspend/resume regression ACPI / memhotplug: Fix a stale pointer in error path ACPI / scan: Always call acpi_bus_scan() for bus check notifications ACPI / scan: Do not try to attach scan handlers to devices having them
