Pull ARM updates from Russell King: "This contains the usual updates from other people (listed below) and the usual random muddle of miscellaneous ARM updates which cover some low priority bug fixes and performance improvements. I've started to put the pull request wording into the merge commits, which are: - NoMMU stuff: This includes the following series sent earlier to the list: - nommu-fixes - R7 Support - MPU support I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I were discussing today until we've reached a conclusion/that's had some more review. This is rebased (and re-tested) on your devel-stable branch because otherwise there were going to be conflicts with Uwe's V7M work now that you've merged that. I've included the fix for limiting MPU to CPU_V7. - Huge page support These changes bring both HugeTLB support and Transparent HugePage (THP) support to ARM. Only long descriptors (LPAE) are supported in this series. The code has been tested on an Arndale board (Exynos 5250). - LPAE updates Please pull these miscellaneous LPAE fixes I've been collecting for a while now for 3.11. They've been tested and reviewed by quite a few people, and most of the patches are pretty trivial. -- Will Deacon. - arch_timer cleanups Please pull these arch_timer cleanups I've been holding onto for a while. They're the same as my last posting, but have been rebased to v3.10-rc3. - mpidr linearisation (multiprocessor id register - identifies which CPU number we are in the system) This patch series that implements MPIDR linearization through a simple hashing algorithm and updates current cpu_{suspend}/{resume} code to use the newly created hash structures to retrieve context pointers. It represents a stepping stone for the implementation of power management code on forthcoming multi-cluster ARM systems. It has been tested on TC2 (dual cluster A15xA7 system), iMX6q, OMAP4 and Tegra, with processors hitting low-power states requiring warm-boot resume through the cpu_resume code path" * 'for-linus' of git://git.linaro.org/people/rmk/linux-arm: (77 commits) ARM: 7775/1: mm: Remove do_sect_fault from LPAE code ARM: 7777/1: Avoid extra calls to the C compiler ARM: 7774/1: Fix dtb dependency to use order-only prerequisites ARM: 7770/1: remove residual ARMv2 support from decompressor ARM: 7769/1: Cortex-A15: fix erratum 798181 implementation ARM: 7768/1: prevent risks of out-of-bound access in ASID allocator ARM: 7767/1: let the ASID allocator handle suspended animation ARM: 7766/1: versatile: don't mark pen as __INIT ARM: 7765/1: perf: Record the user-mode PC in the call chain.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-06-17ARM: imx: create mxc_arch_reset_init_dt() for DT bootShawn Guo
The mxc_arch_reset_init() uses static mapping and calls clk_get_sys() to get clock. It's suitable for non-DT boot but not for DT boot where dynamic mapping and of_clk_get() should be used instead.

2013-06-17ARM: imx: move clk_prepare() out from mxc_restart()Shawn Guo

Move clk_get() and clk_prepare() into mxc_arch_reset_init() and only have the atomic part clk_enable() be called in mxc_restart(). As a result, mxc_arch_reset_init() needs to be called after clk gets initialized. While there, it also changes printk(KERN_ERR ...) to pr_err() and adds __init annotation for mxc_arch_reset_init().

This configuration is taken from Freescale's kernel patch "ENGR00153601 [MX6]Adjust L2 cache parameter" [1] with two additional improvements: a) The L2X0_POWER_CTRL has only the two bits we set. So no need to read the register before.

2013-06-17ARM: i.MX5: Allow DT clock providersMartin Fuzzey
Currently clock providers defined in the DT are not registered on i.MX5 platforms since of_clk_init() is not called. This is not a problem for the SOC's own clocks, which are registered in code, but prevents the DT being used to define clocks for external hardware. Fix this by calling of_clk_init() and actually using the DT to obtain the 4 SOC fixed clocks. These are already defined in the DT but were previously just used to manually obtain the rate. Fall back to the old scheme for non DT platforms. Since the same method may be useful for other i.MX platforms implement the imx_obtain_fixed_clock() function in common code. Actually changing other i.MX platforms to use this should be done later by someone with access to the appropriate hardware.

2013-05-12ARM i.MX6: correct MLB clock configurationDirk Behme
According to the i.MX6 Dual/Quad technical reference manual (Figure 18-2. Clock Tree - Part 1) the MLB clock is directly feed by the AXI_CLK_ROOT. This is called 'axi' in our code. Note that the clock of the MLB IP block on the i.MX6 is completely independent of the PLL8 (MLB PLL). The MLB PLL isn't responsible for feeding the MLB IP block with a clock. Instead, it's used internally by the MLB module to sync the bus clock in case the MLB 6-pin interface is enabled: MediaLB Control 0 Register, MLB150_MLBC0[5], MLBPEN: 1 MediaLB 6-pin interface enabled. MLB PLL and MLB PHY is enabled in this case. I.e. the PLL8 MLB PLL has to be handled by the MLB driver and isn't needed for clocking the MLB module itself.

Commit bca7a5a (ARM: cpu hotplug: remove majority of cache flushing from platforms) removes include of <asm/cacheflush.h> and hence discovers a few indirect inclusion and declaration problems as below.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates (part 3) from Arnd Bergmann: "This is the third and smallest of the SoC specific updates. Changes include: - SMP support for the Xilinx zynq platform - Smaller imx changes - LPAE support for mvebu - Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/. We expect other similar drivers to get moved to the same place in order to avoid creating more top-level directories under drivers/ or cluttering up the messy drivers/misc/ even more." * tag 'soc-for-linus-3' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (50 commits) ARM: imx: reset_controller may be disabled ARM: mvebu: Align the internal registers virtual base to support LPAE ARM: mvebu: Limit the DMA zone when LPAE is selected arm: plat-orion: remove addr-map code arm: mach-mv78xx0: convert to use the mvebu-mbus driver arm: mach-orion5x: convert to use mvebu-mbus driver arm: mach-dove: convert to use mvebu-mbus driver arm: mach-kirkwood: convert to use mvebu-mbus driver arm: mach-mvebu: convert to use mvebu-mbus driver ARM i.MX53: set CLK_SET_RATE_PARENT flag on the tve_ext_sel clock ARM i.MX53: tve_di clock is not part of the CCM, but of TVE ARM i.MX53: make tve_ext_sel propagate rate change to PLL ARM i.MX53: Remove unused tve_gate clkdev entry ARM i.MX5: Remove tve_sel clock from i.MX53 clock tree ARM: i.MX5: Add PATA and SRTC clocks ARM: imx: do not bring up unavailable cores ARM: imx: add initial imx6dl support ARM: imx1: mm: add call to mxc_device_init ARM: imx_v4_v5_defconfig: Add CONFIG_GPIO_SYSFS ARM: imx_v6_v7_defconfig: Select CONFIG_PERF_EVENTS ...

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next Pull MFD update from Samuel Ortiz: "For 3.10 we have a few new MFD drivers for: - The ChromeOS embedded controller which provides keyboard, battery and power management services. This controller is accessible through i2c or SPI. - Silicon Laboratories 476x controller, providing access to their FM chipset and their audio codec. - Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based reader. - Nokia's Tahvo power button and watchdog device. This device is very similar to Retu and is thus supported by the same code base. - STMicroelectronics STMPE1801, a keyboard and GPIO controller supported by the stmpe driver. - ST-Ericsson AB8540 and AB8505 power management and voltage converter controllers through the existing ab8500 code. Some other drivers got cleaned up or improved. In particular: - The Linaro/STE guys got the ab8500 driver in sync with their internal code through a series of optimizations, fixes and improvements. - The AS3711 and OMAP USB drivers now have DT support. - The arizona clock and interrupt handling code got improved. - The wm5102 register patch and boot mechanism also got improved." * tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next: (104 commits) mfd: si476x: Don't use 0bNNN mfd: vexpress: Handle pending config transactions mfd: ab8500: Export ab8500_gpadc_sw_hw_convert properly mfd: si476x: Fix i2c warning mfd: si476x: Add header files and Kbuild plumbing mfd: si476x: Add chip properties handling code mfd: si476x: Add the bulk of the core driver mfd: si476x: Add commands abstraction layer mfd: rtsx: Support RTS5249 mfd: retu: Add Tahvo support mfd: ucb1400: Pass ucb1400-gpio data through ac97 bus mfd: wm8994: Add some OF properties mfd: wm8994: Add device ID data to WM8994 OF device IDs input: Export matrix_keypad_parse_of_params() mfd: tps65090: Add compatible string for charger subnode mfd: db8500-prcmu: Support platform dependant device selection mfd: syscon: Fix warnings when printing resource_size_t of: Add stub of_get_parent for non-OF builds mfd: omap-usb-tll: Convert to devm_ioremap_resource() mfd: omap-usb-host: Convert to devm_ioremap_resource() ...
