2014-04-01drivers: reset: stih416: add softreset controllerSrinivas Kandagatla
This patch adds softreset controller for STiH416 SOC, soft reset controller is based on system configuration registers which are mapped via regmap. This reset controller does not have any feedback or acknowledgement. With this patch a new device "st,stih416-softreset" is registered with system configuration registers based reset controller that controls the softreset state of the hardware such as Ethernet, IRB.

On the newly introduced sama5d36, Gigabit and 10/100 Ethernet network interfaces are probed in a different order than for the sama5d35. Moreover, users are accustomed to this order in bootloaders and backports for older kernel revisions. So this patch switches DT node order as it is done for the other dual-Ethernet sama5d3 SoC. Better interface numbering which does not depend on DT node order is being developed for stronger interface identification.

2014-03-07ARM: 7991/1: sa1100: fix compile problem on CollieLinus Walleij
Due to a problem in the MFD Kconfig it was not possible to compile the UCB battery driver for the Collie SA1100 system, in turn making it impossible to compile in the battery driver. (See patch "mfd: include all drivers in subsystem menu".) After fixing the MFD Kconfig (separate patch) a compile error appears in the Collie battery driver due to the <mach/collie.h> implicitly requiring <mach/hardware.h> through <linux/gpio.h> via <mach/gpio.h> prior to commit 40ca061b "ARM: 7841/1: sa1100: remove complex GPIO interface".

2014-03-07ARM: fix noMMU kallsyms symbol filteringRussell King
With noMMU, CONFIG_PAGE_OFFSET was not being set correctly. As there's no MMU, PAGE_OFFSET should be equal to PHYS_OFFSET in all cases. This commit makes that explicit. Since we do this, we don't need to mess around in asm/memory.h with ifdefs to sort this out, so let's get rid of that, and there's no point offering the "Memory split" option for noMMU as that's meaningless there.

2014-02-27arm/arm64: KVM: detect CPU reset on CPU_PM_EXITMarc Zyngier
Commit 1fcf7ce0c602 (arm: kvm: implement CPU PM notifier) added support for CPU power-management, using a cpu_notifier to re-init KVM on a CPU that entered CPU idle. The code assumed that a CPU entering idle would actually be powered off, loosing its state entierely, and would then need to be reinitialized. It turns out that this is not always the case, and some HW performs CPU PM without actually killing the core. In this case, we try to reinitialize KVM while it is still live. It ends up badly, as reported by Andre Przywara (using a Calxeda Midway): [ 3.663897] Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x685760 [ 3.663897] unexpected data abort in Hyp mode at: 0xc067d150 [ 3.663897] unexpected HVC/SVC trap in Hyp mode at: 0xc0901dd0 The trick here is to detect if we've been through a full re-init or not by looking at HVBAR (VBAR_EL2 on arm64). This involves implementing the backend for __hyp_get_vectors in the main KVM HYP code (rather small), and checking the return value against the default one when the CPU notifier is called on CPU_PM_EXIT.

Merely reverting the fix and waiting until v3.15 isn't a good option because there is code in v3.14 that depends on the revised behaviour to boot.

2014-02-21ARM: 7980/1: kernel: improve error message when LPAE config doesn't match CPUThomas Petazzoni
Currently, when the kernel is configured with LPAE support, but the CPU doesn't support it, the error message is fairly cryptic: Error: unrecognized/unsupported processor variant (0x561f5811). This messages is normally shown when there is an issue when comparing the processor ID (CP15 0, c0, c0) with the values/masks described in proc-v7.S. However, the same message is displayed when LPAE support is enabled in the kernel configuration, but not available in the CPU, after looking at ID_MMFR0 (CP15 0, c0, c1, 4). Having the same error message is highly misleading. This commit improves this by showing a different error message when this situation occurs: Error: Kernel with LPAE support, but CPU does not support LPAE.

2014-02-20of: Move testcase FDT data into drivers/ofGrant Likely
The testcase data is usable by any platform. This patch moves it into the drivers/of directory so it can be included by any architecture. Using the test cases requires manually adding #include <testcases.dtsi> to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not pretty though. A useful project would be to make the testcase code easier to execute. Signed-off-by: Grant Likely <grant.likely@linaro.org>
2014-02-19ARM: OMAP2+: clock: fix clkoutx2 with CLK_SET_RATE_PARENTTomi Valkeinen
If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling clk_set_rate() on the clock "skips" the x2 multiplier as there are no set_rate and round_rate functions defined for the clkoutx2. This results in getting double the requested clock rates, breaking the display on omap3430 based devices. This got broken when d0f58bd3bba3877fb1af4664c4e33273d36f00e4 and related patches were merged for v3.14, as omapdss driver now relies more on the clk-framework and CLK_SET_RATE_PARENT. This patch implements set_rate and round_rate for clkoutx2. Tested on OMAP3430, OMAP3630, OMAP4460.
