2013-05-29clk: samsung: Add CLK_IGNORE_UNUSED flag for the sysreg clocksSylwester Nawrocki
Currently no driver *) handles the sysreg clock, with an assumption that this clock is always left in its default state (enabled). Before commit 6e6aac7590f902d14d90bace3fd499 ARM: EXYNOS: Migrate clock support to common clock framework the sysreg clock was not even defined and hence wasn't handled explicitly in the kernel. To restore the previous behaviour disable masking the sysreg clock off in the clock core by default. *) Except the Exynos4x12 FIMC-IS driver, which will be modified to not touch the sysreg clock.

2013-05-28clk: wm831x: Fix wm831x_clkout_get_parentAxel Lin
Current code looks strange because calling wm831x_clkout_set_parent() with 0 as parent parameter, wm831x_clkout_get_parent() will return 1. According to the datasheet: R16528 (4090h) Clock Control1 BIT 0: CLKOUT output source select 0 = FLL output 1 = 32.768kHz oscillator Thus fix the entry order in wm831x_clkout_parents[] to make it has the same meaning as the datasheet and make the return value of wm831x_clkout_get_parent() consistent with the parent pass to wm831x_clkout_set_parent().

2013-05-28clk: Fix race condition between clk_set_parent and clk_enable()Saravana Kannan
Without this patch, the following race condition is possible. * clk-A has two parents - clk-X and clk-Y. * All three are disabled and clk-X is current parent. * Thread A: clk_set_parent(clk-A, clk-Y). * Thread A: <snip execution flow> * Thread A: Grabs enable lock. * Thread A: Sees enable count of clk-A is 0, so doesn't enable clk-Y. * Thread A: Updates clk-A SW parent to clk-Y * Thread A: Releases enable lock. * Thread B: clk_enable(clk-A). * Thread B: clk_enable() enables clk-Y, then enabled clk-A and returns. clk-A is now enabled in software, but not clocking in hardware since the hardware parent is still clk-X. The only way to avoid race conditions between clk_set_parent() and clk_enable/disable() is to ensure that clk_enable/disable() calls don't require changes to hardware enable state between changes to software clock topology and hardware clock topology. The options to achieve the above are: 1. Grab the enable lock before changing software/hardware topology and release it afterwards. 2. Keep the clock enabled for the duration of software/hardware topology change so that any additional enable/disable calls don't try to change the hardware state. Once the topology change is complete, the clock can be put back in its original enable state. Option (1) is not an acceptable solution since the set_parent() ops might need to sleep. Therefore, this patch implements option (2). This patch doesn't violate any API semantics. clk_disable() doesn't guarantee that the clock is actually disabled. So, no clients of a clock can assume that a clock is disabled after their last call to clk_disable(). So, enabling the clock during a parent change is not a violation of any API semantics. This also has the nice side effect of simplifying the error handling code.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver changes from Olof Johansson: "This is a rather large set of patches for device drivers that for one reason or another the subsystem maintainer preferred to get merged through the arm-soc tree. There are both new drivers as well as existing drivers that are getting converted from platform-specific code into standalone drivers using the appropriate subsystem specific interfaces. In particular, we can now have pinctrl, clk, clksource and irqchip drivers in one file per driver, without the need to call into platform specific interface, or to get called from platform specific code, as long as all information about the hardware is provided through a device tree. Most of the drivers we touch this time are for clocksource. Since now most of them are part of drivers/clocksource, I expect that we won't have to touch these again from arm-soc and can let the clocksource maintainers take care of these in the future. Another larger part of this series is specific to the exynos platform, which is seeing some significant effort in upstreaming and modernization of its device drivers this time around, which unfortunately is also the cause for the churn and a lot of the merge conflicts. There is one new subsystem that gets merged as part of this series: the reset controller interface, which is a very simple interface for taking devices on the SoC out of reset or back into reset. Patches to use this interface on i.MX follow later in this merge window, and we are going to have other platforms (at least tegra and sirf) get converted in 3.11.

This is primarily useful when there's a driver that doesn't claim clocks properly, but the bootloader leaves them on. It's not expected to be used in normal cases, but for bringup and debug it's very useful to have the option to not gate unclaimed clocks that are still on.

2013-04-23clk: exynos5250: Fix parent clock for sclk_mmc{0,1,2,3}Tushar Behera
commit 688f7d8c9fef ("clk: exynos5250: Fix divider values for sclk_mmc{0,1,2,3}") incorrectly sets the divider for sclk_mmc{0,1,2,3} to fix the wrong clock value. Though this fixed issue with Arndale, it created regressions for other boards like Snow. On Exynos5250, sclk_mmc<n> is generated like below (as per the clock names in drivers/clk/samsung/clk-exynos5250.c) mout_group1_p ==> mout_mmc<n> ==> div_mmc<n> ==> div_mmc_pre<n> => sclk_mmc<n> Earlier div_mmc<n> was set as the parent for sclk_mmc<n>, hence div_mmc_pre<n> was not getting referred in kernel code and depending on its value set during preboot, sclk_mmc<n> value was different for various boards. Setting the correct clock generation path should fix the issues reported in above referenced commit. The changes committed during the earlier patch has also been reverted here.
