2014-10-15Merge tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linuxLinus Torvalds8-5/+108
Pull clock tree updates from Mike Turquette: "The clk tree changes for 3.18 are dominated by clock drivers. Mostly fixes and enhancements to existing drivers as well as new drivers. This tag contains a bit more arch code than I usually take due to some OMAP2+ changes. Additionally it contains the restart notifier handlers which are merged as a dependency into several trees. The PXA changes are the only messy part. Due to having a stable tree I had to revert one patch and follow up with one more fix near the tip of this tag. Some dead code is introduced but it will soon become live code after 3.18-rc1 is released as the rest of the PXA family is converted over to the common clock framework. Another trend in this tag is that multiple vendors have started to push the complexity of changing their CPU frequency into the clock driver, whereas this used to be done in CPUfreq drivers. Changes to the clk core include a generic gpio-clock type and a clk_set_phase() function added to the top-level clk.h api. Due to some confusion on the fbdev mailing list the kernel boot parameters documentation was updated to further explain the clk_ignore_unused parameter, which is often required by users of the simplefb driver. Finally some fixes to the locking around the clock debugfs stuff was done to prevent deadlocks when interacting with other subsystems." * tag 'clk-for-linus-3.18' of git://git.linaro.org/people/mike.turquette/linux: (99 commits) clk: pxa clocks build system fix Revert "arm: pxa: Transition pxa27x to clk framework" clk: samsung: register restart handlers for s3c2412 and s3c2443 clk: rockchip: add restart handler clk: rockchip: rk3288: i2s_frac adds flag to set parent's rate doc/kernel-parameters.txt: clarify clk_ignore_unused arm: pxa: Transition pxa27x to clk framework dts: add devicetree bindings for pxa27x clocks clk: add pxa27x clock drivers arm: pxa: add clock pll selection bits clk: dts: document pxa clock binding clk: add pxa clocks infrastructure clk: gpio-gate: Ensure gpiod_ APIs are prototyped clk: ti: dra7-atl-clock: Mark the device as pm_runtime_irq_safe clk: ti: LLVMLinux: Move __init outside of type definition clk: ti: consider the fact that of_clk_get() might return an error clk: ti: dra7-atl-clock: fix a memory leak clk: ti: change clock init to use generic of_clk_init clk: hix5hd2: add I2C clocks clk: hix5hd2: add watchdog0 clocks ...

Allwinner Clocks Additions for 3.18 The most important part of this serie is the addition of the phase API to handle the MMC clocks in the Allwinner SoCs. Apart from that, the A23 gained a new mbus driver, and there's a fix for a incorrect divider table on the APB0 clock.

The MMC clock we thought we had until now are actually not one but three different clocks. The main one is unchanged, and will have three outputs: - The clock fed into the MMC - a sample and output clocks, to deal with when should we output/sample data to/from the MMC bus The phase control we had are actually controlling the two latter clocks, but the main MMC one is unchanged. We can adjust the phase with a 3 bits value, from 0 to 7, 0 meaning a 180 phase shift, and the other values being the number of periods from the MMC parent clock to outphase the clock of.

2014-09-09clk: max77686: Improve Maxim 77686 PMIC clocks bindingJavier Martinez Canillas1-4/+12
Like most clock drivers, the Maxim 77686 PMIC clock binding follows the convention that the "#clock-cells" property is used to specify the number of cells in a clock provider. But the binding document is not clear enough that it shall be set to 1 since the PMIC support multiple clocks outputs. Also, explain that the clocks identifiers are defined in a header file that can be included by Device Tree source with client nodes to avoid using magic numbers. Finally, add "clock-output-names" as an optional property since now is supported by the clock driver.

2014-07-16clk: mvebu: extend clk-cpu for dynamic frequency scalingThomas Petazzoni1-2/+3
This commit extends the existing clk-cpu driver used on Marvell Armada XP platforms to support the dynamic frequency scaling of the CPU clock. Non-dynamic frequency change was already supported (and used before secondary CPUs are started), but the dynamic frequency change requires a completely different procedure. In order to achieve this, the clk_cpu_set_rate() function is reworked to handle two separate cases: - The case where the clock is enabled, which is the new dynamic frequency change code, implemented in clk_cpu_on_set_rate(). This part will be used for cpufreq activities. - The case where the clock is disabled, which is the existing frequency change code, moved in clk_cpu_off_set_rate(). This part is already used to set the clock frequency of the secondary CPUs before starting them. In order to implement the dynamic frequency change function, we need to access the PMU DFS registers, which are outside the currently mapped "Clock Complex" registers, so a new area of registers is now mapped. This affects the Device Tree binding, but we are careful to do it in a backward-compatible way (by allowing the second pair of registers to be non-existent, and in this case, ensuring clk_cpu_on_set_rate() returns an error). Note that technically speaking, the clk_cpu_on_set_rate() does not do the entire procedure needed to change the frequency dynamically, as it involves touching a number of PMSU registers. This is done through a clock notifier registered by the PMSU driver in followup commits.

2014-07-15clk: qcom: Add support for APQ8064 multimedia clocksStephen Boyd1-0/+1
The APQ8064 multimedia clock controller is fairly similar to the 8960 multimedia clock controller, except that gfx2d0/1 has been removed and the gfx3d frequency is slightly faster when using the newly introduced PLL15. We also add vcap clocks and a couple new TV clocks. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2014-07-15clk: qcom: Add support for IPQ8064's global clock controller (GCC)Kumar Gala1-0/+1
Add a driver for the global clock controller found on IPQ8064 based platforms. This should allow most non-multimedia device drivers to probe and control their clocks. This is currently missing clocks for USB HSIC and networking devices.

2014-07-04clk: sunxi: Add A23 clocks supportChen-Yu Tsai1-0/+5
The clock control unit on the A23 is similar to the one found on the A31. The AHB1, APB1, APB2 gates on the A23 are almost identical to the ones on the A31, but some outputs are missing. The main CPU PLL (PLL1) however is like that on older Allwinner SoCs, such as the A10 or A20, but the N factor starts from 1 instead of 0. This patch adds support for PLL1 and all the basic clock muxes and gates.

2014-07-01dt/bindings: Binding documentation for Palmas clk32kg and clk32kgaudio clocksPeter Ujfalusi1-0/+35
Palmas class of devices can provide 32K clock(s) to be used by other devices on the board. Depending on the actual device the provided clocks can be: CLK32K_KG and CLK32K_KGAUDIO or only one: CLK32K_KG (TPS659039 for example) Use separate compatible flags for the two 32K clock. A system which needs or have only one of the 32k clock from Palmas will need to add node(s) for each clock as separate section in the dts file. The two compatible property is: "ti,palmas-clk32kg" for clk32kg clock "ti,palmas-clk32kgaudio" for clk32kgaudio clock Apart from the register control of the clocks - which is done via the clock API there is a posibility to enable the external sleep control. In this way the clock can be enabled/disabled on demand by the user of the clock.
