2016-08-15clk: max77686: Combine Maxim max77686 and max77802 driverLaxman Dewangan
The clock IP used on the Maxim PMICs max77686 and max77802 are same. The configuration of clock register is also same except the number of clocks. Part of common code utilisation, there is 3 files for these chips clock driver, one for common and two files for driver registration. Combine both drivers into single file and move common code into same common file reduces the 2 files and make max77686 and max77802 clock driver in single fine. This driver does not depends on the parent driver structure. The regmap handle is acquired through regmap APIs for the register access. This combination of driver helps on adding clock driver for different Maxim PMICs which has similar clock IP like MAX77620 and MAX20024.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "It's the usual big pile of driver updates and additions, but we do have a couple core changes in here as well. Core: - CLK_IS_CRITICAL support has been added. This should allow drivers to properly express that a certain clk should stay on even if their prepare/enable count drops to 0 (and in turn the parents of these clks should stay enabled). - A clk registration API has been added, clk_hw_register(), and an OF clk provider API has been added, of_clk_add_hw_provider(). These APIs have been put in place to further split clk providers from clk consumers, with the goal being to have clk providers never deal with struct clk pointers at all. Conversion of provider drivers is on going. clkdev has also gained support for registering clk_hw pointers directly so we can convert drivers that don't use devicetree. New Drivers: - Marvell ap806 and cp110 system controllers (with clks inside!) - Hisilicon Hi3519 clock and reset controller - Axis ARTPEC-6 clock controllers - Oxford Semiconductor OXNAS clock controllers - AXS10X I2S PLL - Rockchip RK3399 clock and reset controller Updates: - MMC2 and UART2 clks on Samsung Exynos 3250, ACLK on Samsung Exynos 542x SoCs, and some more clk ID exporting for bus frequency scaling - Proper BCM2835 PCM clk support and various other clks - i.MX clk updates for i.MX6SX, i.MX7, and VF610 - Renesas updates for R-Car H3 - Tegra210 got updates for DisplayPort and HDMI 2.0 - Rockchip driver refactorings and fixes due to adding RK3399 support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (139 commits) clk: fix critical clock locking clk: qcom: mmcc-8996: Remove clocks that should be controlled by RPM clk: ingenic: Allow divider value to be divided clk: sunxi: Add display and TCON0 clocks driver clk: rockchip: drop old_rate calculation on pll rate changes clk: rockchip: simplify GRF handling in pll clocks clk: rockchip: lookup General Register Files in rockchip_clk_init clk: rockchip: fix the rk3399 sdmmc sample / drv name clk: mvebu: new driver for Armada CP110 system controller dt-bindings: arm: add DT binding for Marvell CP110 system controller clk: mvebu: new driver for Armada AP806 system controller clk: hisilicon: add CRG driver for hi3519 soc clk: hisilicon: export some hisilicon APIs to modules reset: hisilicon: add reset controller driver for hisilicon SOCs clk: bcm/kona: Do not use sizeof on pointer type clk: qcom: msm8916: Fix crypto clock flags clk: nxp: lpc18xx: Initialize clk_init_data::flags to 0 clk/axs10x: Add I2S PLL clock driver clk: imx7d: fix ahb clock mux 1 clk: fix comment of devm_clk_hw_register() ...

2016-04-20clk: renesas: Provide Kconfig symbols for CPG/MSSR and CPG/MSTP supportGeert Uytterhoeven
Currently the decision whether to build the renesas-cpg-mssr and clk-mstp drivers is handled by Makefile logic. However, the rcar-sysc driver will need to know whether CPG/MSSR and/or CPG/MSTP support are available or not. To avoid having to duplicate this logic, move it to Kconfig. Provide non-visible CLK_RENESAS_CPG_MSSR and CLK_RENESAS_CPG_MSTP Kconfig symbols, which can be used by both Makefiles and C code.

Some board designers, when running out of clock output pads, decide to (mis)use PWM output pads to provide a clock to external components. This driver supports this practice by providing an adapter between the PWM and clock bindings in the device tree. As the PWM bindings specify the period in the device tree, this is a fixed clock.

Additionally the framework core underwent a bit of surgery with two major changes: - The boundary between the clock core and clock providers (e.g clock drivers) is now more well defined with dedicated provider helper functions. struct clk no longer maps 1:1 with the hardware clock but is a true per-user cookie which helps us tracker users of hardware clocks and debug bad behavior. - The addition of rate constraints for clocks. Rate ranges are now supported which are analogous to the voltage ranges in the regulator framework. Unfortunately these changes to the core created some breakeage.

git://git.linaro.org/people/mike.turquette/linux 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 ...
