Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk framework updates from Stephen Boyd: "The core clk framework changes are small again. They're mostly minor fixes that weren't causing enough problems (or any problems when we're just clarifying things) to warrant sending outside the merge window. The majority of changes are in drivers for various SoCs. Full details are in the logs, but here's the summary. Core: - Better support for DeviceTree overlays with the addition of the CLK_OF_DECLARE_DRIVER macro. Now we won't probe a clk driver for a device node that matched during of_clk_init(), unless the driver uses CLK_OF_DECLARE_DRIVER instead of CLK_OF_DECLARE. This allows overlays to work cleanly for drivers that must probe before the device model is ready, and also after it's ready when an overlay is loaded. - Clarification in the code around how clk_hw pointers are returned from of clk providers - Proper migration of prepare/enable counts to parents when the clk tree is constructed New Drivers: - Socionext's UniPhier SoCs - Loongson1C - ZTE ZX296718 - Qualcomm MDM9615 - Amlogic GXBB AO clocks and resets - Broadcom BCM53573 ILP - Maxim MAX77620 Updates: - Four Allwinner SoCs are migrated to the new style clk driver (A31, A31s, A23 and A33) - Exynos 5xxx audio and DRAM clks - Loongson1B AC97, DMA and NAND clks - Rockchip DDR clks and rk3399 driver tweaks - Renesas R-Car M3-W (r8a7796) SoC SDHI interface and Watchdog timer clks - Renasas R-Car H3 and M3-W CMT clks and RAVB+Thermal clks for M3-W - Amlogic GXBB MMC gate clks - at91 sama5d4 sckc - Removal of STiH415 and STiH416 clk support as the SoC is being removed - Rework of STiH4xx clk support for new style bindings - Continuation of driver migration to clk_hw based registration APIs - xgene PMD support - bcm2835 critical clk markings - ARM versatile ICST" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (199 commits) CLK: Add Loongson1C clock support clk: Loongson1: Make use of GENMASK clk: Loongson1: Update clocks of Loongson1B clk: Loongson1: Refactor Loongson1 clock clk: change the type of clk_hw_onecell_data.num to unsigned int clk: zx296718: register driver earlier with core_initcall clk: mvebu: dynamically allocate resources in Armada CP110 system controller clk: mvebu: fix setting unwanted flags in CP110 gate clock clk: nxp: clk-lpc32xx: Unmap region obtained by of_iomap clk: mediatek: clk-mt8173: Unmap region obtained by of_iomap clk: sunxi-ng: Fix reset offset for the A23 and A33 clk: at91: sckc: optimize boot time clk: at91: Add sama5d4 sckc support clk: at91: move slow clock controller clocks to sckc.c clk: imx6: initialize GPU clocks clk: imx6: fix i.MX6DL clock tree to reflect reality clk: imx53: Add clocks configuration clk: uniphier: add clock data for UniPhier SoCs clk: uniphier: add core support code for UniPhier clock driver clk: bcm: Add driver for BCM53573 ILP clock ...

-Binding for Maxim MAX77802 32k clock generator block
-
-This is a part of device tree bindings of MAX77802 multi-function device.
-More information can be found in bindings/mfd/max77802.txt file.
-
-The MAX77802 contains two 32.768khz clock outputs that can be controlled
-(gated/ungated) over I2C.
-
-Following properties should be present in main device node of the MFD chip.
-
-Required properties:
-- #clock-cells: From common clock binding; shall be set to 1.
-
-Optional properties:
-- clock-output-names: From common clock binding.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. Following indices are allowed:
- - 0: 32khz_ap clock,
- - 1: 32khz_cp clock.
-
-Clocks are defined as preprocessor macros in dt-bindings/clock/maxim,max77802.h
-header and can be used in device tree sources.
