It is a collection of various clk driver updates. The biggest driver updates in terms of lines of code is the Allwinner driver, closely followed by the Qualcomm and Mediatek drivers. All of those hit high because we add so many lines of clk data. Coming in fourth place is i.MX which also adds a bunch of clk data. This accounts for the new driver additions this time around. Otherwise the patches are lots of little cleanups and fixes for various clk drivers that have baked in linux-next for a while. I suppose one highlight or theme is that more clk drivers are being updated to work as modules, which is interesting to see such critical SoC infrastructure work as a loadable module. New Drivers: - Support qcom SM8150/SM8250 video and display clks - Support Mediatek MT8167 clks - Add clock for CRC block found on vf610 SoCs - Add support for the Renesas R-Car V3U (R8A779A0) SoC - Add support for the VSP for Resizing clock on Renesas RZ/G1H - Support Allwinner A100 SoC clks Removed Drivers: - Remove i.MX21 clock driver, as i.MX21 platform support is being dropped Updates: - Change how qcom's display port clks work - Small non-critical fixes for TI clk driver - Remove various unused variables in clk drivers - Allow Rockchip clk driver to be a module - Remove most __clk_lookup() calls in Samsung drivers (yay!) - Support building i.MX ARMv8 platforms clock driver as module - Some kerneldoc fixes here and there - A couple of minor i.MX clk data corrections - Update audio clock inverter and fdiv2 flag on Amlogic g12 - Make amlogic clk drivers configurable in Kconfig - Fix Renesas VSP clock names to match corrected hardware documentation - Sigma-delta modulation on Allwinner R40 - Various fixes for at91 clk driver - Use semicolons instead of commas in some places - Mark some variables const so they can move to RO memory" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (102 commits) clk: imx8mq: Fix usdhc parents order clk: qcom: gdsc: Keep RETAIN_FF bit set if gdsc is already on clk: Restrict CLK_HSDK to ARC_SOC_HSDK clk: at91: sam9x60: support only two programmable clocks clk: ingenic: Respect CLK_SET_RATE_PARENT in .round_rate clk: ingenic: Don't tag custom clocks with CLK_SET_RATE_PARENT clk: ingenic: Don't use CLK_SET_RATE_GATE for PLL clk: ingenic: Use readl_poll_timeout instead of custom loop clk: ingenic: Use to_clk_info() macro for all clocks clk: bcm2835: add missing release if devm_clk_hw_register fails clk: at91: clk-sam9x60-pll: remove unused variable clk: at91: clk-main: update key before writing AT91_CKGR_MOR clk: at91: remove the checking of parent_name clk: clk-prima2: fix return value check in prima2_clk_init() clk: mmp2: Fix the display clock divider base clk: pxa: Constify static struct clk_ops clk: baikal-t1: Mark Ethernet PLL as critical clk: qoriq: modify MAX_PLL_DIV to 32 clk: axi-clkgen: Set power bits for fractional mode clk: axi-clkgen: Add support for fractional dividers ...
