Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "The large diff this time around is from the addition of a new clk driver for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well. Core: - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops - debugfs ops macroized to shave some lines of boilerplate code - Always calculate the phase instead of caching it in clk_get_phase() - More __must_check on bulk clk APIs New Drivers: - TI's Davinci family of SoCs - Intel's Stratix10 SoC - stm32mp157 SoC - Allwinner H6 CCU - Silicon Labs SI544 clock generator chip - Renesas R-Car M3-N and V3H SoCs - i.MX6SLL SoCs Removed Drivers: - ST-Ericsson AB8540/9540 Updates: - Mediatek MT2701 and MT7622 audsys support and MT2712 updates - STM32F469 DSI and STM32F769 sdmmc2 support - GPIO clks can sleep now - Spreadtrum SC9860 RTC clks - Nvidia Tegra MBIST workarounds and various minor fixes - Rockchip phase handling fixes and a memory leak plugged - Renesas drivers switch to readl/writel from clk_readl/clk_writel - Renesas gained CPU (Z/Z2) and watchdog support - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support - Qualcomm PM8921 PMIC XO buffers - Amlogic migrates to regmap APIs - TI Keystone clk latching support - Allwinner H3 and H5 video clk fixes - Broadcom BCM2835 PLLs needed another bit to enable - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix - i.MX6UL/ULL epdc_podf support - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (233 commits) clk: davinci: add a reset lookup table for psc0 clk: imx: add clock driver for imx6sll dt-bindings: imx: update clock doc for imx6sll clk: imx: add new gate/gate2 wrapper funtion clk: imx: Add CLK_IS_CRITICAL flag for busy divider and busy mux clk: cs2000: set pm_ops in hibernate-compatible way clk: bcm2835: De-assert/assert PLL reset signal when appropriate clk: imx7d: Move clks_init_on before any clock operations clk: imx7d: Correct ahb clk parent select clk: imx7d: Correct dram pll type clk: imx7d: Add USB clock information clk: socfpga: stratix10: add clock driver for Stratix10 platform dt-bindings: documentation: add clock bindings information for Stratix10 clk: ti: fix flag space conflict with clkctrl clocks clk: uniphier: add additional ethernet clock lines for Pro4 clk: uniphier: add SATA clock control support clk: uniphier: add PCIe clock control support clk: Add driver for the si544 clock generator chip clk: davinci: Remove redundant dev_err calls clk: uniphier: add ethernet clock control support for PXs3 ...
