Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "This time we've got one core change to introduce a bulk clk_get API, some new clk drivers and updates for old ones. The diff is pretty spread out across a handful of different SoC clk drivers for Broadcom, TI, Qualcomm, Renesas, Rockchip, Samsung, and Allwinner, mostly due to the introduction of new drivers. Core: - New clk bulk get APIs - Clk divider APIs gained the ability to consider a different parent than the current one New Drivers: - Renesas r8a779{0,1,2,4} CPG/MSSR - TI Keystone SCI firmware controlled clks and OMAP4 clkctrl - Qualcomm IPQ8074 SoCs - Cortina Systems Gemini (SL3516/CS3516) - Rockchip rk3128 SoCs - Allwinner A83T clk control units - Broadcom Stingray SoCs - CPU clks for Mediatek MT8173/MT2701/MT7623 SoCs Removed Drivers: - Old non-DT version of the Realview clk driver Updates: - Renesas Kconfig/Makefile cleanups - Amlogic CEC EE clk support - Improved Armada 7K/8K cp110 clk support - Rockchip clk id exposing, critical clk markings - Samsung converted to clk_hw registration APIs - Fixes for Samsung exynos5420 audio clks - USB2 clks for Hisilicon hi3798cv200 SoC and video/camera clks for hi3660" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (147 commits) clk: gemini: Read status before using the value clk: scpi: error when clock fails to register clk: at91: Add sama5d2 suspend/resume gpio: dt-bindings: Add documentation for gpio controllers on Armada 7K/8K clk: keystone: TI_SCI_PROTOCOL is needed for clk driver clk: samsung: audss: Fix silent hang on Exynos4412 due to disabled EPLL clk: uniphier: provide NAND controller clock rate clk: hisilicon: add usb2 clocks for hi3798cv200 SoC clk: Add Gemini SoC clock controller clk: iproc: Remove __init marking on iproc_pll_clk_setup() clk: bcm: Add clocks for Stingray SOC dt-bindings: clk: Extend binding doc for Stingray SOC clk: mediatek: export cpu multiplexer clock for MT8173 SoCs clk: mediatek: export cpu multiplexer clock for MT2701/MT7623 SoCs clk: mediatek: add missing cpu mux causing Mediatek cpufreq can't work clk: renesas: cpg-mssr: Use of_device_get_match_data() helper clk: hi6220: add acpu clock clk: zx296718: export I2S mux clocks clk: imx7d: create clocks behind rawnand clock gate clk: hi3660: Set PPLL2 to 2880M ...
