Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd: "This round is dominated by NXP's i.MX clk drivers. We gained support for two or three i.MX SoCs in here and that mostly means a lot of driver code and data. Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk drivers added in here, and then we get to the long tail of driver updates and non-critical fixes all around, including code for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal. Apart from the usual driver updates we have an update to make registering OF based clk providers a little simpler when they're devices created as a child of a device backed by a node in DT. Drivers don't have to jump through hoops to unregister the provider upon driver removal anymore because the API does the right thing and uses the parent device DT node. Summary: Core: - Make devm_of_clk_add_hw_provider() use parent dt node if necessary - Various SPDX taggings - Mark clk_ops const when possible New Drivers: - NXP i.MX7ULP SoC clock support - NXP i.MX8QXP SoC clock support - NXP i.MX8MQ SoC clock support - NXP QorIQ T1023 SoC support - Qualcomm SDM845 audio subsystem clks - Qualcomm SDM845 GPU clck controllers - Qualcomm QCS404 RPM clk support - Mediatek MT7629 SoC clk controllers - Allwinner F1c100s SoC clocks - Allwinner H6 display engine clocks - Amlogic GX video clocks - Support for Amlogic meson8b CPU frequency scaling - Amlogic Meson8b CPU post-divider clocks Updates: - Proper suspend/resume on VersaClock5 - Shrink code some with DEFINE_SHOW_ATTRIBUTE() - Register fixes for Rockchip rk3188 and rk3328 - One new critical clock for Rockchip rk3188 and a fixed clock id (double used number) - New clock id for Rockchip rk3328 - Amlogic Meson8/Meson8b video clock support - Amlogic got a clk-input helper and used it for the axg-audio clock driver - Sigma Delta modulation for the Allwinner A33 audio clocks - Support for CPEX (timer) clocks on various Renesas R-Car Gen3 and RZ/G2 SoCs - Support for SDHI HS400 clocks on early revisions of Renesas R-Car H3 and M3-W - Support for SDHI and USB clocks on Renesas RZ/A2 - Support for RPC (SPI Multi I/O Bus Controller) clocks on Renesas R-Car V3M - Qualcomm MSM8998 GCC driver improvements (resets, drop unused clks, etc)" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (172 commits) clk: imx: imx7ulp: add arm hsrun mode clocks support dt-bindings: clock: imx7ulp: add HSRUN mode related clocks clk: Use of_node_name_eq for node name comparisons clk: vc5: Add suspend/resume support clk: qcom: Drop unused 8998 clock clk: qcom: Leave mmss noc on for 8998 clk: tegra: Return the exact clock rate from clk_round_rate clk: tegra30: Use Tegra CPU powergate helper function soc/tegra: pmc: Drop SMP dependency from CPU APIs clk: tegra: Fix maximum audio sync clock for Tegra124/210 clk: tegra: get rid of duplicate defines clk: imx: add imx8qxp lpcg driver clk: imx: add lpcg clock support clk: imx: add imx8qxp clk driver clk: imx: Make the i.MX8MQ CCM clock driver CLK_IMX8MQ dependant clk: imx: add scu clock common part clk: imx: add configuration option for mmio clks dt-bindings: clock: add imx8qxp lpcg clock binding dt-bindings: clock: imx8qxp: add SCU clock IDs clk: qcom: Add missing msm8998 resets ...

+* Clock bindings for Freescale i.MX7ULP
+
+i.MX7ULP Clock functions are under joint control of the System
+Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
+modules, and Core Mode Controller (CMC)1 blocks
+
+The clocking scheme provides clear separation between M4 domain
+and A7 domain. Except for a few clock sources shared between two
+domains, such as the System Oscillator clock, the Slow IRC (SIRC),
+and and the Fast IRC clock (FIRCLK), clock sources and clock
+management are separated and contained within each domain.
+
+M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
+A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
+
+Note: this binding doc is only for A7 clock domain.
