Merge tag 'clk-imx-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux into clk-imx
Pull i.MX clk driver changes from Abel Vesa: - Remove unused helpers from i.MX specific clock header - Rework all clk based helpers to use clk_hw based ones - Rework gate/mux/divider wrappers - Rework imx_clk_hw_composite and imx_clk_hw_pll14xx wrappers - Add i.MX8ULP clock driver and related bindings - Update i.MX pllv4 and composite clocks to support i.MX8ULP - Disable i.MX7ULP composite clock during initialization - Add CLK_SET_RATE_NO_REPARENT flag to the i.MX7ULP composite - Disable the pfd when set pfdv2 clock rate - Add support for i.MX8ULP in pfdv2 - Add the pcc reset controller support on i.MX8ULP - Fix the build break when clk-imx8ulp is built as module - Move csi_sel mux to correct base register in i.MX6UL clock drivr - Fix csi clk gate register in i.MX6UL clock driver - Fix build bug making CLK_IMX8ULP select MXC_CLK * tag 'clk-imx-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/abelvesa/linux: (21 commits) clk: imx: Make CLK_IMX8ULP select MXC_CLK clk: imx: imx6ul: Fix csi clk gate register clk: imx: imx6ul: Move csi_sel mux to correct base register clk: imx: Fix the build break when clk-imx8ulp build as module clk: imx: Add the pcc reset controller support on imx8ulp clk: imx: Add clock driver for imx8ulp clk: imx: Update the pfdv2 for 8ulp specific support clk: imx: disable the pfd when set pfdv2 clock rate clk: imx: Add 'CLK_SET_RATE_NO_REPARENT' for composite-7ulp clk: imx: disable i.mx7ulp composite clock during initialization clk: imx: Update the compsite driver to support imx8ulp clk: imx: Update the pllv4 to support imx8ulp dt-bindings: clock: Add imx8ulp clock support clk: imx: Rework imx_clk_hw_pll14xx wrapper clk: imx: Rework all imx_clk_hw_composite wrappers clk: imx: Rework all clk_hw_register_divider wrappers clk: imx: Rework all clk_hw_register_mux wrappers clk: imx: Rework all clk_hw_register_gate2 wrappers clk: imx: Rework all clk_hw_register_gate wrappers clk: imx: Make mux/mux2 clk based helpers use clk_hw based ones ...
