Add support for spread spectrum clock generation for the audio, video, and DRAM PLLs. Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com> --- Changes in v9: - Add 'Reviewed-by' tag of Peng Fan for imx8mn platform patches - Fix building warning raised by the kernel test robot for patch v8, 11/18 clk: imx: add support for i.MX8MN anatop clock driver - Add patches for imx8m{m,p} platforms: - 23/23 clk: imx8mm: support spread spectrum clock generation - 22/23 clk: imx: add support for i.MX8MM anatop clock driver - 21/23 clk: imx8mp: support spread spectrum clock generation - 20/23 clk: imx8mp: rename ccm_base to base - 19/23 clk: imx: add support for i.MX8MP anatop clock driver Changes in v8: - Drop the patches added in version 7: - 10/23 dt-bindings: clock: imx8m-clock: add phandle to the anatop - 11/23 arm64: dts: imx8mm: add phandle to anatop within CCM - 12/23 arm64: dts: imx8mn: add phandle to anatop within CCM - 13/23 arm64: dts: imx8mp: add phandle to anatop within CCM - 14/23 arm64: dts: imx8mq: add phandle to anatop within CCM Changes in v7: - Add and manage fsl,anatop property as phandle to the anatop node with the new patches: - 10/23 dt-bindings: clock: imx8m-clock: add phandle to the anatop - 11/23 arm64: dts: imx8mm: add phandle to anatop within CCM - 12/23 arm64: dts: imx8mn: add phandle to anatop within CCM - 13/23 arm64: dts: imx8mp: add phandle to anatop within CCM - 14/23 arm64: dts: imx8mq: add phandle to anatop within CCM Changes in v6: - Merge patches: 10/20 dt-bindings: clock: imx8mm: add binding definitions for anatop 11/20 dt-bindings: clock: imx8mn: add binding definitions for anatop 12/20 dt-bindings: clock: imx8mp: add binding definitions for anatop to 05/20 dt-bindings: clock: imx8m-anatop: define clocks/clock-names now renamed 05/18 dt-bindings: clock: imx8m-anatop: add oscillators and PLLs - Split the patch 15/20 dt-bindings-clock-imx8m-clock-support-spread-spectru.patch into 12/18 dt-bindings: clock: imx8m-clock: add PLLs 16/18 dt-bindings: clock: imx8m-clock: support spread spectrum clocking Changes in v5: - Fix compilation errors. - Separate driver code from dt-bindings Changes in v4: - Add dt-bindings for anatop - Add anatop driver - Drop fsl,ssc-clocks from spread spectrum dt-bindings Changes in v3: - Patches 1/8 has been added in version 3. The dt-bindings have been moved from fsl,imx8m-anatop.yaml to imx8m-clock.yaml. The anatop device (fsl,imx8m-anatop.yaml) is indeed more or less a syscon, so it represents a memory area accessible by ccm (imx8m-clock.yaml) to setup the PLLs. - Patches {3,5}/8 have been added in version 3. - Patches {4,6,8}/8 use ccm device node instead of the anatop one. Changes in v2: - Add "allOf:" and place it after "required:" block, like in the example schema. - Move the properties definition to the top-level. - Drop unit types as requested by the "make dt_binding_check" command. drivers/clk/imx/clk-imx8mm.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
