Hello, This patchset adds common clock driver for Bitmain BM1880 SoC clock controller. The clock controller consists of gate, divider, mux and pll clocks with different compositions. Hence, the driver uses composite clock structure in place where multiple clocking units are combined together. This patchset also removes UART fixed clock and sources clocks from clock controller for Sophon Edge board where the driver has been validated. Thanks, Mani Changes in v2: * Converted the dt binding to YAML * Incorporated review comments from Stephen (majority of change is switching to new way of specifying clk parents) Manivannan Sadhasivam (7): dt-bindings: clock: Add devicetree binding for BM1880 SoC arm64: dts: bitmain: Add clock controller support for BM1880 SoC arm64: dts: bitmain: Source common clock for UART controllers clk: Add common clock driver for BM1880 SoC MAINTAINERS: Add entry for BM1880 SoC clock driver clk: Warn if clk_init_data is not zero initialized clk: Zero init clk_init_data in helpers .../bindings/clock/bitmain,bm1880-clk.yaml | 83 ++ MAINTAINERS | 2 + .../boot/dts/bitmain/bm1880-sophon-edge.dts | 9 - arch/arm64/boot/dts/bitmain/bm1880.dtsi | 28 + drivers/clk/Kconfig | 6 + drivers/clk/Makefile | 1 + drivers/clk/clk-bm1880.c | 970 ++++++++++++++++++ drivers/clk/clk-composite.c | 2 +- drivers/clk/clk-divider.c | 2 +- drivers/clk/clk-fixed-rate.c | 2 +- drivers/clk/clk-gate.c | 2 +- drivers/clk/clk-mux.c | 2 +- drivers/clk/clk.c | 8 + include/dt-bindings/clock/bm1880-clock.h | 82 ++ 14 files changed, 1185 insertions(+), 14 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/bitmain,bm1880-clk.yaml create mode 100644 drivers/clk/clk-bm1880.c create mode 100644 include/dt-bindings/clock/bm1880-clock.h -- 2.17.1
