Sorry for the inconvenience and please refer to this, - dt-binding changes - relicense binding headers as GPL-2.0-only OR MIT - use gapless integers starting from 0 for binding IDs - make input clocks essential, add corresponding description - rename the input clock that is generated by phy module as "gmac0" - style fixes - driver changes - format in the common Rockchip driver style - drop initializing code of the reset controller, as it'll not be supported in this series > > Yao Zi (5): > dt-bindings: clock: Document clock and reset unit of RK3528 > clk: rockchip: Add PLL flag ROCKCHIP_PLL_FIXED_MODE > clk: rockchip: Add clock controller driver for RK3528 SoC > arm64: dts: rockchip: Add clock generators for RK3528 SoC > arm64: dts: rockchip: Add UART clocks for RK3528 SoC > > .../bindings/clock/rockchip,rk3528-cru.yaml | 67 + > arch/arm64/boot/dts/rockchip/rk3528.dtsi | 68 +- > drivers/clk/rockchip/Kconfig | 7 + > drivers/clk/rockchip/Makefile | 1 + > drivers/clk/rockchip/clk-pll.c | 10 +- > drivers/clk/rockchip/clk-rk3528.c | 1114 +++++++++++++++++ > drivers/clk/rockchip/clk.h | 22 + > .../dt-bindings/clock/rockchip,rk3528-cru.h | 453 +++++++ > .../dt-bindings/reset/rockchip,rk3528-cru.h | 241 ++++ > 9 files changed, 1978 insertions(+), 5 deletions(-) > create mode 100644 Documentation/devicetree/bindings/clock/rockchip,rk3528-cru.yaml > create mode 100644 drivers/clk/rockchip/clk-rk3528.c > create mode 100644 include/dt-bindings/clock/rockchip,rk3528-cru.h > create mode 100644 include/dt-bindings/reset/rockchip,rk3528-cru.h > > -- > 2.47.1 >
