It introduces three clock controllers: - SCMI clock controller: these clocks are managed by the SCP and handled through SCMI. - PLL clock controller. - peripheral clock controller. Changes v5 since v4 at [4]: - rename rtc and cec dualdiv clocks - rename dsp clocks - rename anakin clocks - rename fdiv2_divn to 25m and fix its parent - add flag for T7_COMP_GATE - use T7_COMP_SEL/DIV/GATE to define glitch clocks - add CLK_SET_RATE_NO_REPARENT for t7_eth_rmii_sel and rtc - move module_platform_driver after clock driver
Looks good to me, just a few minor comments. It is too late of this cycle. Please check the comments and re-send on the next -rc1
Changes v4 since v3 at [3]: - drop amlogic_t7_pll_probe, use meson_clkc_mmio_probe instead - add CLK_DIVIDER_MAX_AT_ZERO for pcie_pll_od clk - add frac for hifi_dco_pll_dco - add l_detect for mclk_pll_dco - drop v3 5/6 patch, and use MESON_PCLK - drop SPI_PWM_CLK_XX macro and use MESON_COMP_XX - drop the register's prefix Changes v3 since v2 at [2]: - update T7 PLL YAML - add 't7_' prefix for t7 clock name and variable in t7-pll.c and t7-peripherals.c - correct v1 patch link - add new macro MESON_PCLK_V2 - update the driver,header,yaml file license Changes v2 since v1 at [1]: - add CLK_MESON import - add const for clkc_regmap_config in PLL driver - fix eth_rmii_sel parent - update T7 PLL YAML file [1]: https://lore.kernel.org/all/20241231060047.2298871-1-jian.hu@amlogic.com (local) [2]: https://lore.kernel.org/all/20250108094025.2664201-1-jian.hu@amlogic.com (local) [3]: https://lore.kernel.org/all/20250509074825.1933254-1-jian.hu@amlogic.com (local) [4]: https://lore.kernel.org/all/20251030094345.2571222-1-jian.hu@amlogic.com (local) Jian Hu (5): dt-bindings: clock: add Amlogic T7 PLL clock controller dt-bindings: clock: add Amlogic T7 SCMI clock controller dt-bindings: clock: add Amlogic T7 peripherals clock controller clk: meson: t7: add support for the T7 SoC PLL clock clk: meson: t7: add t7 clock peripherals controller driver .../clock/amlogic,t7-peripherals-clkc.yaml | 116 ++ .../bindings/clock/amlogic,t7-pll-clkc.yaml | 114 ++ drivers/clk/meson/Kconfig | 27 + drivers/clk/meson/Makefile | 2 + drivers/clk/meson/t7-peripherals.c | 1266 +++++++++++++++++ drivers/clk/meson/t7-pll.c | 1068 ++++++++++++++ .../clock/amlogic,t7-peripherals-clkc.h | 228 +++ .../dt-bindings/clock/amlogic,t7-pll-clkc.h | 56 + include/dt-bindings/clock/amlogic,t7-scmi.h | 47 + 9 files changed, 2924 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/amlogic,t7-peripherals-clkc.yaml create mode 100644 Documentation/devicetree/bindings/clock/amlogic,t7-pll-clkc.yaml create mode 100644 drivers/clk/meson/t7-peripherals.c create mode 100644 drivers/clk/meson/t7-pll.c create mode 100644 include/dt-bindings/clock/amlogic,t7-peripherals-clkc.h create mode 100644 include/dt-bindings/clock/amlogic,t7-pll-clkc.h create mode 100644 include/dt-bindings/clock/amlogic,t7-scmi.h
