CPTS and RGMII has MAIN_PLL3 as their parent which does not have this flag. While RGMII needs this reinitialisation to default frequency to be able to get 250MHz with its divider, CPTS can not get its required 200MHz with its divider. Thus, move CPTS clock parent on J721S2 from MAIN_PLL3_HSDIV1 to MAIN_PLL0_HSDIV6. (Note: even GTC will be moved from MAIN_PLL3 to MAIN_PLL0 in U-Boot side for the same reason) Signed-off-by: Neha Malcom Francis Link: https://lore.kernel.org/r/20230605110443.84568-1-n-francis@ti.com Signed-off-by: Vignesh Raghavendra --- diff --git a/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi b/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi index 12a5b7008aca5..ed79ab3a32718 100644 --- a/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi @@ -1030,6 +1030,8 @@ reg-names = "cpts"; clocks = <&k3_clks 226 5>; clock-names = "cpts"; + assigned-clocks = <&k3_clks 226 5>; /* NAVSS0_CPTS_0_RCLK */ + assigned-clock-parents = <&k3_clks 226 7>; /* MAIN_0_HSDIVOUT6_CLK */ interrupts-extended = <&main_navss_intr 391>; interrupt-names = "cpts"; ti,cpts-periodic-outputs = <6>; diff --git a/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi b/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi index 939cd037a814e..5734c67b6763d 100644 --- a/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721s2-mcu-wakeup.dtsi @@ -525,6 +525,8 @@ reg = <0x0 0x3d000 0x0 0x400>; clocks = <&k3_clks 29 3>; clock-names = "cpts"; + assigned-clocks = <&k3_clks 29 3>; /* CPTS_RFT_CLK */ + assigned-clock-parents = <&k3_clks 29 5>; /* MAIN_0_HSDIVOUT6_CLK */ interrupts-extended = <&gic500 GIC_SPI 858 IRQ_TYPE_LEVEL_HIGH>; interrupt-names = "cpts"; ti,cpts-ext-ts-inputs = <4>;
