This change is incompatible with older kernels because it requires the clock controller driver, but I think that's acceptable because WPCM450 support is generally still in an early phase. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@xxxxxxx> --- It's probably best to delay merging of this patch until after the driver is merged; I'm including it here for review, and in case someone want's to set up a shared branch between the clock and devicetree parts. v10: - Reintroducing this patch as part of the clock/reset controller series --- .../arm/boot/dts/nuvoton/nuvoton-wpcm450.dtsi | 22 +++++++++---------- 1 file changed, 10 insertions(+), 12 deletions(-) diff --git a/arch/arm/boot/dts/nuvoton/nuvoton-wpcm450.dtsi b/arch/arm/boot/dts/nuvoton/nuvoton-wpcm450.dtsi index 9dfdd8f67319d3..7e3ea8b31151b3 100644 --- a/arch/arm/boot/dts/nuvoton/nuvoton-wpcm450.dtsi +++ b/arch/arm/boot/dts/nuvoton/nuvoton-wpcm450.dtsi @@ -2,6 +2,7 @@ // Copyright 2021 Jonathan Neuschäfer #include <dt-bindings/interrupt-controller/irq.h> +#include <dt-bindings/clock/nuvoton,wpcm450-clk.h> / { compatible = "nuvoton,wpcm450"; @@ -30,13 +31,6 @@ cpu@0 { }; }; - clk24m: clock-24mhz { - /* 24 MHz dummy clock */ - compatible = "fixed-clock"; - clock-frequency = <24000000>; - #clock-cells = <0>; - }; - refclk: clock-48mhz { /* 48 MHz reference oscillator */ compatible = "fixed-clock"; @@ -70,7 +64,7 @@ serial0: serial@b8000000 { reg = <0xb8000000 0x20>; reg-shift = <2>; interrupts = <7 IRQ_TYPE_LEVEL_HIGH>; - clocks = <&clk24m>; + clocks = <&clk WPCM450_CLK_UART0>; pinctrl-names = "default"; pinctrl-0 = <&bsp_pins>; status = "disabled"; @@ -81,7 +75,7 @@ serial1: serial@b8000100 { reg = <0xb8000100 0x20>; reg-shift = <2>; interrupts = <8 IRQ_TYPE_LEVEL_HIGH>; - clocks = <&clk24m>; + clocks = <&clk WPCM450_CLK_UART1>; status = "disabled"; }; @@ -89,14 +83,18 @@ timer0: timer@b8001000 { compatible = "nuvoton,wpcm450-timer"; interrupts = <12 IRQ_TYPE_LEVEL_HIGH>; reg = <0xb8001000 0x1c>; - clocks = <&clk24m>; + clocks = <&clk WPCM450_CLK_TIMER0>, + <&clk WPCM450_CLK_TIMER1>, + <&clk WPCM450_CLK_TIMER2>, + <&clk WPCM450_CLK_TIMER3>, + <&clk WPCM450_CLK_TIMER4>; }; watchdog0: watchdog@b800101c { compatible = "nuvoton,wpcm450-wdt"; interrupts = <1 IRQ_TYPE_LEVEL_HIGH>; reg = <0xb800101c 0x4>; - clocks = <&clk24m>; + clocks = <&clk WPCM450_CLK_WDT>; }; aic: interrupt-controller@b8002000 { @@ -480,7 +478,7 @@ fiu: spi-controller@c8000000 { #size-cells = <0>; reg = <0xc8000000 0x1000>, <0xc0000000 0x4000000>; reg-names = "control", "memory"; - clocks = <&clk 0>; + clocks = <&clk WPCM450_CLK_FIU>; nuvoton,shm = <&shm>; status = "disabled"; }; -- 2.43.0
