This means the clock rate of PLL_V0PLL can be adjusted according to the dclk rate of relevant VP. It is typically assigned as the dclk source of a specific VP when the clock of relevant display mode is unusual, such as the eDP panel 'lg,lp079qx1-sp0v' paired with RK3588S EVB1, which has a clock rate of 202.02MHz. Signed-off-by: Damon Ding --- Changes in v2: - Remove brightness-levels and default-brightness-level properties in backlight node. - Add the detail DT changes to commit message. Changes in v3: - Use aux-bus instead of platform bus for edp-panel. Changes in v4: - Add comments related to the use of panel compatible "lg,lp079qx1-sp0v" in the commit message. Changes in v5: - Use "edp-panel" instead of "lg,lp079qx1-sp0v" - Remove unnecessary comments in commit message - Assign the parent of DCLK_VOP2_SRC to PLL_V0PLL Changes in v6: - Add PLL_V0PLL related descriptions in commit message --- .../boot/dts/rockchip/rk3588s-evb1-v10.dts | 54 +++++++++++++++++++ 1 file changed, 54 insertions(+) diff --git a/arch/arm64/boot/dts/rockchip/rk3588s-evb1-v10.dts b/arch/arm64/boot/dts/rockchip/rk3588s-evb1-v10.dts index bc4077575beb..a8c151b41e21 100644 --- a/arch/arm64/boot/dts/rockchip/rk3588s-evb1-v10.dts +++ b/arch/arm64/boot/dts/rockchip/rk3588s-evb1-v10.dts @@ -9,6 +9,7 @@ #include #include #include +#include #include #include "rk3588s.dtsi" @@ -238,6 +239,41 @@ &combphy2_psu { status = "okay"; }; +&edp0 { + force-hpd; + status = "okay"; + + aux-bus { + panel { + compatible = "edp-panel"; + backlight = <&backlight>; + power-supply = <&vcc3v3_lcd_edp>; + + port { + panel_in_edp: endpoint { + remote-endpoint = <&edp_out_panel>; + }; + }; + }; + }; +}; + +&edp0_in { + edp0_in_vp2: endpoint { + remote-endpoint = <&vp2_out_edp0>; + }; +}; + +&edp0_out { + edp_out_panel: endpoint { + remote-endpoint = <&panel_in_edp>; + }; +}; + +&hdptxphy0 { + status = "okay"; +}; + &i2c3 { status = "okay"; @@ -399,6 +435,7 @@ usbc0_int: usbc0-int { }; &pwm12 { + pinctrl-0 = <&pwm12m1_pins>; status = "okay"; }; @@ -1168,3 +1205,20 @@ usbdp_phy0_dp_altmode_mux: endpoint@1 { }; }; }; + +&vop_mmu { + status = "okay"; +}; + +&vop { + assigned-clocks = <&cru DCLK_VOP2_SRC>; + assigned-clock-parents = <&cru PLL_V0PLL>; + status = "okay"; +}; + +&vp2 { + vp2_out_edp0: endpoint@ROCKCHIP_VOP2_EP_EDP0 { + reg = ; + remote-endpoint = <&edp0_in_vp2>; + }; +};
