清问一下uboot设置的这个参数和dts设置的这里有什么不一样的吗?
&ldb {
status = "okay";
dual-mode = <1>;
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
status = "okay";
display-timings {
native-mode = <&timing0>;
timing0: hsd100pxn1 {
clock-frequency = <65000000>;
hactive = <1280>;
vactive = <800>;
hback-porch = <20>;
hfront-porch = <20>;
vback-porch = <4>;
vfront-porch = <4>;
hsync-len = <10>;
vsync-len = <4>;
};
};
};
lvds-channel@1 {
fsl,data-mapping = "spwg";
fsl,data-width = <18>;
primary;
status = "okay";
display-timings {
native-mode = <&timing1>;
timing1: hsd100pxn1 {
clock-frequency = <65000000>;
hactive = <1024>;
vactive = <768>;
hback-porch = <220>;
hfront-porch = <40>;
vback-porch = <21>;
vfront-porch = <7>;
hsync-len = <60>;
vsync-len = <10>;
};
};
};
};
前者是针对软件显示的分辨率后者是对应驱动实际显示屏的参数? |
