CLK == 71.1MHz 的时候,
Tv - Tvd == 23
Th - Thd == 160
542 timing2: timing2 {
543 clock-frequency = <71100000>;
544 hactive = <1280>;
545 vactive = <800>;
546 hback-porch = <75>;
547 hfront-porch = <75>;
548 vback-porch = <13>;
549 vfront-porch = <5>;
550 hsync-len = <10>;
551 vsync-len = <5>;
552 hsync-active = <0>;
553 vsync-active = <0>;
554 de-active = <0>;
555 pixelclk-active = <0>;
556 };
这里 CLK 就填上面的 CLK
hactive vactive 就是分辨率
(hback-porch + hfront-porch + hsync-len) == (Th - Thd)
(vbach-porch + vfront-porch + vsync-len) == (Tv - Tvd)
pixelclk-active 是时钟旋转,1 的时候,时钟旋转,0 不旋转。
