Part Number: AM3354
Tool/software: Linux
Hi,
We are using a TFT LCD (controller: HX8264-D) with DE mode (instead of Hsync/Vsync mode) with custom board using AM3354 processor (TI SDK 03.03, Kernel: 4.4.41).
We are unable to find driver details in .dts file to set the parameters for DE mode (Ex: DE mode blanking for horizontal, DE mode blanking for vertical, minimum DE setup/hold time etc.)
Can you kindly suggest how to modify the am335x-evm.dts file to support DE mode ?
Note: Currently, the dts file supports for HSYNC/VSYNC mode as mentioned below (Need to change it to DE mode, please find attached image file for parameter sample of DE mode at the end of this post):
Current DTS:
panel {
compatible = "ti,tilcdc,panel";
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&lcd_pins_s0>;
panel-info {
ac-bias = <255>;
ac-bias-intrpt = <0>;
dma-burst-sz = <16>;
bpp = <24>;
fdd = <0x80>;
sync-edge = <0>;
sync-ctrl = <1>;
raster-order = <0>;
fifo-th = <0>;
};
display-timings {
native-mode = <&timing0>;
timing0: 800x480p62 {
clock-frequency = <30000000>;
hactive = <800>;
vactive = <480>;
hfront-porch = <40>;
hback-porch = <88>;
hsync-len = <48>;
vback-porch = <32>;
vfront-porch = <13>;
vsync-len = <3>;
hsync-active = <1>;
vsync-active = <1>;
};
};
};
Best Regards,
