Part Number: DRA76P
Tool/software: Linux
Already this topic is discussed in following thread :
https://e2e.ti.com/support/processors/f/791/t/719730
Here, I did according to last suggestion that need to assign unique alias to all display to detect like:
/ {
aliases {
display0= &lcd_hdmi;
display1 = &fpd_disp;
display2 = &hdmi0;
};
};
Now,
1. fpd is working properly and HDMI also working properly but on fake lcd the mirror image is coming of HDMI display.
2. Also, in modetest command only 2 crtcs are visible one for fpd and another for HDMI.
Please refer attached final dts file, if I am wrong or I didn't explain properly.
#include "dra76-evm-fake-lcd.dts"
#include "dra7x-evm-fpd-auo-g101evn01.0.dtsi"
/ {
aliases {
display0 = &lcd_hdmi;
display1 = &fpd_disp;
display2 = &hdmi0;
};
};
&dss {
ports {
status = "ok";
};
};
&disp_ser {
status = "ok";
ranges = <0x0 0x2d>;
};
/* Tie the end points of DSS and FPDLink together */
&fpd_in {
remote-endpoint = <&dpi_out3>;
};
&dpi_out3 {
remote-endpoint = <&fpd_in>;
};
&lcd_fpd {
status = "ok";
};
/* U21 on the EVM */
/* gpmc_ad_vid_s0: high: GPMC , low: VOUT3 */
&pcf_gpio_21 {
p0 {
gpio-hog;
gpios = <0 GPIO_ACTIVE_HIGH>;
output-low;
line-name = "gpmc_ad_vid_s0";
};
};
/* U110 on the EVM. For Rev A boards */
/*
&pcf_hdmi {
p11 {
gpio-hog;
gpios = <11 GPIO_ACTIVE_HIGH>;
output-low;
line-name = "disp1_vpoc_onn";
};
};
*/
/* For supplying power to the display via FPDLink */
&gpio2 {
p2 {
gpio-hog;
gpios = <2 GPIO_ACTIVE_HIGH>;
output-low;
line-name = "disp1_vpoc_onn";
};
};
