Hi:
Now we want to change to use DRA722 VIN2A_XX as VOUT2 to connect LCD, but actually there is no output in any VOUT2 pins.
But we found that DRA745 VOUT3 can work correctly.
And this question is same as e2e.ti.com/.../577167
1) mux_data.h
configure VIN2A_XX to VOUT2
omapconf dump 0x4a003554 0x4a0035C4

2) dra7.dts
&dss {
ports {
#address-cells = <1>;
#size-cells = <0>;
port@lcd2 {
reg = <1>;
lvds_out: endpoint {
remote-endpoint = <&lvds_in>;
data-lines = <24>;
};
};
};
};
Thanks.
