How to customize DSI RGB format - r.tanaka - 08-28-2018
Hi
I would like to change the DSI format to RGB565.
Therefore, fix the following setting values from DTS.
[sun50i-a64-pine64-plus.dts]
Code:
2182 lcd_dsi_if = <0x2>;
2183 lcd_dsi_lane = <0x4>;
2184 lcd_dsi_format = <0x3>;
2185 lcd_dsi_eotp = <0x0>;
2186 lcd_dsi_vc = <0x0>;
2187 lcd_dsi_te = <0x0>;But, the RGB format of DSI was not changed.
I confirmed with the fbset command.
Code:
pine64@pine64:~$ fbset -i
mode "1024x600-80"
# D: 55.002 MHz, H: 97.178 kHz, V: 79.981 Hz
geometry 1024 600 1024 1200 32
timings 18181 16 -478 4 610 4 1
rgba 8/16,8/8,8/0,8/24
endmode

pine64@pine64:~$Is there a mistake in how to change the DSI RGB format?

Code:
2136 disp@01000000 {
2137 compatible = "allwinner,sun50i-disp";
2138 reg = <0x0 0x1000000 0x0 0x300000 0x0 0x1c0c000 0x0 0x7fc 0x0 0x1c0d000 0x0 0x7fc 0x0 0x1ca0000 0x0 0x10fc>;

2141 status = "okay";
2142 device_type = "disp";
2143 disp_init_enable = <0x1>;
2144 disp_mode = <0x0>;
2145 screen0_output_type = <0x3>;
2146 screen0_output_mode = <0x5>;
2147 screen1_output_type = <0x1>;
2148 screen1_output_mode = <0x5>;
2149 fb0_format = <0x5>;
2150 fb0_width = <0x0>;
2151 fb0_height = <0x0>;
2152 fb1_format = <0x0>;
2153 fb1_width = <0x0>;
2154 fb1_height = <0x0>;
2155 };But, the result did not change.
