How to customize DSI RGB format

[r.tanaka]

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>;

"lcd_dsi_format" has been changed from 0 to 3


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 Frame buffer device information:    Name        :    Address     : 0x57354000    Size        : 4915200    Type        : PACKED PIXELS    Visual      : TRUECOLOR    XPanStep    : 1    YPanStep    : 1    YWrapStep   : 0    LineLength  : 4096    Accelerator : No pine64@pine64:~$

Is there a mistake in how to change the DSI RGB format?

Also, I tryed change to RGB format with reference to the following page.
http://linux-sunxi.org/Fex_Guide#FEX_Description

[sun50i-a64-pine64-plus.dts]

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>; 2139             interrupts = <0x0 0x56 0x104 0x0 0x57 0x104 0x0 0x59 0x104>; 2140             clocks = <0x6a 0x6b 0x6c 0x6d 0x6e>; 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         };

"fb0_format" has been changed from 0 to 5


But, the result did not change.
