support new MIPI DSI panel

Hello,

I have to attach MIPI DSI display to iMX6QP reference board (MCIMX6QP -SBP) and run Linux on this display.

I’am using:

- iMX6QP reference board (with MIPI connector)

- MIPI DSI panel TRULY (HD0499K00059). It have resolution 720x1080.

- NXP Linux BSP release (Linux kernel revision 4.9) from Yocto 2.2 (Release L4.9.11_1.0.0-ga)

As I know, MIPI DSI support exist in the current kernel by driver and main my task is make configure for new HW. Am I right?

My current plan:

1) describe new MIPI_DSI panel in platform device tree files

2) remove HDMI and LVDS displays from supported drivers in kernel configuration. Rebuild image.

3) configure bootargs for new display usage by kernel.

Did I miss something?

What more details have I read to better understood? Links are preferred.

Display panel also contain touch, but now it’s postponed to make it work.

Hi Alexey

one can look at sect.6.4 MIPI DSI attached Linux Manual and make new driver

based on existing, use appropriate kernel boot parameter

from Table 10. Common kernel boot parameters Release Notes,

check fb_videomode truly_lcd_modedb[] in linux/drivers/video/fbdev/mxc/mxcfb_hx8363_wvga.c

More examples can be found on
