Hi,

You need to share more information for us to help you. Could you:

  1. In the kernel bootargs, add “debug drm.debug=0x1f”
  2. Share the dtsi file where’ you’ve added the device
  3. Share some info about the release on which you’re trying this out

Thanks

Hi,

The DT looks okay. From the logs, it doesn’t look like anyone is trying to enable the display. You would need either fb console, or run X server so that the panel is enabled. Once that happens, the drm_panel’s enable op should be called, which would then enable the DSI host side. You should see logs from funcs like dsi_mgr_bridge_pre_enable and msm_dsi_host_power_on.

After enabling fb console, we are able to see logs from dsi_mgr_bridge_pre_enable and msm_dsi_host_power_on. But still, nothing was seen on DSI panel.
Attached logs here,

Hi,

The DT entry has specified 4 data lanes for the panel. But from the panel driver[1], it looks like it supports only 2 lanes.

Also, the panel driver seems to control only the reset gpio. All the other gpios (backlight, pwr-en, pwm) that you have specifed in the DT are not controlled by the driver. Please see the panel’s DT bindings to see in what format you have to provide backlight and panel info.

From the logs, it looks like the panel is successfully consuming the DCS commands sent to it. But since you aren’t passing the backlight/pwm info properly via DT, you might not be seeing anything on the screen. As a short cut, you can modify the panel driver so that it sets the desired gpio that enables the backlight. Please refer to the panel’s data sheet to ensure you’re following the right power-on sequences too.
