How to setting multiple displays

Hello,

Someone please help me.

We are trying to use the following dual display,

1. LVDS(LCD)

2. HDMI LVDS (LCD) displays normally.

When connecting HDMI, I want LVDS+HDMI dual display output.

The BSP and CPU information we are using is below.

BSP : Android 11.0.0_2.6.0 (Linux 5.10.72 kernel)

CPU : IMX8MP

The current problem is that if we disable the lcd (LVDS) panel driver, HDMI output is possible,

but if we enable the lcd (LVDS) panel driver, There is no HDMI output, so dual display is not possible.

I would like to know the device tree file and any additional modifications required for dual display output. Attached is our device tree file that we are using for LVDS (LCD) output.

BR,
Ryan
