[PATCH v2 4/6] arm64: dts: imx8mm-phyboard-polis-peb-av-10: split display configuration

Tue Oct 7 01:12:29 PDT 2025
The PEB-AV-10 board can be used with different displays or in audio-only
mode.
Split the device tree overlays to reflect these use cases. To use the
board with the EDT ETML1010G3DRA display, the overlay
imx8mm-phyboard-polis-peb-av-10-etml1010g3dra.dtbo must now be used
instead of imx8mm-phyboard-polis-peb-av-10.dtbo.
