[PATCH 0/2] arm64: dts: qcom: Add eDP display overlays for hamoa and purwa IoT EVKs

Posted by Anand Tiwari 1 month, 3 weeks ago

Both Hamoa and Purwa IoT EVKs are available in headed and headless
variants. The headed variants use an eDP display panel connected via
the DP3 controller, while the headless variants do not include a
display.

Move the eDP-specific nodes out of the base DTS files into separate
DTBO overlays for each board. This allows the base DTBs to be used
as-is for headless variants, while the composite DTBs enable eDP
support on headed variants.

Is DP3 routed to a connector or is it unused?

It is unused in headless variant.
