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.
The existing DT causes the eDP-panel driver to probe an unavailable
panel, resulting in AUX probe timeouts and missing display modes.
Userspace then attempts display commits through the eDP connector,
causing repeated DPU vblank, frame-done, and IRQ timeout errors.
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.

Purwa IoT EVK variants are available with and without an eDP panel.
When the panel is not connected, DP3 is unused, but the base
DTS still describes the eDP panel and display path.
This causes the eDP-panel driver to probe an unavailable panel, resulting
in AUX probe timeouts and missing display modes. Userspace then attempts
display commits through the eDP connector, causing repeated DPU vblank,
frame-done, and IRQ timeout errors.
Move the DP3 and eDP panel specific nodes into an overlay so the base
DTB describes the configuration without the panel, while the overlay
enables eDP panel for boards with the panel connected.
DT overlays cannot remove properties from a node defined in the base
DTB, so keeping the /delete-property/ of #sound-dai-cells in base DTS
where it takes effect.
