The MediaTek DPI and DP_INTF function blocks are a sink of the display
subsystem and provides 8-bit RGB/YUV444 or 8/10/10-bit YUV422 pixel data on a
parallel output bus.

description: |
The MediaTek DPI module is typically associated with one of the
following multimedia power domains:
POWER_DOMAIN_DISPLAY
POWER_DOMAIN_VDOSYS
POWER_DOMAIN_MM
The specific power domain used varies depending on the SoC design.
It is recommended to explicitly add the appropriate power domain
property to the DPI node in the device tree.
