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

67 The MediaTek DPI module is typically associated with one of the
68 following multimedia power domains:
69 POWER_DOMAIN_DISPLAY
70 POWER_DOMAIN_VDOSYS
71 POWER_DOMAIN_MM
72 The specific power domain used varies depending on the SoC design.
73
74 It is recommended to explicitly add the appropriate power domain
75 property to the DPI node in the device tree.
