"[PATCH v2 4/4] drm/bridge: anx7625: Use DPI bus type"
|
||
|
|
|
||
|
|
thanks to wens from the #linux-mediatek irc for pointing me to this patch
|
||
|
|
|
||
|
|
As V4L2_FWNODE_BUS_TYPE_PARALLEL not properly descript for DPI
|
||
|
|
interface, this patch use new defined V4L2_FWNODE_BUS_TYPE_DPI for it.
|
||
|
|
|
||
|

Fixes: fd0310b6fe7d ("drm/bridge: anx7625: add MIPI DPI input feature")
