[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andy Yan <andy.yan@xxxxxxxxxxxxxx>

The vop2 on rk3588 is similar to which on rk356x
but with 4 video ports and need to reference
more grf modules.

Signed-off-by: Andy Yan <andy.yan@xxxxxxxxxxxxxx>

Changes in v3:
- constrain properties in allOf:if:then
- some description updates
