Subject: dt-bindings: display: allwinner: Add DE33 planes
|
|
|
|
Allwinner Display Engine 3.3 contains planes, which are shared resources
|
|
between all mixers present in SoC. They can be assigned to specific
|
|
mixer by using registers which reside in display clocks MMIO.
|
|
|
|
Add a binding for them.

+description: |
|
|
+ Display Engine 3.3 planes are independent of mixers, contrary to
|
|
+ previous generations of Display Engine. Planes can be assigned to
|
|
+ mixers independently and even dynamically during runtime.
