Subject: [PATCH 424/828] dt-bindings: display: vc4: Add phandle to the
|
2021-11-24 17:32:01 +00:00
|
|
|
firmware
|
|
|
|
|
|
|
|
|
|
The vc4 driver will need to tell the firmware that it takes over the
|
|
|
|
|
display for the firmware to free its resources (lower the clock, free
|
|
|
|
|
some memory, etc.)
|
|
|
|
|
|
|
|
|
|
Let's add an optional phandle to our firmware node.
