Subject: media: sun6i-csi: capture: Use subdev operation to access bridge
|
|
format
|
|
|
|
Replace the sun6i_csi_bridge helper functions sun6i_csi_bridge_format()
|
|
and sun6i_csi_bridge_dimensions() that access the bridge fields from the
|
|
capture side with usage of the subdev .get_fmt() operation. This
|
|
decouples the bridge and capture side better by using abstractions
|
|
provided by the V4L2 subdev API, and prepares for usage of the subdev
|
|
active state in the bridge.
|
|
|
|
The sun6i_csi_bridge_dimensions() helper is now unused and is removed.
|
|
The sun6i_csi_bridge_format() helper will be removed in a subsequent
|
|
change.
|
|
