Series media: vimc: Add support for multiplanar formats | expand

Commit Message

André Almeida March 27, 2019, 3:17 p.m. UTC
Add multiplanar formats to be exposed to the userspace as
supported formats. Since we don't want to support multiplanar
formats when the driver is in singleplanar mode, we only access
the multiplanar formats array if the multiplanar mode is enabled.

Changes in v2:
- Change line break style
- Add TODO comment
