[PATCH v2 06/15] staging: mmal_vchiq: Add image formats to be used by bcm2835-isp

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

 



From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>

The bcm2835-isp supports Bayer, so add in the encodings for them.
Also, Add support for monochrome image formats in the various MIPI
packings.
