[PATCH v2 4/5] media: atmel-isi: setup YCC_SWAP correctly when using preview path Josh Wu <josh.wu@atmel.com> - 2015-11-03 06:50 +0100

| Message-ID | <qqCDL-6X8-7@gated-at.bofh.it> |
The preview path only can convert UYVY format to RGB data.
To make preview path work correctly, we need to set up YCC_SWAP
according to sensor output and convert them to UYVY.

Changes in v2:
- remove cfg2_yuv_swap for rgb format
- correct the comment style
