This series will enable preview path support in atmel-isi. Which can
make atmel-isi convert the YUV format (from sensor) to RGB565 format.

Changes in v2:
- remove the duplicated variable: cfg2_yuv_swap.
- correct the comment style
- According to Guennadi's suggestion, remove the is_output_rgb() function
  which only used once. Also move the code into the for loop.

Josh Wu (5):
  media: atmel-isi: correct yuv swap according to different sensor
    outputs
  media: atmel-isi: prepare for the support of preview path
  media: atmel-isi: add code to setup correct resolution for preview
    path
  media: atmel-isi: setup YCC_SWAP correctly when using preview path
  media: atmel-isi: support RGB565 output when sensor output YUV formats
