[PATCH RFC 1/3] [media] s5c73m3: Add driver

Andrzej Hajda
2012-11-23T15:23:03Z

Add driver for S5C73M3 image sensor. The driver exposes the sensor as
two subdevs: pure sensor and output interface. Two subdev architecture
supports interleaved UYVY/JPEG image format with separate frame size
for both sub-formats, there is a spearate pad for each sub-format.
