s5k3l6xx: RAW10 support
Using 10-bit pixel depth improves picture quality in dark areas a lot. Currently the driver is limited to RAW8 only.
I have quickly hacked in RAW10 for testing - sebastian.krzyszkowiak/linux-next@565058e0 - but only 1052x780 works this way. 2104x1560 results in garbled image, while 4208x3120 does not give any image at all.
