/* Some documentation on known sonixb registers:
Reg Use
sn9c101 / sn9c102:
0x10 high nibble red gain low nibble blue gain
0x11 low nibble green gain
sn9c103:
0x05 red gain 0-127
0x06 blue gain 0-127
0x07 green gain 0-127
all:
0x08-0x0f i2c / 3wire registers
0x12 hstart
0x13 vstart
0x15 hsize (hsize = register-value * 16)
0x16 vsize (vsize = register-value * 16)
0x17 bit 0 toggle compression quality (according to sn9c102 driver)
0x18 bit 7 enables compression, bit 4-5 set image down scaling:
00 scale 1, 01 scale 1/2, 10, scale 1/4
0x19 high-nibble is sensor clock divider, changes exposure on sensors which
use a clock generated by the bridge. Some sensors have their own clock.
0x1c auto_exposure area (for avg_lum) startx (startx = register-value * 32)
0x1d auto_exposure area (for avg_lum) starty (starty = register-value * 32)
0x1e auto_exposure area (for avg_lum) stopx (hsize = (0x1e
