23 /* Some documentation on known sonixb registers:
26 0x10 high nibble red gain low nibble blue gain
27 0x11 low nibble green gain
30 0x15 hsize (hsize = register-value * 16)
31 0x16 vsize (vsize = register-value * 16)
32 0x17 bit 0 toggle compression quality (according to sn9c102 driver)
33 0x18 bit 7 enables compression, bit 4-5 set image down scaling:
34 00 scale 1, 01 scale 1/2, 10, scale 1/4
35 0x19 high-nibble is sensor clock divider, changes exposure on sensors which
36 use a clock generated by the bridge. Some sensors have their own clock.
37 0x1c auto_exposure area (for avg_lum) startx (startx = register-value * 32)
38 0x1d auto_exposure area (for avg_lum) starty (starty = register-value * 32)
39 0x1e auto_exposure area (for avg_lum) stopx (hsize = (0x1e - 0x1c) * 32)
40 0x1f auto_exposure area (for avg_lum) stopy (vsize = (0x1f - 0x1d) * 32)
