| sn9c103: |
| 0x05 red gain 0-127 |

| 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. |
