29 0x13 vstart
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.
