280x12 hstart
290x13 vstart
300x15 hsize (hsize = register-value * 16)
310x16 vsize (vsize = register-value * 16)
320x17 bit 0 toggle compression quality (according to sn9c102 driver)
330x18 bit 7 enables compression, bit 4-5 set image down scaling:
34 00 scale 1, 01 scale 1/2, 10, scale 1/4
350x19 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.
370x1c auto_exposure area (for avg_lum) startx (startx = register-value * 32)
380x1d auto_exposure area (for avg_lum) starty (starty = register-value * 32)
