+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.
