/* Some documentation about various registers as determined by trial and error.
   When the register addresses differ between the 7202 and the 7311 the 2
   different addresses are written as 7302addr/7311addr, when one of the 2
   addresses is a - sign that register description is not valid for the
   matching IC.

   Register page 1:

   Address	Description
   -/0x08	Unknown compressor related, must always be 8 except when not
		in 640x480 resolution and page 4 reg 2 <= 3 then set it to 9 !
   -/0x1b	Auto white balance related, bit 0 is AWB enable (inverted)
		bits 345 seem to toggle per color gains on/off (inverted)
   0x78		Global control, bit 6 controls the LED (inverted)
   -/0x80	JPEG compression ratio ? Best not touched

   Register page 3/4:

   Address	Description
   0x02		Clock divider 2-63, fps =~ 60 / val. Must be a multiple of 3 on
		the 7302, so one of 3, 6, 9, ..., except when between 6 and 12?
   -/0x0f	Master gain 1-245, low value = high gain
   0x10/-	Master gain 0-31
   -/0x10	Another gain 0-15, limited influence (1-2x gain I guess)
   0x21		Bitfield: 0-1 unused, 2-3 vflip/hflip, 4-5 unknown, 6-7 unused
   -/0x27	Seems to toggle various gains on / off, Setting bit 7 seems to
		completely disable the analog amplification block. Set to 0x68
		for max gain, 0x14 for minimal gain.

   The registers are accessed in the following functions:
