+/* 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.
