commit 235fef6c7fd341026eee90cc546e6e8ff8b2c315 upstream.

[Why]
MALL size available can vary for different SKUs.
Use num_chans read from VBIOS to determine the available MALL size we can use

[How]
Define max_chans for DCN32 and DCN321.
If num_chans is max_chans, then return max_chans as we can access the
 entire MALL space.
Otherwise, define avail_chans as the number of available channels we are
 allowed instead.
Return corresponding number of channels back and use this to calculate
 available MALL size.

There is an AGC pre-gain in register 0x3a13, expressed as a 6-bit value (plus an enable bit in bit 6). The driver hardcodes it to 0x43, which one application note states is equal to x1.047. The documentation also states that 0x40 is equel to x1.000. The pre-gain thus seems to be expressed as in 1/64 increments, and thus ranges from x1.00 to x1.984. What the pre-gain does is however unspecified. There is then an AGC gain limit, in registers 0x3a18 and 0x3a19, expressed as a 10-bit "real gain format" value. One application note sets it to 0x00f8 and states it is equal to x15.5, so it appears to be expressed in 1/16 increments, up to x63.9375. The manual gain is stored in registers 0x350a and 0x350b, also as a 10-bit "real gain format" value. It is documented in the application note as a Q6.4 values, up to x63.9375. One version of the datasheet indicates that the sensor supports a digital gain: The OV5640 supports 1/2/4 digital gain. Normally, the gain is controlled automatically by the automatic gain control (AGC) block. It isn't clear how that would be controlled manually. There appears to be no indication regarding whether the gain controlled through registers 0x350a and 0x350b is an analogue gain only or also includes digital gain. The words "real gain" don't necessarily mean "combined analogue and digital gains". Some OmniVision sensors (such as the OV8858) are documented as supoprting different formats for the gain values, selectable through a register bit, and they are called "real gain format" and "sensor gain format". For that sensor, we have (one of) the gain registers documented as 0x3503[2]=0, gain[7:0] is real gain format, where low 4 bits are fraction bits, for example, 0x10 is 1x gain, 0x28 is 2.5x gain If 0x3503[2]=1, gain[7:0] is sensor gain format, gain[7:4] is coarse gain, 00000: 1x, 00001: 2x, 00011: 4x, 00111: 8x, gain[7] is 1, gain[3:0] is fine gain. For example, 0x10 is 1x gain, 0x30 is 2x gain, 0x70 is 4x gain (The second part of the text makes little sense) "Real gain" may thus refer to the combination of the coarse and fine analogue gains as a single value. The OV5640 0x350a and 0x350b registers thus appear to control analogue gain. The driver incorrectly uses V4L2_CID_GAIN as V4L2 has a specific control for analogue gain, V4L2_CID_ANALOGUE_GAIN. Use it. If registers 0x350a and 0x350b are later found to control digital gain as well, the driver could then restrict the range of the analogue gain control value to lower than x64 and add a separate digital gain control.

digital gain:

  The OV5640 supports 1/2/4 digital gain. Normally, the gain is
  controlled automatically by the automatic gain control (AGC) block.

It isn't clear how that would be controlled manually.

There appears to be no indication regarding whether the gain controlled
through registers 0x350a and 0x350b is an analogue gain only or also
includes digital gain. The words "real gain" don't necessarily mean
"combined analogue and digital gains". Some OmniVision sensors (such as
the OV8858) are documented as supoprting different formats for the gain
values, selectable through a register bit, and they are called "real
gain format" and "sensor gain format". For that sensor, we have (one of)
the gain registers documented as

  0x3503[2]=0, gain[7:0] is real gain format, where low 4 bits are
  fraction bits, for example, 0x10 is 1x gain, 0x28 is 2.5x gain

  If 0x3503[2]=1, gain[7:0] is sensor gain format, gain[7:4] is coarse
  gain, 00000: 1x, 00001: 2x, 00011: 4x, 00111: 8x, gain[7] is 1,
  gain[3:0] is fine gain. For example, 0x10 is 1x gain, 0x30 is 2x gain,
  0x70 is 4x gain

(The second part of the text makes little sense)

"Real gain" may thus refer to the combination of the coarse and fine
analogue gains as a single value.

The OV5640 0x350a and 0x350b registers thus appear to control analogue
gain. The driver incorrectly uses V4L2_CID_GAIN as V4L2 has a specific
control for analogue gain, V4L2_CID_ANALOGUE_GAIN. Use it.

If registers 0x350a and 0x350b are later found to control digital gain
as well, the driver could then restrict the range of the analogue gain
control value to lower than x64 and add a separate digital gain control.
