With the binned modes, there is little point in faithfully
reproducing the horizontal line length of 5352 pixels on the CSI2
bus, and the FIFO between the pixel array and MIPI serialiser
allows us to remove that dependency.
Allow the pixel array to run with the normal settings, with the MIPI
serialiser at half the rate. This requires some additional
information for the link frequency to pixel rate function that
needs to be added to the configuration tables.

The output image is defined as being 4208x3118 pixels in size.
Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
3119 lines total.
The datasheet lists a requirement for Y_ADD_STA to be a multiple
of a power of 2 depending on binning/scaling mode (2 for full pixel,
4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
for (x4-bin)+(x2-subsample)).
(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
The current configuration for the full res modes breaks that second
requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
the same field of view as that then breaks the first requirement.
For the binned modes, they are worse off as 3118 is not a multiple of
4.
Increase the main mode to 4208x3120 so that it is the same FOV as the
binned modes, with Y_ADD_STA at 0.
Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
sensor requirements.
This does change the Bayer order as the default configuration is for
H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
and this patch has changed Y_STA_END.

Currently we have the following algorithm to calculate what value should be
written to the exposure control of imx412.
lpfr = imx412->vblank + imx412->cur_mode->height;
shutter = lpfr - exposure;
The 'shutter' value is given to IMX412_REG_EXPOSURE_CIT however, the above
algorithm will result in the value given to IMX412_REG_EXPOSURE_CIT
decreasing as the requested exposure value from user-space goes up.
e.g.
[ 2255.713989] imx412 20-001a: Received exp 1608, analog gain 0
[ 2255.714002] imx412 20-001a: Set exp 1608, analog gain 0, shutter 1938, lpfr 3546
[ 2256.302770] imx412 20-001a: Received exp 2586, analog gain 100
[ 2256.302800] imx412 20-001a: Set exp 2586, analog gain 100, shutter 960, lpfr 3546
[ 2256.753755] imx412 20-001a: Received exp 3524, analog gain 110
[ 2256.753772] imx412 20-001a: Set exp 3524, analog gain 110, shutter 22, lpfr 3546
This behaviour results in the image having less exposure as the requested
exposure value from user-space increases.
Other sensor drivers such as ov5675, imx218, hid556 and others take the
requested exposure value and use the value directly.
Take the example of the above cited sensor drivers and directly apply the
requested exposure value from user-space. The 'lpfr' variable still
functions as before but the 'shutter' variable can be dispensed with as a
result.
Once done a similar run of the test application requesting higher exposure
looks like this, with 'exp' written directly to the sensor.
[ 133.207884] imx412 20-001a: Received exp 1608, analog gain 0
[ 133.207899] imx412 20-001a: Set exp 1608, analog gain 0, lpfr 3546
[ 133.905309] imx412 20-001a: Received exp 2844, analog gain 100
[ 133.905344] imx412 20-001a: Set exp 2844, analog gain 100, lpfr 3546
[ 134.241705] imx412 20-001a: Received exp 3524, analog gain 110
[ 134.241775] imx412 20-001a: Set exp 3524, analog gain 110, lpfr 3546
The result is then setting the sensor exposure to lower values results in
darker, less exposure images and vice versa with higher exposure values.

Before this commit on probe() the driver would do:
reset=1 // from probe() calling gpiod_get(GPIOD_OUT_HIGH)
reset=0 // from resume()
msleep(20) // from resume()
So if reset was 0 before getting the GPIO the reset line would only be
driven high for a very short time and sometimes there would be errors
reading the id register afterwards.
Add a msleep(20) after getting the reset line to ensure the sensor is
properly reset:
reset=1 // from probe() calling gpiod_get(GPIOD_OUT_HIGH)
msleep(20) // from probe()
reset=0 // from resume()

Set timing-related and BLC anchor registers via cci calls instead of
hardcoding them in the register table. This prepares the driver for
implementation of configurable analogue crop and binning. No
functional change intended.

Pixel array dimensions and default crop size do not belong to the
ov4689_mode structure, since they are mode independent. Make them
defines instead.

The OV4689 sensor has separate red and blue gain settings (up to 4x).
Implement appropriate controls in the driver. Default gain values

The OV4689 sensor supports horizontal and vertical flipping. Add
appropriate controls to the driver. Toggling both array flip and
digital flip bits allows to achieve flipping while maintaining output
Bayer order. Note that the default value of hflip control corresponds
to both bits set, as it was before this patch.

Make horizontal blanking configurable. To do so, set HTS register
according to the requested horizontal blanking in ov4689_set_ctrl
instead of the register table. Default HTS value is not changed by
this patch. Minimal HTS value is found experimentally and corresponds
to 90 fps framerate at minimum vertical blanking. Real HTS value is
the register value multiplied by 4.
