The
sensor data sheet shows that binning is available, I guess they just haven't put it into the drivers yet. And if I am reading it right it is saying RGB binning is available on the colour sensor?

Digital Binning
By default, the resolution of the output image is the full width and height of the FOV as
defined above. The output resolution can be reduced by digital binning. For RGB and
monochrome mode, this is set by the register R0x3032. For Context A, use bits [1:0], for
Context B, use bits [5:4]. Available settings are:
00 = No binning
01 = Horizontal binning
10 = Horizontal and vertical binning
Binning gives the advantage of reducing noise at the cost of reduced resolution. When
both [horizontal and vertical binning are used, a 2x improvement in SNR is achieved,
therefore improving low light performance
Bayer Space Resampling
All of the pixels in the FOV contribute to the output image in digital binning mode. This
can result in a more pleasing output image with reduced subsampling artifacts. It also
improves low-light performance. For RGB and monochrome mode, the digital binning
factor is set by the register DIGITAL_BINNING (R0x3032). For Context A, use bits [1:0],
for Context B, use bits [5:4]. Available settings are: 00 = No binning; 01 = Horizontal
binning; 10 = Horizontal and vertical binning. For RGB mode, resampling can be
enabled by setting of register 0x306E[4] = 1.
