Hi Sakari,
Thank you for the patch.

Add smiapp driver specific control sub-class for test pattern controls. More
controls are expected since a fair amount of the standard functionality is
still unsupported. There are sensor model specific functionality as well
and expectedly thus also sensor specific controls. So reserve 128 controls
for this driver.
This patch also adds test pattern controls for the four colour components.

This patch comes before the previous patch I sent to the thread. I missed
this when sending it.

Wouldn't it make sense to create a standard test pattern color control instead
? Several sensors can control the test pattern color in a way or another. Some
of them might need more than one color though, so I'm not sure how much
standardization would be possible.
Now that you mention it, I'd guess many raw bayer sensors can set
colours for the test pattern (or image). The menu control has no
standardised values so I didn't think of standardising controls that
depend on it.
I'll update the patches (and add a new one for the standard controls).
