Subject: [PATCH] media: i2c: ov5647: Add support for g_selection to
|
|
reflect cropping/binning
|
|
|
|
In order to apply lens shading correctly the client needs to know how
|
|
each mode crops or scales the image compared to the full sensor array.
|
|
Implement this (based on the imx219 equivalent).
