+Subject: [PATCH] media: i2c: ov5647: Selection compliance fixes
+
+To comply with the intended usage of the V4L2 selection target when
+used to retrieve a sensor image properties, adjust the rectangles
+returned by the ov5647 driver.
+
+The top/left crop coordinates of the TGT_CROP rectangle were set to
+(0, 0) instead of (16, 16) which is the offset from the larger physical
+pixel array rectangle. This was also a mismatch with the default values
+crop rectangle value, so this is corrected. Found with v4l2-compliance.
+
+While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
+CROP_BOUNDS have the same size as the non-active pixels are not readable
+using the selection API. Found with v4l2-compliance.
