media: imx258: Rectify mismatch of VTS value
[ Upstream commit 51f93add3669f1b1f540de1cf397815afbd4c756 ]
The frame_length_lines (0x0340) registers are hard-coded as follows:
- 4208x3118
frame_length_lines = 0x0c50
- 2104x1560
frame_length_lines = 0x0638
- 1048x780
frame_length_lines = 0x034c
The driver exposes the V4L2_CID_VBLANK control in read-only mode and
sets its value to vts_def - height, where vts_def is a mode-dependent
value coming from the supported_modes array. It is set using one of
the following macros defined in the driver:
#define IMX258_VTS_30FPS 0x0c98
#define IMX258_VTS_30FPS_2K 0x0638
#define IMX258_VTS_30FPS_VGA 0x034c
There's a clear mismatch in the value for the full resolution mode i.e.
IMX258_VTS_30FPS. Fix it by rectifying the macro with the value set for
the frame_length_lines register as stated above.
