media: i2c: ov13b10: Fix h_blank calculation
Pixel per line (PPL) is calculated as pixel_rate / (VTS * FPS), which is not decided by MIPI CSI-2 link frequency. PPL can vary while link frequency keeps the same. If PPL is wrong, the h_blank = PPL - width is also wrong then FPS control is inaccurate. This patch fix h_blank by: 1. Move PPL from link_freq_config to ov13b10_mode 2. Add PPL value for different modes 3. Use PPL from mode to calculate h_blank Signed-off-by: Bingbu Cao <bingbu.cao@intel.com> Signed-off-by: Hao Yao <hao.yao@intel.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
