标题: 高速视频采集报警告
最近在rv1126平台移植了一款高速120fps摄像头ov9281，用的双MIPI方案，在高帧率采集视频数据的时候会报以下警告：
  1. [   42.524069] rkisp0: tx stream:4 lose frame:2811, isp state:0x201 frame:2807
  2. [   42.538468] rkcif_mipi_lvds: frame drop to dummy buf, mipi/lvds stream[0]
  3. [   42.541029] rkisp0: tx stream:4 lose frame:2813, isp state:0x204 frame:2810
  4. [   42.555058] rkcif_mipi_lvds: frame drop to dummy buf, mipi/lvds stream[0]

如果在60fps以下都不会报以上警告，帧率越高以上警告越频繁。有大哥了解这个警告吗

没有 debug 过这个 sensor，这个看着像是性能问题

这个警报是因为你驱动没有配置好相应 sensor 的 fps。导致应用层不能及时获取到摄像头的数据。
