   4 Subject: [PATCH] dtoverlays: Correct CSI2 settings for ov9281
   5
   6 OV9281 appears to drop the clock to LP mode between frames, but
   7 the overlay didn't define this at both ends of the CSI2 link.
   8 The overlay also had an incorrect link frequency defined, not that
   9 the driver ever checked for one.
  10
  11 Fix both issues.
