   4 Subject: [PATCH] dtoverlays: Convert ov5647 to use the regulator
   5  framework
   6
   7 Fixing up shutdown GPIOs via overrides is ugly, and doesn't work
   8 on eg CM4 where both cameras share the same shutdown GPIO.
   9
  10 The driver is now updated to use the regulator framework, so switch
  11 to using that instead.
