   4 Subject: [PATCH 1057/1085] dts: overlay: ov5647: Specify clock-noncontinuous
   5  on CSI endpoint
   6
   7 The OV5647 declares that it wants a non-continuous clock in its endpoint
   8 configuration. However, it does not expose this information via
   9 get_mbus_config. Even if it would implement get_mbus_config the
  10 bcm2835-unicam driver would not evaluate the flags field of it.
  11
  12 By also specifying clock-noncontinuous on the CSI endpoint itself, the
  13 CSI driver properly picks up the requests and enables the non-continuous
  14 clock mode.
