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