[PATCH] media: dt-bindings: Merge OV5695 into OV5693 binding

Rob Herring
2023-07-07T21:06:56Z

The OV5695 binding is almost the same as the OV5693 binding. The only
difference is 'clock-names' is defined for OV5695. However, the lack of
clock-names is an omission as the Linux OV5693 driver expects the same
'xvclk' clock name.

'link-frequencies' is required by OV5693, but not OV5695. Just drop it
from being required. Expressing it conditionally would be ugly. It
shouldn't really be required either as the driver only supports 1
frequency anyways.

The rockchip-isp1 binding example is missing required properties, so it
has to be updated as well.
