Subject: [PATCH v5 1/5] media: dt-bindings: media: i2c: Deprecate usage of the clock-frequency property

OV5645 sensor supports input clock frequency ranging from 6MHz to 27MHz
but the driver strictly expects this to be 24MHz (with tolerance of 1%)
with this restrictions let the driver enforce the clock frequency
internally to 24MHz rather then being passed as dt-property.
