[PATCH v2 0/3] dt-bindings: RCar FCP and FDP1 bindings

[Kieran Bingham]

This updated series, has collected the Acked and Reviewed tags for the
FCPF binding addition, and adds documention of the optional power-domain
property for the FCP.

Finally the FDP1 bindings have been updated following review from Laurent.

Specifically, this removes the version specific compatibles as we have a
HW version register available to us in the hardware so we can detect at
run-time what device version we are running on.

[PATCH v2 1/3] dt-bindings: Update Renesas R-Car FCP DT binding

[Kieran Bingham]

The FCP driver can also support the FCPF variant for FDP1 compatible
processing.

[PATCH v2 2/3] dt-bindings: Document Renesas R-Car FCP power-domains usage

[Kieran Bingham]

The power domain must be specified to bring the device out of module
standby. Document this in the bindings provided, so that new additions
are not missed.

[PATCH v2 3/3] dt-bindings: Add Renesas R-Car FDP1 bindings

[Kieran Bingham]

The FDP1 is a de-interlacing module which converts interlaced video to
progressive video. It is also capable of performing pixel format conversion
between YCbCr/YUV formats and RGB formats.

Changes since v1:
 - title fixed
 - Interrupts property documented
 - version specific compatibles removed as we have a hw version register
 - label removed from device node example
