[PATCH 0/8] d-bindings: media: Conversion of Renesas bindings to YAML

[Laurent Pinchart]

Hello,

This patch series converts the DT bindings for the Renesas R-Car FCP,
FDP1 and VSP1 to YAML. It also updates the bindings based on the
properties that have been added to the DT sources over time but never
documented.

Laurent Pinchart (8):
  dt-bindings: media: renesas,fcp: Convert binding to YAML
  dt-bindings: media: renesas,fcp: Make power-domains mandatory
  dt-bindings: media: renesas,fcp: Add resets and iommus properties
  dt-bindings: media: renesas,fdp1: Convert binding to YAML
  dt-bindings: media: renesas,fdp1: Make power-domains mandatory
  dt-bindings: media: renesas,fdp1: Add resets property
  dt-bindings: media: renesas,vsp1: Convert binding to YAML
  dt-bindings: media: renesas,vsp1: Add power-domains and resets

[PATCH 3/8] dt-bindings: media: renesas,fcp: Add resets and iommus properties

[Laurent Pinchart]

The resets and iommus properties are used in DT sources in the kernel
tree. Document them, and make resets mandatory. The iommus property is
optional as not all platforms wire the FCP to a functional IOMMU.

I would drop the "for" part, and just write e.g. "# FCP for VSP".

Bummer, we don't have family-specific compatible values to enforce this
in yaml ;-)

I would do it the terse way, and just write e.g. "# R-Car Gen2 and RZ/G1".
