[PATCH 0/3] Add VSP and FCPVD support for RZ/T2H and RZ/N2H SoCs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Hi all,

This patch series adds support for the VSP and FCPVD blocks present on the
RZ/T2H and RZ/N2H SoCs. The VSP implementation on these SoCs is identical
to that found on the RZ/G2L SoC, while the FCPVD implementation
matches that found on the RZ/G2L family.

Note patches apply on top of [0].

Cheers,
Prabhakar

[PATCH 1/3] media: dt-bindings: media: renesas,fcp: Document RZ/T2H and RZ/N2H SoCs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Document the FCPVD blocks present on the RZ/T2H and RZ/N2H SoCs.

The FCPVD implementation on these SoCs is identical to that found on the
RZ/G2L family.

Update the schema to disallow the "resets" property for these SoCs,
reflecting the absence of a reset control for the FCPVD instance.

[PATCH 2/3] media: dt-bindings: media: renesas,vsp1: Document RZ/T2H and RZ/N2H SoCs

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Document the VSP2 blocks present on the RZ/T2H and RZ/N2H SoCs.

The VSP2 implementation on these SoCs is identical to that on the
RZ/G2L SoC.

Update the schema to disallow the "resets" property for these SoCs to
reflect the hardware integration.

[PATCH 3/3] media: renesas: vsp1: Make reset control optional to support platforms without a reset line

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Switch the VSP1 driver to use devm_reset_control_get_optional_shared()
when requesting its reset control. Some newer Renesas SoCs integrating
VSP1 such as RZ/T2H do not provide a reset line for the VSP IP block.
