[PATCH 6.12.y-cip 0/8] Add RZ/V2N display support

[Ovidiu Panait]

Hi,

This series adds display support for the Renesas RZ/V2N SoC and EVK
board.

All patches were cherry-picked from mainline kernel.

Note: This series depends on:
https://lore.kernel.org/cip-dev/20260225121232.129678-1-ovidiu.panait.rb@renesas.com/

Best regards,
Ovidiu

[PATCH 6.12.y-cip 1/8] media: dt-bindings: media: renesas,fcp: Document RZ/V2N SoC

[Ovidiu Panait]

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

commit f42eddf44fbfc8c00b2ffb7779a8c11cf92d2b29 upstream.

The FCPVD block on the RZ/V2N SoC is identical to the one found on the
RZ/G2L SoC.

No driver changes are required, as `renesas,fcpv` will be used as a
fallback compatible string on the RZ/V2N SoC.

[PATCH 6.12.y-cip 2/8] media: dt-bindings: media: renesas,fcp: Allow three clocks for RZ/V2N SoC

[Ovidiu Panait]

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

commit ae8694393e13f563209fad681e5bc1b99d558646 upstream.

Update the FCP DT schema to permit three clock inputs for the RZ/V2N SoC.
The FCP block on this SoC requires three separate clocks, unlike other
variants which use only one.

[PATCH 6.12.y-cip 3/8] media: dt-bindings: media: renesas,vsp1: Document RZ/V2N SoC

[Ovidiu Panait]

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

commit 2632f288ab1180c42c9379893357b8b7744fbf92 upstream.

The VSPD block on the RZ/V2N SoC is identical to the one found on the

No driver changes are required, as `renesas,r9a07g044-vsp2` will be used
as a fallback compatible string on the RZ/V2N SoC.

[PATCH 6.12.y-cip 4/8] dt-bindings: display: renesas,rzg2l-du: Add support for RZ/V2N SoC

[Ovidiu Panait]

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

commit e96a7dc6de5f6c2cac8cc919584c95ae52cf1f9a upstream.

Document support for the DU IP found on the Renesas RZ/V2N (R9A09G056) SoC.
The DU IP is functionally identical to that on the RZ/V2H(P) SoC, so no
driver changes are needed. The existing `renesas,r9a09g057-du` compatible
will be used as a fallback for the RZ/V2N SoC.

[PATCH 6.12.y-cip 5/8] clk: renesas: r9a09g056: Add clocks and resets for DSI and LCDC modules

[Ovidiu Panait]

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

commit d64522b54b26229ee074137135dbbcba72a4600b upstream.

Add clock and reset definitions required to support the DSI and LCDC
hardware blocks on the RZ/V2N SoC. This includes new core clocks, clock
dividers, module clocks, and reset entries, as well as PLL and divider
configurations specific to these peripherals.

Similar to 6.12, this looks okay to me.

Reviewed-by: Pavel Machek <pavel@nabladev.com>

I can apply the series if it passes testing and there are no other
comments.

Looks like this series is not present in the 6.12 branch, could you
please double check?

You seem to be right, sorry about that. It looks like I forgot to push

retest and likely push the result "soon".
