Subject: [PATCH v2 1/2] dt-bindings: timer: renesas,ostm: Document RZ/V2N (R9A09G056) support

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

Document support for the Renesas OS Timer (OSTM) found on the Renesas
RZ/V2N (R9A09G056) SoC. The OSTM IP on RZ/V2N is identical to that on
other RZ families, so no driver changes are required as `renesas,ostm`
will be used as fallback compatible.

Also update the bindings to require the "resets" property for RZ/V2N
by inverting the logic: all SoCs except RZ/A1 and RZ/A2 now require
the "resets" property.

Hi Geert,
I've restored the Reviewed-by tag from v1 with your suggestions applied.
I hope you're okay with this.
Cheers, Prabhakar
 
v1->v2:
- Inveted the logic in the dt-bindings to require the "resets" property
- Updated commit message
- Added a Reviewed-by tag from Geert.
