charset="utf-8" From: Lad Prabhakar 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.
