[PATCH 2/2] clocksource/drivers/renesas-ostm: Enable OSTM reprobe for RZ/V2N SoC

From: Prabhakar
Date: Thu May 01 2025 - 08:37:54 EST


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

Add CONFIG_ARCH_R9A09G056 to the probe condition in renesas-ostm.c so that
the OSTM platform driver can reprobe for the RZ/V2N (R9A09G056) SoC. Like
RZ/G2L and RZ/V2H(P), the RZ/V2N contains the Generic Timer Module (OSTM)
which requires its reset to be deasserted before any register access.
Enabling the platform_device probe path ensures the driver defers until
resets are available.
