[PATCH v3 2/2] watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs

From: Peter Griffin
Date: Fri Feb 02 2024 - 09:58:33 EST


Obtain the PMU regmap using the new API added to exynos-pmu driver rather
than syscon_regmap_lookup_by_phandle(). As this driver no longer depends
on mfd syscon remove that header and Kconfig dependency.
