[PATCH AUTOSEL 6.12 03/36] Revert "watchdog: s3c2410_wdt: use exynos_get_pmu_regmap_by_phandle() for PMU regs"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Peter Griffin <peter.griffin@xxxxxxxxxx>

[ Upstream commit ccfb765944bb66813398958983cb8141e2624a6b ]

This reverts commit 746f0770f916e6c48e422d6a34e67eae16707f0e.

Now that we can register a SoC specific regmap with syscon using
of_syscon_register_regmap() api we can switch back to using
syscon_regmap_lookup_by_phandle() in the client drivers.
