[PATCH 09/17] phy: samsung-ufs: use exynos_get_pmu_regmap_by_phandle() to obtain PMU regmap

From: Peter Griffin
Date: Thu Apr 04 2024 - 08:31:50 EST


This allows us to obtain a PMU regmap that is created by the exynos-pmu
driver. Platforms such as gs101 require exynos-pmu created regmap to
issue SMC calls for PMU register accesses. Existing platforms still get
a MMIO regmap as before.
