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