[PATCH v2 1/4] phy: exynos4: Remove duplicated defines of PHY register defines

Krzysztof Kozlowski
2017-03-11T18:26:20Z

Phy drivers access PMU region through regmap provided by exynos-pmu
driver. However there is no need to duplicate defines for PMU
registers. Instead just use whatever is defined in exynos-regs-pmu.h.

Additionally MIPI PHY registers for Exynos5433 start from the same
address as Exynos4 and Exynos5250 so re-use existing defines.

This reduces number of defines and allows removal of one header file.
