Subject: [PATCH v2 1/4] phy: exynos4: Remove duplicated defines of PHY register defines
Date: Sat, 11 Mar 2017 20:25:31 +0200 [thread overview]
Message-ID: <20170311182534.13345-2-krzk@kernel.org> (raw)
In-Reply-To: <20170311182534.13345-1-krzk@kernel.org>
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.
