Subject: [PATCH 09/32] phy: exynos4: Remove duplicated defines of PHY register defines
Date: Mon, 10 Apr 2017 18:48:00 +0530	[thread overview]
Message-ID: <20170410131823.26485-10-kishon@ti.com> (raw)
In-Reply-To: <20170410131823.26485-1-kishon@ti.com>

From: Krzysztof Kozlowski <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.
