Subject: [PATCH 16/16] phy: exynos-mipi-video: Add support for Exynos 5420 and 5433 SoCs
Date: Mon, 2 May 2016 09:53:07 +0530 [thread overview]
Message-ID: <1462162987-13023-17-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1462162987-13023-1-git-send-email-kishon@ti.com>
From: Marek Szyprowski <m.szyprowski@samsung.com>
This patch adds support for MIPI DPHYs found in Exynos5420-compatible
(5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from
earlier by different offset of MIPI DPHY registers in PMU controllers
(Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to
separate system register controllers (Exynos 5433 case). In both case
also additional 5th PHY (MIPI CSIS 2) has been added.
