Subject: [PATCH v4 4/5] phy: samsung: phy-exynos-pcie: rework driver to support Exynos5433 PCIe PHY
Date: Fri, 13 Nov 2020 18:01:38 +0100 [thread overview]
Message-ID: <20201113170139.29956-5-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20201113170139.29956-1-m.szyprowski@samsung.com>
From: Jaehoon Chung <jh80.chung@samsung.com>
Exynos5440 SoC support has been dropped since commit 8c83315da1cf ("ARM:
dts: exynos: Remove Exynos5440"). Rework this driver to support PCIe PHY
variant found in the Exynos5433 SoCs.
Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com>
[mszyprow: reworked the driver to support only Exynos5433 variant, rebased
onto current kernel code, rewrote commit message]
