Subject: [PATCH 03/12] ARM: dts: Exynos5420: add CPU OPP and regulator supply property
Date: Wed,  2 Dec 2015 22:19:18 +0100
Message-ID: <1449091167-20758-4-git-send-email-ben@smart-cactus.org> (raw)
In-Reply-To: <1449091167-20758-1-git-send-email-ben@smart-cactus.org>

From: Thomas Abraham <thomas.ab@samsung.com>

For Exynos5420 platforms, add CPU operating points and CPU
regulator supply properties for migrating from Exynos specific
cpufreq driver to using generic cpufreq driver.

Changes by Bartlomiej:
- split Exynos5420 support from the original patch

Changes by Ben Gamari:
- Port to operating-points-v2
