Subject: [PATCH 9/9] ARM: dts: Configure regulators for suspend on exynos Peach boards
Date: Wed, 15 Oct 2014 18:20:39 +0200 [thread overview]
Message-ID: <1413390039-19364-10-git-send-email-javier.martinez@collabora.co.uk> (raw)
In-Reply-To: <1413390039-19364-1-git-send-email-javier.martinez@collabora.co.uk>
The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
the max77802 driver supports changing the regulator operating
mode during runtime and when the system enters into sleep mode.
To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel.
