Subject: [PATCH] ARM: dts: exynos: Add proper regulator states for suspend-to-mem for odroid-u3
Date: Tue,  4 Dec 2018 19:40:25 +0000	[thread overview]
Message-ID: <20181204194025.2719-1-linux.amoon@gmail.com> (raw)

Add suspend-to-mem node to regulator core to be enabled or disabled
during system suspend and also support changing the regulator operating
mode during runtime and when the system enter sleep mode.
