Subject: [PATCH 2/5] ARM: dts: am43xx-epos-evm: Keep DCDC3 regulator on in suspend to memory
Date: Fri, 29 Mar 2019 12:53:33 -0500	[thread overview]
Message-ID: <20190329175336.19824-2-afd@ti.com> (raw)
In-Reply-To: <20190329175336.19824-1-afd@ti.com>

From: Mike Erdahl <m-erdahl@ti.com>

When going to suspend to ram mode (or rtc-only mode), the DDR regulator
must be told to stay on, else this rail will go down when the PMIC_EN
signal is deasserted.
