From 474706117c2baa68bf053f16cd35618d30bf4c06 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Wed, 13 Mar 2019 11:58:16 +0100 Subject: [PATCH] arm64: dts: renesas: ebisu: Add PMIC DDR0 Backup Power config On Ebisu the DDR0 power rail needs to be kept powered when backup mode is enabled. Reflect this in the "rohm,ddr-backup-power" property for the BD9571MWV PMIC node. The accessory power switch (SW23) is a toggle switch, hence specify "rohm,rstbmode-level". Based on advice from Geert Uytterhoeven.
