[PATCH 081/102] arm64: dts: renesas: salvator-common: Add PMIC DDR Backup Power config

From: Simon Horman <hidden>
Date: 2018-05-18 11:15:43
Also in: linux-renesas-soc
Subsystem: arm/risc-v/renesas architecture, the rest · Maintainers: Geert Uytterhoeven, Magnus Damm, Linus Torvalds

From: Geert Uytterhoeven <geert+renesas@glider.be>

On Salvator-X(S), all of the DDR0, DDR1, DDR0C, and DDR1C power rails
need 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".
