[PATCH 082/102] arm64: dts: renesas: ulcb: Add PMIC DDR Backup Power config

From: Simon Horman <hidden>
Date: 2018-05-18 11:15:44
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 the R-Car Starter Kit Premier/Pro, 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 (SW8) is a momentary switch, hense specify
"rohm,rstbmode-pulse".
