Subject: [PATCH v2 2/3] arm64: dts: renesas: salvator-common: Configure PMIC for DDR Backup Power
Date: Wed, 14 Mar 2018 13:09:45 +0100	[thread overview]
Message-ID: <1521029386-29975-3-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1521029386-29975-1-git-send-email-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, hense specify
"rohm,rstbmode-level".

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v2:
  - Add rohm,rstbmode-level.
