Subject: [PATCH v3 2/3] arm64: dts: renesas: salvator-common: Add PMIC DDR Backup Power config
Date: Thu, 3 May 2018 14:30:50 +0200 [thread overview]
Message-ID: <1525350651-12471-3-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1525350651-12471-1-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>

v3:
- Use a hex value for the bit mask,
v2:
- Add rohm,rstbmode-level.
