[PATCH 18/26] arm64: dts: renesas: ebisu: Add PMIC DDR0 Backup Power config

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
