| Subject: [PATCH 1539/1795] arm64: dts: renesas: ulcb: Add PMIC DDR Backup |
| Power config |
| |
| 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". |
