Each child node is defined using the standard
binding for regulators.
+Optional properties:
+ - rohm,ddr-backup-power : Value to use for DDR-Backup Power (default 0).
+ This is a bitmask that specifies which DDR power
+ rails need to be kept powered when backup mode is
+ entered, for system suspend:
+ - bit 0: DDR0
+ - bit 1: DDR1
+ - bit 2: DDR0C
+ - bit 3: DDR1C
+ These bits match the KEEPON_DDR* bits in the
+ documentation for the "BKUP Mode Cnt" register.
+ - rohm,rstbmode-level: The RSTB signal is configured for level mode, to
+ accommodate a toggle power switch (the RSTBMODE pin is
+ strapped low).
+ - rohm,rstbmode-pulse: The RSTB signal is configured for pulse mode, to
+ accommodate a momentary power switch (the RSTBMODE pin
+ is strapped high).
+ The two properties above are mutually exclusive.
