* ROHM BD9571MWV Power Management Integrated Circuit (PMIC) bindings Required properties: - compatible : Should be "rohm,bd9571mwv". - reg : I2C slave address. - interrupts : The interrupt line the device is connected to. - interrupt-controller : Marks the device node as an interrupt controller. - #interrupt-cells : The number of cells to describe an IRQ, should be 2. The first cell is the IRQ number. The second cell is the flags, encoded as trigger masks from ../interrupt-controller/interrupts.txt. - gpio-controller : Marks the device node as a GPIO Controller. - #gpio-cells : Should be two. The first cell is the pin number and the second cell is used to specify flags. See ../gpio/gpio.txt for more information. - regulators: : List of child nodes that specify the regulator initialization data. Child nodes must be named after their hardware counterparts: - vd09 - vd18 - vd25 - vd33 - dvfs 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. Example: pmic: pmic@30 { compatible = "rohm,bd9571mwv"; reg = <0x30>; interrupt-parent = <&gpio2>; interrupts = <0 IRQ_TYPE_LEVEL_LOW>; interrupt-controller; #interrupt-cells = <2>; gpio-controller; #gpio-cells = <2>; rohm,ddr-backup-power = <0xf>; rohm,rstbmode-pulse; regulators { dvfs: dvfs { regulator-name = "dvfs"; regulator-min-microvolt = <750000>; regulator-max-microvolt = <1030000>; regulator-boot-on; regulator-always-on; }; }; };
