- * palmas regulator IP block devicetree bindings
- Required properties:
- - compatible : Should be from the list
- ti,twl6035-pmic
- ti,twl6036-pmic
- ti,twl6037-pmic
- ti,tps65913-pmic
- ti,tps65914-pmic
- and also the generic series names
- ti,palmas-pmic
- - interrupt-parent : The parent interrupt controller which is palmas.
- - interrupts : The interrupt number and the type which can be looked up here:
- arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
- - interrupts-name: The names of the individual interrupts.
- Optional properties:
- - ti,ldo6-vibrator : ldo6 is in vibrator mode
- Optional nodes:
- - regulators : Must contain a sub-node per regulator from the list below.
- Each sub-node should contain the constraints and initialization
- information for that regulator. See regulator.txt for a
- description of standard properties for these sub-nodes.
- Additional custom properties are listed below.
- For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
- smps45, smps457, smps7 depending on variant, smps6, smps[8-10],
- ldo[1-9], ldoln, ldousb.
- Optional sub-node properties:
- ti,warm-reset - maintain voltage during warm reset(boolean)
- ti,roof-floor - control voltage selection by pin(boolean)
- ti,sleep-mode - mode to adopt in pmic sleep 0 - off, 1 - auto,
- 2 - eco, 3 - forced pwm
- ti,tstep - slope control 0 - Jump, 1 10mV/us, 2 5mV/us, 3 2.5mV/us
- ti,smps-range - OTP has the wrong range set for the hardware so override
- 0 - low range, 1 - high range.
- Example:
- #include <dt-bindings/interrupt-controller/irq.h>
- pmic {
- compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
- interrupt-parent = <&palmas>;
- interrupts = <14 IRQ_TYPE_NONE>;
- interrupts-name = "short-irq";
- ti,ldo6-vibrator;
- regulators {
- smps12_reg : smps12 {
- regulator-name = "smps12";
- regulator-min-microvolt = < 600000>;
- regulator-max-microvolt = <1500000>;
- regulator-always-on;
- regulator-boot-on;
- ti,warm-reset;
- ti,roof-floor;
- ti,mode-sleep = <0>;
- ti,tstep = <0>;
- ti,smps-range = <1>;
- };
- ldo1_reg: ldo1 {
- regulator-name = "ldo1";
- regulator-min-microvolt = <2800000>;
- regulator-max-microvolt = <2800000>;
- };
- };
- };
