* 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>
