   3 Required properties:
   4 - compatible : Should be from the list
   5   ti,twl6035-pmic
   6   ti,twl6036-pmic
   7   ti,twl6037-pmic
   8   ti,tps65913-pmic
   9   ti,tps65914-pmic
  10 and also the generic series names
  11   ti,palmas-pmic
  12 - interrupt-parent : The parent interrupt controller which is palmas.
  13 - interrupts : The interrupt number and the type which can be looked up here:
  14                arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
  15 - interrupts-name: The names of the individual interrupts.
  16
  17 Optional properties:
  18 - ti,ldo6-vibrator : ldo6 is in vibrator mode
  19
  20 Optional nodes:
  21 - regulators : Must contain a sub-node per regulator from the list below.
  22                Each sub-node should contain the constraints and initialization
  23                information for that regulator. See regulator.txt for a
  24                description of standard properties for these sub-nodes.
  25                Additional custom properties  are listed below.
  26
  27                For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
  28                smps45, smps457, smps7 depending on variant, smps6, smps[8-10],
  29                ldo[1-9], ldoln, ldousb.
  30
  31                Optional sub-node properties:
  32                ti,warm-reset - maintain voltage during warm reset(boolean)
  33                ti,roof-floor - control voltage selection by pin(boolean)
  34                ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
  35                2 - eco, 3 - forced pwm
  36                ti,smps-range - OTP has the wrong range set for the hardware so override
  37                0 - low range, 1 - high range.
