   3 The tps659038 for the AM57x class have OTP spins that
   4 have different part numbers but the same functionality. There
   5 is not a need to add the OTP spins to the palmas driver. The
   6 spin devices should use the tps659038 as it's compatible value.
   7 This is the list of those devices:
   8 tps659037
   9
  10 Required properties:
  11 - compatible : Should be from the list
  12   ti,twl6035-pmic
  13   ti,twl6036-pmic
  14   ti,twl6037-pmic
  15   ti,tps65913-pmic
  16   ti,tps65914-pmic
  17   ti,tps65917-pmic
  18   ti,tps659038-pmic
  19 and also the generic series names
  20   ti,palmas-pmic
  21 - interrupt-parent : The parent interrupt controller which is palmas.
  22 - interrupts : The interrupt number and the type which can be looked up here:
  23                arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
  24 - interrupts-name: The names of the individual interrupts.
  25
  26 Optional properties:
  27 - ti,ldo6-vibrator : ldo6 is in vibrator mode
  28
  29 Optional nodes:
  30 - regulators : Must contain a sub-node per regulator from the list below.
  31                Each sub-node should contain the constraints and initialization
  32                information for that regulator. See regulator.txt for a
  33                description of standard properties for these sub-nodes.
  34                Additional custom properties  are listed below.
  35
  36                For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
  37                smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
  38                smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
  39
  40                Optional sub-node properties:
  41                ti,warm-reset - maintain voltage during warm reset(boolean)
  42                ti,roof-floor - This takes as optional argument on platform supporting
  43                the rail from desired external control. If there is no argument then
  44                it will be assume that it is controlled by NSLEEP pin.
  45                The valid value for external pins are:
  46                         ENABLE1 then 1,
  47                         ENABLE2 then 2 or
  48                         NSLEEP then 3.
  49                ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
  50                2 - eco, 3 - forced pwm
  51                ti,smps-range - OTP has the wrong range set for the hardware so override
  52                0 - low range, 1 - high range.
  53
  54 - ti,system-power-controller: Telling whether or not this pmic is controlling
  55                               the system power.
  56
