    1 * palmas regulator IP block devicetree bindings
    2 
    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 - interrupts : The interrupt number and the type which can be looked up here:
   22                arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
   23 - interrupts-name: The names of the individual interrupts.
   24 
   25 Optional properties:
   26 - ti,ldo6-vibrator : ldo6 is in vibrator mode
   27 
   28 Optional nodes:
   29 - regulators : Must contain a sub-node per regulator from the list below.
   30                Each sub-node should contain the constraints and initialization
   31                information for that regulator. See regulator.txt for a
   32                description of standard properties for these sub-nodes.
   33                Additional custom properties  are listed below.
   34 
   35                For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
   36                smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
   37                smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
   38 
   39                Optional sub-node properties:
   40                ti,warm-reset - maintain voltage during warm reset(boolean)
   41                ti,roof-floor - This takes as optional argument on platform supporting
   42                the rail from desired external control. If there is no argument then
   43                it will be assume that it is controlled by NSLEEP pin.
   44                The valid value for external pins are:
   45                         ENABLE1 then 1,
   46                         ENABLE2 then 2 or
   47                         NSLEEP then 3.
   48                ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
   49                2 - eco, 3 - forced pwm
   50                ti,smps-range - OTP has the wrong range set for the hardware so override
   51                0 - low range, 1 - high range.
   52 
   53 - ti,system-power-controller: Telling whether or not this pmic is controlling
   54                               the system power.
   55 
   56 Example:
   57 
   58 #include <dt-bindings/interrupt-controller/irq.h>
   59 
   60 pmic {
   61         compatible = "ti,twl6035-pmic", "ti,palmas-pmic";

   64         interrupts-name = "short-irq";
   65 
   66         ti,ldo6-vibrator;
   67 
   68         ti,system-power-controller;
   69 
   70         regulators {
   71                 smps12_reg : smps12 {
   72                         regulator-name = "smps12";
   73                         regulator-min-microvolt = < 600000>;
   74                         regulator-max-microvolt = <1500000>;
   75                         regulator-always-on;
   76                         regulator-boot-on;
   77                         ti,warm-reset;
   78                         ti,roof-floor = <1>; /* ENABLE1 control */
   79                         ti,mode-sleep = <0>;
   80                         ti,smps-range = <1>;
   81                 };
   82 
   83                 ldo1_reg: ldo1 {

   86                         regulator-max-microvolt = <2800000>;
   87                 };
