3The tps659038 for the AM57x class have OTP spins that
4have different part numbers but the same functionality. There
5is not a need to add the OTP spins to the palmas driver. The
6spin devices should use the tps659038 as it's compatible value.
7This is the list of those devices:
8tps659037
9
10Required 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
19and 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
25Optional properties:
26- ti,ldo6-vibrator : ldo6 is in vibrator mode
27
28Optional 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.
