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	- 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	
57	Example:
58	
59	#include <dt-bindings/interrupt-controller/irq.h>
60	
61	pmic {
62		compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
63		interrupt-parent = <&palmas>;
64		interrupts = <14 IRQ_TYPE_NONE>;
65		interrupts-name = "short-irq";
66	
67		ti,ldo6-vibrator;
68	
69		ti,system-power-controller;
70	
71		regulators {
72			smps12_reg : smps12 {
73				regulator-name = "smps12";
74				regulator-min-microvolt = < 600000>;
75				regulator-max-microvolt = <1500000>;
76				regulator-always-on;
77				regulator-boot-on;
78				ti,warm-reset;
79				ti,roof-floor = <1>; /* ENABLE1 control */
80				ti,mode-sleep = <0>;
81				ti,smps-range = <1>;
82			};
83	
84			ldo1_reg: ldo1 {
85				regulator-name = "ldo1";
86				regulator-min-microvolt = <2800000>;
87				regulator-max-microvolt = <2800000>;
88			};
89		};
90	};
