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";
62 interrupt-parent = <&palmas>;
63 interrupts = <14 IRQ_TYPE_NONE>;
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 {
84 regulator-name = "ldo1";
85 regulator-min-microvolt = <2800000>;
86 regulator-max-microvolt = <2800000>;
87 };
88 };
89 };
