J Keerthy8d561b62013-06-06 10:57:21 +0530[diff] [blame]1* palmas regulator IP block devicetree bindings
2
3Required properties:
4- compatible : Should be from the list
5 ti,twl6035-pmic
6 ti,twl6036-pmic
7 ti,twl6037-pmic
8 ti,tps65913-pmic
9 ti,tps65914-pmic
10and also the generic series names
11 ti,palmas-pmic
12- interrupt-parent : The parent interrupt controller which is palmas.
13- interrupts : The interrupt number and the type which can be looked up here:
14 arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
15- interrupts-name: The names of the individual interrupts.
16
17Optional properties:
18- ti,ldo6-vibrator : ldo6 is in vibrator mode
19
20Optional nodes:
21- regulators : Must contain a sub-node per regulator from the list below.
22 Each sub-node should contain the constraints and initialization
23 information for that regulator. See regulator.txt for a
24 description of standard properties for these sub-nodes.
25 Additional custom properties are listed below.

27 For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
Laxman Dewangan0416ea12013-08-13 13:23:10 +0530[diff] [blame]28 smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
Laxman Dewangan32b6d3f2013-08-21 16:18:16 +0530[diff] [blame]29 smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
J Keerthy8d561b62013-06-06 10:57:21 +0530[diff] [blame]30
31 Optional sub-node properties:
32 ti,warm-reset - maintain voltage during warm reset(boolean)
Laxman Dewangan32b6d3f2013-08-21 16:18:16 +0530[diff] [blame]33 ti,roof-floor - This takes as optional argument on platform supporting
34 the rail from desired external control. If there is no argument then
35 it will be assume that it is controlled by NSLEEP pin.
36 The valid value for external pins are:
37 ENABLE1 then 1,
38 ENABLE2 then 2 or
39 NSLEEP then 3.
Nishanth Menon393536f2013-07-16 11:41:09 -0500[diff] [blame]40 ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
J Keerthy8d561b62013-06-06 10:57:21 +0530[diff] [blame]41 2 - eco, 3 - forced pwm
J Keerthy8d561b62013-06-06 10:57:21 +0530[diff] [blame]42 ti,smps-range - OTP has the wrong range set for the hardware so override
43 0 - low range, 1 - high range.
44
Bill Huangb81eec02013-08-08 04:45:05 -0700[diff] [blame]45- ti,system-power-controller: Telling whether or not this pmic is controlling
46 the system power.
