Rob Herring 791d3ef2e1 dt-bindings: remove 'interrupt-parent' from bindings
'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

* palmas regulator IP block devicetree bindings
The tps659038 for the AM57x class have OTP spins that
have different part numbers but the same functionality. There
is not a need to add the OTP spins to the palmas driver. The
spin devices should use the tps659038 as it's compatible value.
This is the list of those devices:
tps659037
Required properties:
- compatible : Should be from the list
ti,twl6035-pmic
ti,twl6036-pmic
ti,twl6037-pmic
ti,tps65913-pmic
ti,tps65914-pmic
ti,tps65917-pmic
ti,tps659038-pmic
and also the generic series names
ti,palmas-pmic
- interrupts : The interrupt number and the type which can be looked up here:
arch/arm/boot/dts/include/dt-bindings/interrupt-controller/irq.h
- interrupts-name: The names of the individual interrupts.
Optional properties:
- ti,ldo6-vibrator : ldo6 is in vibrator mode
Optional nodes:
- regulators : Must contain a sub-node per regulator from the list below.
Each sub-node should contain the constraints and initialization
information for that regulator. See regulator.txt for a
description of standard properties for these sub-nodes.
Additional custom properties are listed below.
For ti,palmas-pmic - smps12, smps123, smps3 depending on OTP,
smps45, smps457, smps7 depending on variant, smps6, smps[8-9],
smps10_out2, smps10_out1, ldo[1-9], ldoln, ldousb.
Optional sub-node properties:
ti,warm-reset - maintain voltage during warm reset(boolean)
ti,roof-floor - This takes as optional argument on platform supporting
the rail from desired external control. If there is no argument then
it will be assume that it is controlled by NSLEEP pin.
The valid value for external pins are:
ENABLE1 then 1,
ENABLE2 then 2 or
NSLEEP then 3.
ti,mode-sleep - mode to adopt in pmic sleep 0 - off, 1 - auto,
2 - eco, 3 - forced pwm
ti,smps-range - OTP has the wrong range set for the hardware so override
0 - low range, 1 - high range.
- ti,system-power-controller: Telling whether or not this pmic is controlling
the system power.
Example:
#include <dt-bindings/interrupt-controller/irq.h>
pmic {
compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
interrupt-parent = <&palmas>;
interrupts = <14 IRQ_TYPE_NONE>;
interrupts-name = "short-irq";
ti,ldo6-vibrator;
ti,system-power-controller;
regulators {
smps12_reg : smps12 {
regulator-name = "smps12";
regulator-min-microvolt = < 600000>;
regulator-max-microvolt = <1500000>;
regulator-always-on;
regulator-boot-on;
ti,warm-reset;
ti,roof-floor = <1>; /* ENABLE1 control */
ti,mode-sleep = <0>;
ti,smps-range = <1>;
};
ldo1_reg: ldo1 {
regulator-name = "ldo1";
regulator-min-microvolt = <2800000>;
regulator-max-microvolt = <2800000>;
};
};
};
