dt-bindings:iio:adc:ti,palmas-gpadc: txt to yaml format conversion. 

Simple conversion of the binding doc for this subnode of the palmas
PMIC.
Given age of driver and lack interaction with original authors,
I've guessed at Tony for a maintainer on this one.  Tony, if you
are happy with that great, otherwise I can default back to myself.

* Palmas general purpose ADC IP block devicetree bindings
Channels list:
0 battery type
1 battery temp NTC (optional current source)
2 GP
3 temp (with ext. diode, optional current source)
4 GP
5 GP
6 VBAT_SENSE
7 VCC_SENSE
8 Backup Battery voltage
9 external charger (VCHG)
10 VBUS
11 DC-DC current probe (how does this work?)
12 internal die temp
13 internal die temp
14 USB ID pin voltage
15 test network
Required properties:
- compatible : Must be "ti,palmas-gpadc".
- #io-channel-cells: Should be set to <1>.
Optional sub-nodes:
ti,channel0-current-microamp: Channel 0 current in uA.
Values are rounded to derive 0uA, 5uA, 15uA, 20uA.
ti,channel3-current-microamp: Channel 3 current in uA.
Values are rounded to derive 0uA, 10uA, 400uA, 800uA.
ti,enable-extended-delay: Enable extended delay.
Example:
pmic {
compatible = "ti,twl6035-pmic", "ti,palmas-pmic";
...
gpadc {
compatible = "ti,palmas-gpadc";
interrupts = <18 0
16 0
17 0>;
#io-channel-cells = <1>;
ti,channel0-current-microamp = <5>;
ti,channel3-current-microamp = <10>;
};
};
...
};
