power/supply: unify DT documentation

Currently the power supply device tree documentation is spread
in .../bindings/power_supply and .../bindings/power. This
unifies the files for chargers and battery fuel gauges in
.../bindings/power/supply and the ones for system reset/shutdown
in .../bindings/power/reset (same structure as used for the
drivers itself).

+Axxia Restart Driver
+
+This driver can do reset of the Axxia SoC. It uses the registers in the syscon
+block to initiate a chip reset.
+
+Required Properties:

+  -syscon: phandle to the syscon node.
+
+Example:
+
+	syscon: syscon@2010030000 {

+* QNAP Power Off
+
+QNAP NAS devices have a microcontroller controlling the main power
+supply. This microcontroller is connected to UART1 of the Kirkwood and
+Orion5x SoCs. Sending the character 'A', at 19200 baud, tells the
+microcontroller to turn the power off. This driver adds a handler to
+pm_power_off which is called to turn the power off.
+
+Synology NAS devices use a similar scheme, but a different baud rate,
+9600, and a different character, '1'.
+
+Required Properties:
+- compatible: Should be "qnap,power-off" or "synology,power-off"
+
+- reg: Address and length of the register set for UART1
+- clocks: tclk clock

+=== AB8500 Fuel Gauge Driver ===
+
+AB8500 is a mixed signal multimedia and power management
+device comprising: power and energy-management-module,
+wall-charger, usb-charger, audio codec, general purpose adc,
+tvout, clock management and sim card interface.
+
+Fuelgauge support is part of energy-management-modules, other
+components of this module are:
+main-charger, usb-combo-charger and battery-temperature-monitoring.
+
+The properties below describes the node for fuelgauge driver.
+
+Required Properties:
+- compatible = This shall be: "stericsson,ab8500-fg"
+- battery = Shall be battery specific information
+	Example:
+	ab8500_fg {
+		compatible = "stericsson,ab8500-fg";
+		battery	   = <&ab8500_battery>;
+	};
+
+dependent node:
+	ab8500_battery: ab8500_battery {
+	};
+	This node will provide information on 'thermistor interface' and
+	'battery technology type' used.
+
+Properties of this node are:
+thermistor-on-batctrl:
+	A boolean value indicating thermistor interface	to battery
+
+	Note:
+	'btemp' and 'batctrl' are the pins interfaced for battery temperature
+	measurement, 'btemp' signal is used when NTC(negative temperature
+	coefficient) resister is interfaced external to battery whereas
+	'batctrl' pin is used when NTC resister is internal to battery.
+
+	Example:
+	ab8500_battery: ab8500_battery {
+		thermistor-on-batctrl;
+	};
+	indicates: NTC resister is internal to battery, 'batctrl' is used
+		for thermal measurement.
+
+	The absence of property 'thermal-on-batctrl' indicates
+	NTC resister is external to battery and  'btemp' signal is used
+	for thermal measurement.
+
+battery-type:
+	This shall be the battery manufacturing technology type,
+	allowed types are:
+		"UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn"
+	Example:
+	ab8500_battery: ab8500_battery {

+TI BQ24735 Charge Controller
+~~~~~~~~~~
+
+Required properties :
+ - compatible : "ti,bq24735"
+
+Optional properties :
+ - interrupts : Specify the interrupt to be used to trigger when the AC
+   adapter is either plugged in or removed.
+ - ti,ac-detect-gpios : This GPIO is optionally used to read the AC adapter
+   presence. This is a Host GPIO that is configured as an input and
+   connected to the bq24735.
+ - ti,charge-current : Used to control and set the charging current. This value
+   must be between 128mA and 8.128A with a 64mA step resolution. The POR value
+   is 0x0000h. This number is in mA (e.g. 8192), see spec for more information
+   about the ChargeCurrent (0x14h) register.
+ - ti,charge-voltage : Used to control and set the charging voltage. This value
+   must be between 1.024V and 19.2V with a 16mV step resolution. The POR value
+   is 0x0000h. This number is in mV (e.g. 19200), see spec for more information
+   about the ChargeVoltage (0x15h) register.
+ - ti,input-current : Used to control and set the charger input current. This
+   value must be between 128mA and 8.064A with a 128mA step resolution. The
+   POR value is 0x1000h. This number is in mA (e.g. 8064), see the spec for
+   more information about the InputCurrent (0x3fh) register.
+ - ti,external-control : Indicates that the charger is configured externally
+   and that the host should not attempt to enable/disable charging or set the
+   charge voltage/current.
+
+Example:
+
+	bq24735@9 {
+		compatible = "ti,bq24735";
+		reg = <0x9>;
+		ti,ac-detect-gpios = <&gpio 72 0x1>;
