[PATCH v2 13/13] dt: power: bq2425x-charger: Cover additional devices

[Andreas Dannenberg <dannenberg-l0cyMroinI0@public.gmane.org>]

Extend the bq2425x charger's device tree documentation to cover the
bq24250 and bq24257 devices as well as recent feature additions.

+Binding for TI bq2425x Li-Ion Charger
+
+Required properties:
+- compatible: Should contain one of the following:
+ * "ti,bq24250"
+ * "ti,bq24251"
+ * "ti,bq24257"
+- reg: integer, i2c address of the device.
+- stat-gpios: GPIO used for the devices STAT_IN pin. Alternatively the pin can
+    also be defined through the standard interrupt definition properties (see
+    optional properties section below). Only use one method.
+- ti,battery-regulation-voltage: integer, maximum charging voltage in uV.
+- ti,charge-current: integer, maximum charging current in uA.
+- ti,termination-current: integer, charge will be terminated when current in
+    constant-voltage phase drops below this value (in uA).
+
+Optional properties:
+- pg-gpios: GPIO used for connecting the bq2425x device PG (Power Good) pin.
+    This pin is not available on all devices however it should be used if
+    possible as this is the recommended way to obtain the charger's input PG
+    state. If this pin is not specified a software-based approach for PG
+    detection is used.
+- ti,current-limit: The maximum current to be drawn from the charger's input
+    (in uA). If this property is not specified a USB D+/D- signal based charger
+    type detection is used (if available) and the input limit current is set
+    accordingly. If the D+/D- based detection is not available on a given device
+    a default of 500,000 is used (=500mA).
+- ti,ovp-voltage: Configures the over voltage protection voltage (in uV). If
+    not specified a default of 6,5000,000 (=6.5V) is used.
+- ti,in-dpm-voltage: Configures the threshold input voltage for the dynamic
+    power path management (in uV). If not specified a default of 4,360,000
+    (=4.36V) is used.
+- ti,safety-timer-2x-enable: If this property is set to 1 the device's safety
+    timer is extended (slowed down) by a factor of two. Setting this property
+    to 0 or not providing it will leave the safety timer at its default
+    setting.
+- interrupt-parent: Should be the phandle for the interrupt controller. Use in
+    conjunction with "interrupts" and only in case "stat-gpios" is not used.
+- interrupts: Interrupt mapping for GPIO IRQ (configure for both edges). Use in
+    conjunction with "interrupt-parent" and only in case "stat-gpios" is not
+    used.
+
+Example:
+
+bq24257 {
+	compatible = "ti,bq24257";
+	reg = <0x6a>;
+	stat-gpios = <&gpio1 16 GPIO_ACTIVE_HIGH>;
+	pg-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>;
+
+	ti,battery-regulation-voltage = <4200000>;
+	ti,charge-current = <1000000>;
+	ti,termination-current = <50000>;
+};
+
+Example:
+
+bq24250 {
+	compatible = "ti,bq24250";
+	reg = <0x6a>;
+	interrupt-parent = <&gpio1>;
+	interrupts = <16 IRQ_TYPE_EDGE_BOTH>;
+
+	ti,battery-regulation-voltage = <4200000>;
+	ti,charge-current = <500000>;
+	ti,termination-current = <50000>;
+	ti,current-limit = <900000>;
+	ti,ovp-voltage = <9500000>;
+	ti,in-dpm-voltage = <4440000>;
+};
