[PATCH 2/2] mfd: max14577: Add device tree bindings document

[Tomasz Figa]

From: Krzysztof Kozlowski <k.kozlowski-Sze3O3UU22JBDgjK7y7TUQ@public.gmane.org>

Add document describing device tree bindings for MAX14577 MFD driver
(for both MAX14577 and MAX77836 chipsets).

+Maxim MAX14577/77836 Multi-Function Device
+
+MAX14577 is a Multi-Function Device with Micro-USB Interface Circuit, Li+
+Battery Charger and SFOUT LDO output for powering USB devices. It is
+interfaced to host controller using I2C.
+
+MAX77836 additionally contains PMIC (with two LDO regulators) and Fuel Gauge.
+
+
+Required properties:
+- compatible : Must be "maxim,max14577" or "maxim,max77836".
+- reg : I2C slave address for the max14577 chip (0x25 for max14577/max77836)
+- interrupts : IRQ line for the chip.
+- interrupt-parent :  The parent interrupt controller.
+
+
+Optional nodes:
+- max14577-muic/max77836-muic :
+	Node used only by extcon consumers.
+	Required properties:
+		- compatible : "maxim,max14577-muic" or "maxim,max77836-muic"
+
+- regulators :
+	Required properties:
+		- compatible : "maxim,max14577-regulator"
+			or "maxim,max77836-regulator"
+
+	May 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.
+
+	List of valid regulator names:
+	- for max14577: CHARGER, SAFEOUT.
+	- for max77836: CHARGER, SAFEOUT, LDO1, LDO2.
+
+	The SAFEOUT is a fixed voltage regulator so there is no need to specify
+	voltages for it.
+
+ - charger :
+	Required properties:
+		- compatible : "maxim,max14577-charger"
+			or "maxim,max77836-charger"
+		- maxim,fast-charge-timer : Timer in hours to trigger the
+			INT3/MBCCHGERR interrupt; Valid values:
+			- 5, 6 or 7 (hours),
+			- 0 to disable.
+		- maxim,fast-charge-uamp : Current in uA for Fast Charge;
+			Valid values:
+			- for max14577: 90000 - 950000;
+			- for max77836: 45000 - 475000;
+		- maxim,eoc-uamp : Current in uA for End-Of-Charge mode;
+			Valid values:
+			- for max14577: 50000 - 200000;
+			- for max77836: 5000 - 10000;
+		- maxim,ovp-uvolt : OverVoltage Protection Threshold in uV;
+			In an overvoltage condition, INT asserts and charging
+			stops. Valid values:
+			- 6000000, 6500000, 7000000, 7500000;
+		- maxim,constant-uvolt : Battery Constant Voltage in uV;
+			Valid values:
+			- 4000000 - 4280000;
+			- 4350000;
+
+
+Example:
+
+#include <dt-bindings/interrupt-controller/irq.h>

[Tomasz Figa]

Hi,

Oops, I have forgotten to add suppress-cc to git send-email and the 
series went outside the intended audience... Please disregard these patches.

Sorry for the noise.

Best regards,
Tomasz
