| Subject | [PATCH v5 3/3] mfd: wm831x: Add device tree binding document |
| Message-ID | <tlX9g-4MK-7@gated-at.bofh.it> |
Add a device tree binding document for the wm831x series of PMICs.
Currently only support for the registering the device and the GPIOs are
actually implemented in the driver.
Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com>

Changes since v4:
- Removed one extra level of ../ for relative links that was incorrect
Thanks,
Charles

+Cirrus Logic/Wolfson Microelectronics wm831x PMICs
+
+System PMICs with a wide range of additional features.
+
+Required properties:
+
+ - compatible : One of the following chip-specific strings:
+ "wlf,wm8310"
+ "wlf,wm8311"
+ "wlf,wm8312"
+ "wlf,wm8320"
+ "wlf,wm8321"
+ "wlf,wm8325"
+ "wlf,wm8326"
+
+ - reg : I2C slave address when connected using I2C, chip select number
+ when using SPI.
+
+ - gpio-controller : Indicates this device is a GPIO controller.
+ - #gpio-cells : Must be 2. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+
+ - interrupts : The interrupt line the IRQ signal for the device is
+ connected to.
+ - interrupt-parent : The parent interrupt controller.
+
+ - interrupt-controller : wm831x devices contain interrupt controllers and
+ may provide interrupt services to other devices.
+ - #interrupt-cells: Must be 2. The first cell is the IRQ number, and the
+ second cell is the flags, encoded as the trigger masks from
+ ../interrupt-controller/interrupts.txt
+
+Optional sub-nodes:
+ - regulators : Contains sub-nodes for each of the regulators supplied by
+ the device. The regulators are bound using their names listed below:
+
+ dcdc1 : DCDC1
+ dcdc2 : DCDC2
+ dcdc3 : DCDC3
+ dcdc4 : DCDC3
+ isink1 : ISINK1
+ isink2 : ISINK2
+ ldo1 : LDO1
+ ldo2 : LDO2
+ ldo3 : LDO3
+ ldo4 : LDO4
+ ldo5 : LDO5
+ ldo7 : LDO7
+ ldo11 : LDO11
+
+ The bindings details of each regulator can be found in:
+ ../regulator/regulator.txt
+
+Example:
+
+wm8310: pmic@36 {
+ compatible = "wlf,wm8310";
+ reg = <0x36>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ interrupts = <347>;
+ interrupt-parent = <&gic>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;
+
+ regulators {
+ dcdc1: dcdc1 {
+ regulator-name = "DCDC1";
+ regulator-min-microvolt = <600000>;
+ regulator-max-microvolt = <600000>;
+ };
+ ldo1: ldo1 {
+ regulator-name = "LDO1";
+ regulator-min-microvolt = <1700000>;
+ regulator-max-microvolt = <1700000>;
+ };
