[PATCH V3 0/2] Add device tree support for DA9063

[PATCH V3 0/2] Add device tree support for DA9063

[Steve Twiss]

From: Steve Twiss <stwiss.opensource@diasemi.com>

This patch set adds device tree support for the Dialog
Semiconductor DA9063 PMIC. Support is provided for the
Regulators; Real-Time Clock and Watchdog.

[PATCH V2 1/2]: kernel driver device tree support
[PATCH V2 2/2]: device tree bindings document

Change History:

[PATCH V3]: remove device tree information that explicitly
            identifies different silicon variants
[PATCH V2]: split into two patches and move the compatibility
            strings to the end of the structures.
[PATCH V1]: initial submission

Thank you,
Steve Twiss, Dialog Semiconductor Ltd.

+da9063-watchdog         :               : Watchdog
+
+======
+
+Required properties:
+
+- compatible : Should be "dlg,da9063"
+- reg : Specifies the I2C slave address (this defaults to 0x58 but it can be
+  modified to match the chip's OTP settings).
+- interrupt-parent : Specifies the reference to the interrupt controller for
+  the DA9063.
+- interrupts : IRQ line information.
+- interrupt-controller
+
+Sub-nodes:
+
+- regulators : This node defines the settings for the LDOs and BUCKs. The
+  DA9063 regulators are bound using their names listed below:
+
+    bcore1    : BUCK CORE1
+    bcore2    : BUCK CORE2
+    bpro      : BUCK PRO
+    bmem      : BUCK MEM
+    bio       : BUCK IO
+    bperi     : BUCK PERI
+    ldo1      : LDO_1
+    ldo2      : LDO_2
+    ldo3      : LDO_3
+    ldo4      : LDO_4
+    ldo5      : LDO_5
+    ldo6      : LDO_6
+    ldo7      : LDO_7

+    ldo9      : LDO_9
+    ldo10     : LDO_10

+
+  The component follows the standard regulator framework and the bindings
+  details of individual regulator device can be found in:
+  Documentation/devicetree/bindings/regulator/regulator.txt
+
+- rtc : This node defines settings for the Real-Time Clock associated with
+  the DA9063. There are currently no entries in this binding, however
+  compatible = "dlg,da9063-rtc" should be added if a node is created.
+
+- watchdog : This node defines settings for the Watchdog timer associated
+  with the DA9063. There are currently no entries in this binding, however
+  compatible = "dlg,da9063-watchdog" should be added if a node is created.
+
+

+
+	pmic0: da9063@58 {
+		compatible = "dlg,da9063"
+		reg = <0x58>;
+		interrupt-parent = <&gpio6>;

I already Acked this?  Any reason that wasn't carried forward to this
submission?  Has anything changed?

Yes, I had to alter this bindings document because of the compatible change ...

This is why in-patch changelogs are helpful. ;)

Applied now, thanks.
