Subject: [PATCH V3 3/9] Documentation: devicetree: thermal: da9062/61 TJUNC
 temperature binding

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

Device tree binding information for DA9062 and DA9061 thermal junction
temperature monitor.

Binding descriptions for the DA9061 and DA9062 thermal TJUNC supervisor
device driver, using a single THERMAL_TRIP_HOT trip-wire and allowing for
a configurable polling period for over-temperature polling.

This patch also adds two examples, one for DA9062 and one for DA9061. The 
DA9061 example uses a fall-back compatible string for the DA9062.

This patch applies against linux-next and v4.8

v2 -> v3
 - Patch renamed from [PATCH V2 03/10] to [PATCH V3 3/9]
 - Changes suggested from other component reviews by Rob Herring:
 - Each compatible line should be a valid combination of compatible
   strings: alter DA9061 line to include the fall back compatible string
   and update the commit message accordingly
 - Add e-mail information about associated patches from this set without
   describing them as being explicitly dependent on this binding

v1 -> v2
 - Patch renamed from [PATCH V1 08/10] to [PATCH V2 03/10] -- these
   changes were made to fix checkpatch warnings caused by the patch
   set dependency order
 - A second example for DA9061 is provided to highlight the use of a
   fall-back compatible option for the DA9062

Hi,

The older [PATCH V1 08/10] was acked-by: Rob Herring, however this has
not been added because changes have been made to add a new binding
example. This describes the use of DA9061.
This addition was made after alterations to the device driver meant that a
fall-back compatible string could reuse the DA9062 device driver.

The device driver from this patch set (associated with this binding) is:
  [PATCH V3 8/9] thermal: da9061: TJUNC temperature driver

Steve Twiss, Dialog Semiconductor Ltd.

+* Dialog DA9062/61 TJUNC Thermal Module
+
+This module is part of the DA9061/DA9062. For more details about entire
+DA9062 and DA9061 chips see Documentation/devicetree/bindings/mfd/da9062.txt
+
+Junction temperature thermal module uses an interrupt signal to identify
+high THERMAL_TRIP_HOT temperatures for the PMIC device.
+
+Required properties:
+
+- compatible: should be one of the following valid compatible string lines:
+        "dlg,da9061-thermal", "dlg,da9062-thermal"
+        "dlg,da9062-thermal"
+
+Optional properties:
+
+- dlg,tjunc-temp-polling-period-ms : Specify the polling period, measured
+    in milliseconds, between thermal zone device update checks.
+
+Example: DA9062
+
+	pmic0: da9062@58 {
+		thermal {
+			compatible = "dlg,da9062-thermal";
+			dlg,tjunc-temp-polling-period-ms = <3000>;
+		};
+	};
+
+Example: DA9061 using a fall-back compatible for the DA9062 onkey driver
+
+	pmic0: da9061@58 {
+		thermal {
+			compatible = "dlg,da9061-thermal", "dlg,da9062-thermal";
+			dlg,tjunc-temp-polling-period-ms = <3000>;
+		};
+	};
