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 v4.9
v4 -> v5
- Rebased from v4.8 to v4.9
- Updates from comments by Eduardo Valentin
- Replace vendor defined dlg,tjunc-temp-polling-period-ms with standard
thermal core polling-delay-passive as part of the device tree
initialisation
- Remove Acked-by Rob Herring
v3 -> v4
- NO CODE CHANGE
- Patch renamed from [PATCH V3 3/9] to [PATCH V4 2/8]
- Added Acked-by Rob Herring
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,
Updates for PATCH V5: the binding has been altered to remove the proposed
dlg,tjunc-temp-polling-period-ms and replaced with the standard thermal
core polling-delay-passive instead. This was in response to a request
from Eduardo Valentin as part of a driver change.
I have also removed a previous Ack by Rob Herring which was valid for
PATCH V3
As previously:
The device driver from this patch set (associated with this binding) is:
[PATCH V5 7/8] 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:
+
+- polling-delay-passive : Specify the polling period, measured in
+ milliseconds, between thermal zone device update checks.
+
+Example: DA9062
+
+ pmic0: da9062@58 {
+ thermal {
+ compatible = "dlg,da9062-thermal";
+ polling-delay-passive = <3000>;
+ };
+ };
+
+Example: DA9061 using a fall-back compatible for the DA9062 onkey driver
+
+ pmic0: da9061@58 {
+ thermal {
+ compatible = "dlg,da9061-thermal", "dlg,da9062-thermal";
+ polling-delay-passive = <3000>;
+ };
+ };
