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. Signed-off-by: Steve Twiss Acked-by: Rob Herring --- 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 Regards, Steve Twiss, Dialog Semiconductor Ltd. .../devicetree/bindings/thermal/da9062-thermal.txt | 37 ++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 Documentation/devicetree/bindings/thermal/da9062-thermal.txt diff --git a/Documentation/devicetree/bindings/thermal/da9062-thermal.txt b/Documentation/devicetree/bindings/thermal/da9062-thermal.txt new file mode 100644 index 0000000..08cc72e --- /dev/null +++ b/Documentation/devicetree/bindings/thermal/da9062-thermal.txt @@ -0,0 +1,37 @@ +* Dialog DA9062/61 TJUNC Thermal Module + +This module is part of the DA9061/DA9062.
