[PATCH 0/2] hwmon: Add Axiado AX3000 TSADC driver

[Petar Stepanovic]

This series adds support for the temperature sensor ADC (TSADC)
controller found on the Axiado AX3000 and AX3005 SoCs. The controller
measures temperature at locations within the SoC silicon die.

AX3005 uses the same programming model as AX3000 and uses
"axiado,ax3000-tsadc" as its fallback compatible.

Each TSADC controller is represented by a separate Devicetree node and
registered as a separate hwmon device exposing one read-only temperature
channel.

The sensor is configured for continuous conversion during probe. The
averaged 12-bit ADC code is converted to millidegrees Celsius using a
lookup table with linear interpolation between adjacent entries. Raw
values outside the characterized lookup-table range are clamped to the
nearest supported temperature.

[PATCH 1/2] dt-bindings: hwmon: Add Axiado AX3000 TSADC

[Petar Stepanovic]

Add a Devicetree binding for the temperature sensor ADC (TSADC)
controller found on the Axiado AX3000 and AX3005 SoCs.

The controller monitors the on-die temperature. An SoC may contain
multiple TSADC controllers at different locations on the die, each
represented by a separate Devicetree node.

AX3005 uses the same programming model as AX3000 and is compatible
with the AX3000 implementation. Therefore, axiado,ax3000-tsadc is
used as its fallback compatible.

Also add a MAINTAINERS entry covering the binding and driver.

[PATCH 2/2] hwmon: axiado-tsadc: Add AX3000/AX3005 TSADC support

[Petar Stepanovic]

Add a hwmon driver for the temperature sensor ADC (TSADC) controller
found on Axiado AX3000 and AX3005 SoCs. The controller measures
temperature at locations within the SoC silicon die.

Each TSADC controller is registered as a separate hwmon device and
exposes one read-only temperature channel. The sensor is configured for
continuous conversion during probe.

The current TSADC hardware does not support threshold or alarm reporting.
All TSADC interrupt sources are masked during initialization, and only
the current temperature is exposed through temp1_input.

The averaged 12-bit ADC code is converted to millidegrees Celsius using
a lookup table with linear interpolation between adjacent entries. Raw
values outside the characterized lookup-table range are clamped to the
nearest supported temperature.

+Description
+-----------
+
+This driver supports the Temperature Sensor ADC (TSADC) block found on Axiado
+AX3000 and AX3005 SoCs. The block monitors the on-die temperature of the SoC.
+
+An SoC may instantiate several TSADC blocks at different locations on the die.
+Each block is described by its own device tree node and is registered as a
+separate hwmon device with a single temperature channel.
+
+The sensor is configured for continuous conversion at probe time, averaging
+16 samples per conversion. The averaged 12-bit ADC code is converted to
+millidegrees Celsius using a lookup table with linear interpolation between
+entries. The table covers -40 to +125 degrees Celsius; readings outside that
+range are clamped to the nearest supported temperature.

Re: [PATCH 1/2] dt-bindings: hwmon: Add Axiado AX3000 TSADC

[sashiko-bot]

> Add a Devicetree binding for the temperature sensor ADC (TSADC)
> controller found on the Axiado AX3000 and AX3005 SoCs.
> 
> The controller monitors the on-die temperature. An SoC may contain
> multiple TSADC controllers at different locations on the die, each
> represented by a separate Devicetree node.
> 
> AX3005 uses the same programming model as AX3000 and is compatible
> with the AX3000 implementation. Therefore, axiado,ax3000-tsadc is
> used as its fallback compatible.

Re: [PATCH 2/2] hwmon: axiado-tsadc: Add AX3000/AX3005 TSADC support

> Add a hwmon driver for the temperature sensor ADC (TSADC) controller

> 
> Each TSADC controller is registered as a separate hwmon device and
> exposes one read-only temperature channel. The sensor is configured for
> continuous conversion during probe.
> 
> The current TSADC hardware does not support threshold or alarm reporting.
> All TSADC interrupt sources are masked during initialization, and only
> the current temperature is exposed through temp1_input.
> 
> The averaged 12-bit ADC code is converted to millidegrees Celsius using
> a lookup table with linear interpolation between adjacent entries. Raw
> values outside the characterized lookup-table range are clamped to the
> nearest supported temperature.
