[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.
