[RFC PATCH 1/4] dt-bindings: thermal: allow more resets for tsadc node in rockchip-thermal.yaml

[Johan Jonker]

The tsadc node in rk356x.dtsi has more resets defined then currently
allowed by rockchip-thermal.yaml, so fix that in the documentation.
The driver now uses the devm_reset_control_array_get() function,
so reset-names is no longer required, but keep it for legacy reasons.

[RFC PATCH 3/4] thermal: rockchip_thermal: allow more resets for tsadc node

[Johan Jonker]

The tsadc node in rk356x.dtsi has more resets then currently
supported by the rockchip_thermal.c driver, so use
devm_reset_control_array_get() to reset them all.

[RFC PATCH 4/4] arm64: dts: fix resets in tsadc node for rk356x.dtsi

[Johan Jonker]

In the rockchip_thermal.c driver we now get the resets with
a devm_reset_control_array_get() function, so remove
the reset-names property as it is no longer needed.
Although no longer required in rockchip-thermal.yaml
sort tsadc-apb as first item.

I don't think I'd deprecate it for that reason.

And removing it would break any kernel before the 
devm_reset_control_array_get change.
