[33/46] dt-bindings:iio:adc:mediatek,mt2701-auxadc: rename and yaml conversion.

Commit Message

From: Jonathan Cameron <[e-mail]>

The current driver and indeed binding are named after a part that they
do not list in the compatible.  Hence renamed the binding to reflect
one that does.

From the driver it looks like there is a lot more backwards compatibility
than the binding currently reflects. We could consider expressing that
more explicitly in the yaml for the compatible property. I have
added one explicit pair that was present in the upstream dtsi files.

I added Matthias alongside Zhiyong Tao because I don't think
Zhiyong Tao has reviewed recent patches.  Please let me know if this
isn't the right thing to do.

+  The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
+  in some Mediatek SoCs which among other things measures the temperatures
+  in the SoC. It can be used directly with register accesses, but it is also
+  used by thermal controller which reads the temperatures from the AUXADC
+  directly via its own bus interface. See mediatek-thermal bindings
+  for the Thermal Controller which holds a phandle to the AUXADC.

-* Mediatek AUXADC - Analog to Digital Converter on Mediatek mobile soc (mt65xx/mt81xx/mt27xx)
-===============
-
-The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
-in some Mediatek SoCs which among other things measures the temperatures
-in the SoC. It can be used directly with register accesses, but it is also
-used by thermal controller which reads the temperatures from the AUXADC
-directly via its own bus interface. See
-Documentation/devicetree/bindings/thermal/mediatek-thermal.txt
-for the Thermal Controller which holds a phandle to the AUXADC.
-
-Required properties:
-  - compatible: Should be one of:
-    - "mediatek,mt2701-auxadc": For MT2701 family of SoCs
-    - "mediatek,mt2712-auxadc": For MT2712 family of SoCs
-    - "mediatek,mt6765-auxadc": For MT6765 family of SoCs
-    - "mediatek,mt7622-auxadc": For MT7622 family of SoCs
-    - "mediatek,mt8173-auxadc": For MT8173 family of SoCs
-    - "mediatek,mt8183-auxadc", "mediatek,mt8173-auxadc": For MT8183 family of SoCs
-    - "mediatek,mt8516-auxadc", "mediatek,mt8173-auxadc": For MT8516 family of SoCs
-  - reg: Address range of the AUXADC unit.
-  - clocks: Should contain a clock specifier for each entry in clock-names
-  - clock-names: Should contain "main".
-  - #io-channel-cells: Should be 1, see ../iio-bindings.txt
-
-Example:
-
-auxadc: adc@11001000 {
-	compatible = "mediatek,mt2701-auxadc";
-	reg = <0 0x11001000 0 0x1000>;
-	clocks = <&pericfg CLK_PERI_AUXADC>;
-	clock-names = "main";
-	#io-channel-cells = <1>;
-};
