[PATCH v4 7/8] dt-bindings: Add 1027/1029/1031 SPI ADCs as trivial devices

[Miquel Raynal <miquel.raynal@xxxxxxxxxxx>]

In the same time, remove the dedicated bindings file which is now
useless.

-* Maxim 1027/1029/1031 Analog to Digital Converter (ADC)
-
-Required properties:
-  - compatible: Should be "maxim,max1027" or "maxim,max1029" or "maxim,max1031"
-  - reg: SPI chip select number for the device
-
-Optional properties:
-  - interrupts: IRQ line for the ADC
-  see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
-Recommended properties:
-- spi-max-frequency: Definition as per
-                     Documentation/devicetree/bindings/spi/spi-bus.txt

-Example:
-adc@0 {
-	compatible = "maxim,max1027";
-	reg = <0>;
-	interrupt-parent = <&gpio5>;
-	interrupts = <15 IRQ_TYPE_EDGE_RISING>;
-	spi-max-frequency = <1000000>;
