[PATCH 1/3] dt-bindings: iio: adc: maxim,max11100 yaml conversion

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Straight forward conversion for this SPI ADC.
Added limits on spi-max-frequency from datasheet (0.1 to 4.8MHz)

-* Maxim max11100 Analog to Digital Converter (ADC)
-
-Required properties:
-  - compatible: Should be "maxim,max11100"
-  - reg: the adc unit address
-  - vref-supply: phandle to the regulator that provides reference voltage
-
-Optional properties:
-  - spi-max-frequency: SPI maximum frequency
-
-Example:
-
-max11100: adc@0 {
-        compatible = "maxim,max11100";
-        reg = <0>;
-        vref-supply = <&adc0_vref>;
-        spi-max-frequency = <240000>;
