iio: add support of the max1027
This driver add partial support of the maxim 1027/1029/1031. Differential mode is not supported. It was tested on armadeus apf27 board. Signed-off-by: Philippe Reynes <tremyfr@yahoo.fr> Reviewed-by: Hartmut Knaack <knaack.h@gmx.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

+* 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
+ - interrupt-parent: phandle to the parent interrupt controller
+ see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+ - 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>;
+};
