1* Altera Arria10 Development Kit System Resource Chip
2
3Required parent device properties:
4- compatible		: "altr,a10sr"
5- spi-max-frequency	: Maximum SPI frequency.
6- reg			: The SPI Chip Select address for the Arria10
7			  System Resource chip
8- interrupt-parent	: The parent interrupt controller.
9- interrupts		: The interrupt line the device is connected to.
10- interrupt-controller	: Marks the device node as an interrupt controller.
11- #interrupt-cells	: The number of cells to describe an IRQ, should be 2.
12			    The first cell is the IRQ number.
13			    The second cell is the flags, encoded as trigger
14			    masks from ../interrupt-controller/interrupts.txt.

22Arria10 GPIO
23Required Properties:
24- compatible        : Should be "altr,a10sr-gpio"
25- gpio-controller   : Marks the device node as a GPIO Controller.
26- #gpio-cells       : Should be two.  The first cell is the pin number and
27                      the second cell is used to specify flags.
28                      See ../gpio/gpio.txt for more information.
