1Netlogic XLP Family GPIO
2========================
3
4This GPIO driver is used for following Netlogic XLP SoCs:
5	XLP832, XLP316, XLP208, XLP980, XLP532
6
7Required properties:
8-------------------
9
10- compatible: Should be one of the following:
11  - "netlogic,xlp832-gpio": For Netlogic XLP832
12  - "netlogic,xlp316-gpio": For Netlogic XLP316
13  - "netlogic,xlp208-gpio": For Netlogic XLP208
14  - "netlogic,xlp980-gpio": For Netlogic XLP980
15  - "netlogic,xlp532-gpio": For Netlogic XLP532
16- reg: Physical base address and length of the controller's registers.
17- #gpio-cells: Should be two. The first cell is the pin number and the second
18  cell is used to specify optional parameters (currently unused).
19- gpio-controller: Marks the device node as a GPIO controller.
20- nr-gpios: Number of GPIO pins supported by the controller.
21- interrupt-cells: Should be two. The first cell is the GPIO Number. The
22  second cell is used to specify flags. The following subset of flags is
23  supported:
24  - trigger type:
25	1 = low to high edge triggered.
26	2 = high to low edge triggered.
27	4 = active high level-sensitive.
28	8 = active low level-sensitive.
29- interrupts: Interrupt number for this device.
30- interrupt-parent: phandle of the parent interrupt controller.
31- interrupt-controller: Identifies the node as an interrupt controller.

33Example:
34
35	gpio: xlp_gpio@34000 {
36		compatible = "netlogic,xlp316-gpio";
37		reg = <0 0x34100 0x1000
38		       0 0x35100 0x1000>;
39		#gpio-cells = <2>;
40		gpio-controller;
41		nr-gpios = <57>;
42
43		#interrupt-cells = <2>;
44		interrupt-parent = <&pic>;
45		interrupts = <39>;
46		interrupt-controller;
47	};
