4 - compatible:
5   - "altr,pio-1.0"
6 - reg: Physical base address and length of the controller's registers.
9 - altr,gpio-bank-width: Width of the GPIO bank. This defines how many pins the
10   GPIO device has. Ranges between 1-32. Optional and defaults to 32 if not
12 - gpio-bank-name: bank name attached to this device.
16 user_led_pio_8out: gpio@0x4cc0 {
17 	compatible = "altr,pio-1.0";
20 	altr,gpio-bank-width = <8>;
21 	#gpio-cells = <2>;
22 	gpio-controller;
23 	gpio-bank-name = "led";
26 In this example, the gpio can be accessed as led[0..7] using gpio command of
27 u-boot.
