1 Netlogic XLP Family GPIO
2 ========================
4 This GPIO driver is used for following Netlogic XLP SoCs:
5 XLP832, XLP316, XLP208, XLP980, XLP532
6 This GPIO driver is also compatible with GPIO controller found on
12 - compatible: Should be one of the following:
13 - "netlogic,xlp832-gpio": For Netlogic XLP832
14 - "netlogic,xlp316-gpio": For Netlogic XLP316
15 - "netlogic,xlp208-gpio": For Netlogic XLP208
16 - "netlogic,xlp980-gpio": For Netlogic XLP980
17 - "netlogic,xlp532-gpio": For Netlogic XLP532
18 - "brcm,vulcan-gpio": For Broadcom Vulcan ARM64
19 - reg: Physical base address and length of the controller's registers.
20 - #gpio-cells: Should be two. The first cell is the pin number and the second
21 cell is used to specify optional parameters (currently unused).
22 - gpio-controller: Marks the device node as a GPIO controller.
23 - nr-gpios: Number of GPIO pins supported by the controller.
24 - interrupt-cells: Should be two. The first cell is the GPIO Number. The
25 second cell is used to specify flags. The following subset of flags is
28 1 = low to high edge triggered.
29 2 = high to low edge triggered.
30 4 = active high level-sensitive.
31 8 = active low level-sensitive.
32 - interrupts: Interrupt number for this device.
33 - interrupt-controller: Identifies the node as an interrupt controller.
