Netlogic XLP Family GPIO ======================== This GPIO driver is used for following Netlogic XLP SoCs: XLP832, XLP316, XLP208, XLP980, XLP532 This GPIO driver is also compatible with GPIO controller found on Broadcom Vulcan ARM64. Required properties: ------------------- - compatible: Should be one of the following: - "netlogic,xlp832-gpio": For Netlogic XLP832 - "netlogic,xlp316-gpio": For Netlogic XLP316 - "netlogic,xlp208-gpio": For Netlogic XLP208 - "netlogic,xlp980-gpio": For Netlogic XLP980 - "netlogic,xlp532-gpio": For Netlogic XLP532 - "brcm,vulcan-gpio": For Broadcom Vulcan ARM64 - reg: Physical base address and length of the controller's registers. - #gpio-cells: Should be two. The first cell is the pin number and the second cell is used to specify optional parameters (currently unused). - gpio-controller: Marks the device node as a GPIO controller. - nr-gpios: Number of GPIO pins supported by the controller. - interrupt-cells: Should be two. The first cell is the GPIO Number. The second cell is used to specify flags. The following subset of flags is supported: - trigger type: 1 = low to high edge triggered. 2 = high to low edge triggered. 4 = active high level-sensitive. 8 = active low level-sensitive. - interrupts: Interrupt number for this device. - interrupt-parent: phandle of the parent interrupt controller. - interrupt-controller: Identifies the node as an interrupt controller. Example: gpio: xlp_gpio@34000 { compatible = "netlogic,xlp316-gpio"; reg = <0 0x34100 0x1000 0 0x35100 0x1000>; #gpio-cells = <2>; gpio-controller; nr-gpios = <57>; #interrupt-cells = <2>; interrupt-parent = <&pic>; interrupts = <39>; interrupt-controller; };
