1 Davinci/Keystone GPIO controller bindings
4 - compatible: should be "ti,dm6441-gpio": for Davinci da850 SoCs
5 			"ti,keystone-gpio": for Keystone 2 66AK2H/K, 66AK2L,
7 			"ti,k2g-gpio", "ti,keystone-gpio": for 66AK2G
8 			"ti,am654-gpio", "ti,keystone-gpio": for TI K3 AM654
9 			"ti,j721e-gpio", "ti,keystone-gpio": for J721E SoCs
11 - reg: Physical base address of the controller and the size of memory mapped
14 - gpio-controller : Marks the device node as a gpio controller.
16 - #gpio-cells : Should be two.
17   - first cell is the pin number
18   - second cell is used to specify optional parameters (unused)
20 - interrupts: Array of GPIO interrupt number. Only banked or unbanked IRQs are
23 - ti,ngpio: The number of GPIO pins supported.
25 - ti,davinci-gpio-unbanked: The number of GPIOs that have an individual interrupt
28 - clocks: Should contain the device's input clock, and should be defined as per
31           Documentation/devicetree/bindings/clock/keystone-gate.txt
34           Documentation/devicetree/bindings/clock/ti,sci-clk.txt
37 - clock-names: Name should be "gpio";
39 Currently clock-names and clocks are needed for all keystone 2 platforms
42 The GPIO controller also acts as an interrupt controller. It uses the default
44 interrupt-controller/interrupts.txt.
