1 OMAP GPIO controller bindings
5 - "ti,omap2-gpio" for OMAP2 controllers
6 - "ti,omap3-gpio" for OMAP3 controllers
7 - "ti,omap4-gpio" for OMAP4 controllers
8 - reg : Physical base address of the controller and length of memory mapped
10 - gpio-controller : Marks the device node as a GPIO controller.
11 - #gpio-cells : Should be two.
12 - first cell is the pin number
13 - second cell is used to specify optional parameters (unused)
14 - interrupt-controller: Mark the device node as an interrupt controller.
15 - #interrupt-cells : Should be 2.
16 The first cell is the GPIO number.
17 The second cell is used to specify flags:
18 bits[3:0] trigger type and level flags:
19 1 = low-to-high edge triggered.
20 2 = high-to-low edge triggered.
21 4 = active high level-sensitive.
22 8 = active low level-sensitive.
23 - interrupts : The interrupt the controller is rising as output when an
26 OMAP specific properties:
27 - ti,hwmods: Name of the hwmod associated to the GPIO:
28 "gpio<X>", <X> being the 1-based instance number
30 - ti,gpio-always-on: Indicates if a GPIO bank is always powered and
31 so will never lose its logic state.
