-Broadcom STB "UPG GIO" GPIO controller
-
-The controller's registers are organized as sets of eight 32-bit
-registers with each set controlling a bank of up to 32 pins. A single
-interrupt is shared for all of the banks handled by the controller.
-
-Required properties:
-
-- compatible:
- Must be "brcm,brcmstb-gpio"
-
-- reg:
- Define the base and range of the I/O address space containing
- the brcmstb GPIO controller registers
-
-- #gpio-cells:
- Should be <2>. The first cell is the pin number (within the controller's
- pin space), and the second is used for the following:
- bit[0]: polarity (0 for active-high, 1 for active-low)
-
-- gpio-controller:
- Specifies that the node is a GPIO controller.
-
-- brcm,gpio-bank-widths:
- Number of GPIO lines for each bank. Number of elements must
- correspond to number of banks suggested by the 'reg' property.
-
-Optional properties:
-
-- interrupts:
- The interrupt shared by all GPIO lines for this controller.
-
-- interrupts-extended:
- Alternate form of specifying interrupts and parents that allows for
- multiple parents. This takes precedence over 'interrupts' and
- 'interrupt-parent'. Wakeup-capable GPIO controllers often route their
- wakeup interrupt lines through a different interrupt controller than the
- primary interrupt line, making this property necessary.
-
-- #interrupt-cells:
- Should be <2>. The first cell is the GPIO number, the second should specify
- flags. The following subset of flags is supported:
- - bits[3:0] trigger type and level flags
- 1 = low-to-high edge triggered
- 2 = high-to-low edge triggered
- 4 = active high level-sensitive
- 8 = active low level-sensitive
- Valid combinations are 1, 2, 3, 4, 8.
- See also Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
-- interrupt-controller:
- Marks the device node as an interrupt controller
-
-- wakeup-source:
- GPIOs for this controller can be used as a wakeup source
-
-Example:
- upg_gio: gpio@f040a700 {
- #gpio-cells = <2>;
- #interrupt-cells = <2>;
- compatible = "brcm,bcm7445-gpio", "brcm,brcmstb-gpio";
- gpio-controller;
- interrupt-controller;
- reg = <0xf040a700 0x80>;
- interrupt-parent = <&irq0_intc>;
- interrupts = <0x6>;
- brcm,gpio-bank-widths = <32 32 32 24>;
- };
-
- upg_gio_aon: gpio@f04172c0 {
- #gpio-cells = <2>;
- #interrupt-cells = <2>;
- compatible = "brcm,bcm7445-gpio", "brcm,brcmstb-gpio";
- gpio-controller;
- interrupt-controller;
- reg = <0xf04172c0 0x40>;
- interrupt-parent = <&irq0_aon_intc>;
- interrupts = <0x6>;
- interrupts-extended = <&irq0_aon_intc 0x6>,
- <&aon_pm_l2_intc 0x5>;
- wakeup-source;
- brcm,gpio-bank-widths = <18 4>;
- };
