- #gpio-cells: Should be <2>. The first cell is the pin number and the
- #interrupt-cells: Should be two.
- interrupts: Interrupt specifier for the controller's Broadway (PowerPC)
interrupt.
- - interrupt-parent: phandle of the parent interrupt controller.
Example:
Required properties:
- compatible : must be "hideep,hideep-ts"
- reg : I2C slave address, (e.g. 0x6C).
- - interrupt-parent : Interrupt controller to which the chip is connected.
- interrupts : Interrupt to which the chip is connected.
Optional properties:
reg = <0x6c>;
interrupt-parent = <&gpx1>;
interrupts = <2 IRQ_TYPE_LEVEL_LOW>;
- vdd-supply = <&ldo15_reg>";
+ vdd-supply = <&ldo15_reg>;
vid-supply = <&ldo18_reg>;

- compatible : should be "ingenic,<socname>-intc". Valid strings are:
ingenic,jz4740-intc
+ ingenic,jz4725b-intc
ingenic,jz4770-intc
ingenic,jz4775-intc
ingenic,jz4780-intc
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source. The value shall be 1.
- - interrupt-parent : phandle of the CPU interrupt controller.
- interrupts : Specifies the CPU interrupt the controller is connected to.
Example:
include "nvidia,tegra30-ictlr".
- reg : Specifies base physical address and size of the registers.
Each controller must be described separately (Tegra20 has 4 of them,
- whereas Tegra30 and later have 5"
+ whereas Tegra30 and later have 5).
- interrupt-controller : Identifies the node as an interrupt controller.
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source. The value must be 3.
- - interrupt-parent : a phandle to the GIC these interrupts are routed
- to.
Notes:
A. External GPIO Interrupts: For supporting external gpio interrupts, the
following properties should be specified in the pin-controller device node.
- - interrupt-parent: phandle of the interrupt parent to which the external
- GPIO interrupts are forwarded to.
- interrupts: interrupt specifier for the controller. The format and value of
the interrupt specifier depends on the interrupt parent for the controller.
B. External Wakeup Interrupts: For supporting external wakeup interrupts, a
child node representing the external wakeup interrupt controller should be
- included in the pin-controller device node. This child node should include
- the following properties.
+ included in the pin-controller device node.
+
+ Only one pin-controller device node can include external wakeup interrupts
+ child node (in other words, only one External Wakeup Interrupts
+ pin-controller is supported).
+
+ This child node should include following properties:
- compatible: identifies the type of the external wakeup interrupt controller
The possible values are:
found on Samsung S3C2412 and S3C2413 SoCs,
- samsung,s3c64xx-wakeup-eint: represents wakeup interrupt controller
found on Samsung S3C64xx SoCs,
+ - samsung,s5pv210-wakeup-eint: represents wakeup interrupt controller
+ found on Samsung S5Pv210 SoCs,
- samsung,exynos4210-wakeup-eint: represents wakeup interrupt controller
found on Samsung Exynos4210 and S5PC110/S5PV210 SoCs.
- samsung,exynos7-wakeup-eint: represents wakeup interrupt controller
found on Samsung Exynos7 SoC.
- - interrupt-parent: phandle of the interrupt parent to which the external
- wakeup interrupts are forwarded to.
- interrupts: interrupt used by multiplexed wakeup interrupts.
In addition, following properties must be present in node of every bank
Node of every bank of pins supporting direct wake-up interrupts (without
multiplexing) must contain following properties:
- - interrupt-parent: phandle of the interrupt parent to which the external
- wakeup interrupts are forwarded to.
- interrupts: interrupts of the interrupt parent which are used for external
wakeup interrupts from pins of the bank, must contain interrupts for all
pins of the bank.
Optional properties:
- reset: : Reference to the reset controller
- - interrupt-parent: phandle of the interrupt parent to which the external
- GPIO interrupts are forwarded to.
- - st,syscfg: Should be phandle/offset pair. The phandle to the syscon node
- which includes IRQ mux selection register, and the offset of the IRQ mux
- selection register.
+ - st,syscfg: Should be phandle/offset/mask.
+ -The phandle to the syscon node which includes IRQ mux selection register.
+ -The offset of the IRQ mux selection register
+ -The field mask of IRQ mux, needed if different of 0xf.
- gpio-ranges: Define a dedicated mapping between a pin-controller and
a gpio controller. Format is <&phandle a b c> with:
-(phandle): phandle of pin-controller.
NOTE: If "gpio-ranges" is used for a gpio controller, all gpio-controller
have to use a "gpio-ranges" entry.
More details in Documentation/devicetree/bindings/gpio/gpio.txt.
+ - st,bank-ioport: should correspond to the EXTI IOport selection (EXTI line
+ used to select GPIOs as interrupts).
