-* Meta External Trigger Controller Binding
-
-This binding specifies what properties must be available in the device tree
-representation of a Meta external trigger controller.
-
-Required properties:
-
- - compatible: Specifies the compatibility list for the interrupt controller.
- The type shall be <string> and the value shall include "img,meta-intc".
-
- - num-banks: Specifies the number of interrupt banks (each of which can
- handle 32 interrupt sources).
-
- - interrupt-controller: The presence of this property identifies the node
- as an interrupt controller. No property value shall be defined.
-
- - #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The type shall be a <u32> and the value shall be 2.
-
- - #address-cells: Specifies the number of cells needed to encode an
- address. The type shall be <u32> and the value shall be 0. As such,
- 'interrupt-map' nodes do not have to specify a parent unit address.
-
-Optional properties:
-
- - no-mask: The controller doesn't have any mask registers.
-
-* Interrupt Specifier Definition
-
- Interrupt specifiers consists of 2 cells encoded as follows:
-
- - <1st-cell>: The interrupt-number that identifies the interrupt source.
-
- - <2nd-cell>: The Linux interrupt flags containing level-sense information,
- encoded as follows:
- 1 = edge triggered
- 4 = level-sensitive
-
-* Examples
-
-Example 1:
-
- /*
- * Meta external trigger block
- */
- intc: intc {
- // This is an interrupt controller node.
- interrupt-controller;
-
- // No address cells so that 'interrupt-map' nodes which
- // reference this interrupt controller node do not need a parent
- // address specifier.
- #address-cells = <0>;
-
- // Two cells to encode interrupt sources.
- #interrupt-cells = <2>;
-
- // Number of interrupt banks
- num-banks = <2>;
-
- // No HWMASKEXT is available (specify on Chorus2 and Comet ES1)
- no-mask;
-
- // Compatible with Meta hardware trigger block.
- compatible = "img,meta-intc";
- };
-
-Example 2:
-
- /*
- * An interrupt generating device that is wired to a Meta external
- * trigger block.
- */
- uart1: uart@...04c00 {
- // Interrupt source '5' that is level-sensitive.
- // Note that there are only two cells as specified in the
- // interrupt parent's '#interrupt-cells' property.
- interrupts = <5 4 /* level */>;
-
- // The interrupt controller that this device is wired to.
- interrupt-parent = <&intc>;
- };
