* Marvell MMP Interrupt controller
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be
|
||||
"mrvl,mmp-intc" on Marvel MMP,
|
||||
"mrvl,mmp2-intc" along with "mrvl,mmp2-mux-intc" on MMP2 or
|
||||
"marvell,mmp3-intc" with "mrvl,mmp2-mux-intc" on MMP3
|
||||
- reg : Address and length of the register set of the interrupt controller.
|
||||
If the interrupt controller is intc, address and length means the range
|
||||
of the whole interrupt controller. The "marvell,mmp3-intc" controller
|
||||
also has a secondary range for the second CPU core. If the interrupt
|
||||
controller is mux-intc, address and length means one register. Since
|
||||
address of mux-intc is in the range of intc. mux-intc is secondary
|
||||
interrupt controller.
|
||||
- reg-names : Name of the register set of the interrupt controller. It's
|
||||
only required in mux-intc interrupt controller.
|
||||
- interrupts : Should be the port interrupt shared by mux interrupts. It's
|
||||
only required in mux-intc interrupt controller.
|
||||
- interrupt-controller : Identifies the node as an interrupt controller.
|
||||
- #interrupt-cells : Specifies the number of cells needed to encode an
|
||||
interrupt source.
|
||||
- mrvl,intc-nr-irqs : Specifies the number of interrupts in the interrupt
|
||||
controller.
|
||||
- mrvl,clr-mfp-irq : Specifies the interrupt that needs to clear MFP edge
|
||||
detection first.
|
||||
|
||||
Example:
|
||||
intc: interrupt-controller@d4282000 {
|
||||
compatible = "mrvl,mmp2-intc";
|
||||
interrupt-controller;
|
||||
#interrupt-cells = <1>;
|
||||
reg = <0xd4282000 0x1000>;
|
||||
mrvl,intc-nr-irqs = <64>;
|
||||
};
|
||||
|
||||
intcmux4@d4282150 {
|
||||
compatible = "mrvl,mmp2-mux-intc";
|
||||
interrupts = <4>;
|
||||
interrupt-controller;
|
||||
#interrupt-cells = <1>;
|
||||
reg = <0x150 0x4>, <0x168 0x4>;
|
||||
reg-names = "mux status", "mux mask";
|
||||
mrvl,intc-nr-irqs = <2>;
|
||||
};
|
||||
|
||||
* Marvell Orion Interrupt controller
|
||||
|
||||
Required properties
|
||||
- compatible : Should be "marvell,orion-intc".
|
||||
- #interrupt-cells: Specifies the number of cells needed to encode an
|
||||
interrupt source. Supported value is <1>.
|
||||
- interrupt-controller : Declare this node to be an interrupt controller.
|
||||
- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
|
||||
One entry in the list represents 32 interrupts.
|
||||
|
||||
Example:
|
||||
|
||||
intc: interrupt-controller {
|
||||
compatible = "marvell,orion-intc", "marvell,intc";
|
||||
interrupt-controller;
|
||||
#interrupt-cells = <1>;
|
||||
reg = <0xfed20204 0x04>,
|
||||
<0xfed20214 0x04>;
|
||||
