CE4100 Device Tree Bindings
|
||||
---------------------------
|
||||
|
||||
The CE4100 SoC uses for in core peripherals the following compatible
|
||||
format: <vendor>,<chip>-<device>.
|
||||
Many of the "generic" devices like HPET or IO APIC have the ce4100
|
||||
name in their compatible property because they first appeared in this
|
||||
SoC.
|
||||
|
||||
The CPU node
|
||||
------------
|
||||
cpu@0 {
|
||||
device_type = "cpu";
|
||||
compatible = "intel,ce4100";
|
||||
reg = <0>;
|
||||
lapic = <&lapic0>;
|
||||
};
|
||||
|
||||
The reg property describes the CPU number. The lapic property points to
|
||||
the local APIC timer.
|
||||
|
||||
The SoC node
|
||||
------------
|
||||
|
||||
This node describes the in-core peripherals. Required property:
|
||||
compatible = "intel,ce4100-cp";
|
||||
|
||||
The PCI node
|
||||
------------
|
||||
This node describes the PCI bus on the SoC. Its property should be
|
||||
compatible = "intel,ce4100-pci", "pci";
|
||||
|
||||
If the OS is using the IO-APIC for interrupt routing then the reported
|
||||
interrupt numbers for devices is no longer true. In order to obtain the
|
||||
correct interrupt number, the child node which represents the device has
|
||||
to contain the interrupt property. Besides the interrupt property it has
|
||||
to contain at least the reg property containing the PCI bus address and
|
||||
compatible property according to "PCI Bus Binding Revision 2.1".

Interrupt chips

---------------

* Intel I/O Advanced Programmable Interrupt Controller (IO APIC)
|

|

Required properties:
|

--------------------
|

compatible = "intel,ce4100-ioapic";
|

#interrupt-cells = <2>;
|

|
||||
Device's interrupt property:
|
||||
|
||||
interrupts = <P S>;
|
||||
|
||||
The first number (P) represents the interrupt pin which is wired to the
|
||||
IO APIC. The second number (S) represents the sense of interrupt which
|
||||
should be configured and can be one of:
|
||||
0 - Edge Rising
|
||||
1 - Level Low
|
||||
2 - Level High
|
||||
3 - Edge Falling
|
||||
|
||||
* Local APIC
|
||||
Required property:
|
||||
|
||||
compatible = "intel,ce4100-lapic";
