|
|
|
|
FPGA type interrupt controllers, see the versatile-fpga-irq binding doc.

compatible-string "arm,external-bus-interface"
|
|
|
|
Required properties for the core module:
|
|
- regs: the location and size of the core module registers, one
|
|
range of 0x200 bytes.
|
|
|
|
- syscon: the root node of the Integrator platforms must have a
|
|
system controller node pointing to the control registers,
|
|
with the compatible string
|
|
"arm,integrator-ap-syscon"
|
|
"arm,integrator-cp-syscon"
|
|
respectively.
|
|
|
|
Required properties for the system controller:

|
- regs: the location and size of the system controller registers,
|
|
one range of 0x100 bytes.
|
|

|
Required properties for the AP system controller:
|
|
- interrupts: the AP syscon node must include the logical module
|
|
interrupts, stated in order of module instance <module 0>,
|
|
<module 1>, <module 2> ... for the CP system controller this
|
|
is not required not of any use.

ARM Versatile Application and Platform Baseboards
|
|
-------------------------------------------------

|
|
core tiles. The hardware configuration of the Versatile boards is
|
|
highly customizable.
|
|
|
|
Required properties (in root node):
|
|
compatible = "arm,versatile-ab"; /* Application baseboard */

|
|
interrupt-controller;
|
|
#interrupt-cells = <1>;
|
|
|
|
- SIC required properties:

ARM RealView Boards
|
|
-------------------
|
|
The RealView boards cover tailored evaluation boards that are used to explore
|
|
the ARM11 and Cortex A-8 and Cortex A-9 processors.
|
|
|
|
Required properties (in root node):
|
|
/* RealView Emulation Baseboard */
