ARM Versatile Express Serial Configuration Controller |
|
----------------------------------------------------- |
|
|
|
Test chips for ARM Versatile Express platform implement SCC (Serial |
|
Configuration Controller) interface, used to set initial conditions |
|
for the test chip. |
|
|
|
In some cases its registers are also mapped in normal address space |
|
and can be used to obtain runtime information about the chip internals |
|
(like silicon temperature sensors) and as interface to other subsystems |
|
like platform configuration control and power management. |
|
|
|
Required properties: |
|
|
|
- compatible value: "arm,vexpress-scc,<model>", "arm,vexpress-scc"; |
|
where <model> is the full tile model name (as used |
|
in the tile's Technical Reference Manual), |
|
eg. for Coretile Express A15x2 A7x3 (V2P-CA15_A7): |
|
compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc"; |
|
|
|
Optional properties: |
|
|
|
- reg: when the SCC is memory mapped, physical address and size of the |
|
registers window |
|
- interrupts: when the SCC can generate a system-level interrupt |
|
|
|
Example: |
|
|
|
scc@7fff0000 { |
|
compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc"; |
|
reg = <0 0x7fff0000 0 0x1000>; |
|
interrupts = <0 95 4>; |
|
};
