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>;
|
|
};
