SCC (Serial Configuration Controller) is used to set initial conditions for the test chip (TC2). Its registers are also mapped in normal address space and used to obtain runtime information and for power management. Signed-off-by: Pawel Moll <pawel.moll@arm.com>

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>;
|
|
};
