- 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>;
- };
