1ARM Versatile Express Serial Configuration Controller 2----------------------------------------------------- 3 4Test chips for ARM Versatile Express platform implement SCC (Serial 5Configuration Controller) interface, used to set initial conditions 6for the test chip. 7 8In some cases its registers are also mapped in normal address space 9and can be used to obtain runtime information about the chip internals 10(like silicon temperature sensors) and as interface to other subsystems 11like platform configuration control and power management. 12 13Required properties: 14 15- compatible value: "arm,vexpress-scc,<model>", "arm,vexpress-scc"; 16 where <model> is the full tile model name (as used 17 in the tile's Technical Reference Manual), 18 eg. for Coretile Express A15x2 A7x3 (V2P-CA15_A7): 19 compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc"; 20 21Optional properties: 22 23- reg: when the SCC is memory mapped, physical address and size of the 24 registers window 25- interrupts: when the SCC can generate a system-level interrupt 26 27Example: 28 29 scc@7fff0000 { 30 compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc"; 31 reg = <0 0x7fff0000 0 0x1000>; 32 interrupts = <0 95 4>; 33 };
