* Microsemi MIPS CPUs
|
||
|
|
|
||
|
|
Boards with a SoC of the Microsemi MIPS family shall have the following
|
||
|
|
properties:
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "mscc,ocelot", "mscc,luton", "mscc,serval" or "mscc,jr2"
|
||
|
|
|
||
|
|
|
||
|
|
* Other peripherals:
|
||
|
|
|
||
|
|
o CPU chip regs:
|
||
|
|
|
||
|
|
The SoC has a few registers (DEVCPU_GCB:CHIP_REGS) handling miscellaneous
|
||
|
|
functionalities: chip ID, general purpose register for software use, reset
|
||
|
|
controller, hardware status and configuration, efuses.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "mscc,ocelot-chip-regs", "simple-mfd", "syscon"
|
||
|
|
- reg : Should contain registers location and length
|
||
|
|
|
||
|
|
Example:
|
||
|
|
syscon@71070000 {
|
||
|
|
compatible = "mscc,ocelot-chip-regs", "simple-mfd", "syscon";
|
||
|
|
reg = <0x71070000 0x1c>;
|
||
|
|
};
|
||
|
|
|
||
|
|
|
||
|
|
o CPU system control:
|
||
|
|
|
||
|
|
The SoC has a few registers (ICPU_CFG:CPU_SYSTEM_CTRL) handling configuration of
|
||
|
|
the CPU: 8 general purpose registers, reset control, CPU en/disabling, CPU
|
||
|
|
endianness, CPU bus control, CPU status.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "mscc,ocelot-cpu-syscon", "syscon"
|
||
|
|
- reg : Should contain registers location and length
|
||
|
|
|
||
|
|
Example:
|
||
|
|
syscon@70000000 {
|
||
|
|
compatible = "mscc,ocelot-cpu-syscon", "syscon";
|
||
|
|
reg = <0x70000000 0x2c>;
|
||
|
|
};
|
||
|
|
|
||
|
|
o HSIO regs:
|
||
|
|
|
||
|
|
The SoC has a few registers (HSIO) handling miscellaneous functionalities:
|
||
|
|
configuration and status of PLL5, RCOMP, SyncE, SerDes configurations and
|
||
|
|
status, SerDes muxing and a thermal sensor.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "mscc,ocelot-hsio", "syscon", "simple-mfd"
|
||
|
|
- reg : Should contain registers location and length
|
||
|
|
|
||
|
|
Example:
|
||
|
|
syscon@10d0000 {
|
||
|
|
compatible = "mscc,ocelot-hsio", "syscon", "simple-mfd";
|
||
|
|
reg = <0x10d0000 0x10000>;
|
||
|
|
};
