fsi: occ: Add support for P10

2020-12-11T15:42:27Z

The P10 OCC has a different SRAM address for the command and response buffers. In addition, the SBE commands to access the SRAM have changed format. Add versioning to the driver to handle these differences.

fsi: Aspeed: Add mutex to protect HW access

2020-12-09T18:52:25Z

There is nothing to prevent multiple commands being executed simultaneously. Add a mutex to prevent this.

fsi: aspeed: Support CFAM reset GPIO

2020-09-10T02:56:43Z

Systems have a line for restting the remote CFAM. This is not part of the FSI master, but is associated with it, so it makes sense to include it in the master driver. This exposes a sysfs interface to reset the cfam, abstracting away the direction and polarity of the GPIO, as well as the timing of the reset pulse. Userspace will be blocked until the reset pulse is finished. The reset is hard coded to be in the range of (900, 1000) us. It was observed with a scope to regularly be just over 1ms. If the device tree property is not preset the driver will silently continue.

fsi: aspeed: Add module param for bus divisor

2020-09-10T02:53:19Z

For testing and hardware debugging a user may wish to override the divisor at runtime. By setting fsi_master_aspeed.bus_div=N, the divisor will be set to N, if 0 < N <= 0x3ff. This is a module parameter and not a device tree option as it will only need to be set when testing or debugging.

fsi: aspeed: Run the bus at maximum speed

2020-09-10T02:53:17Z

Testing of Tacoma has shown that the ASPEED master can be run at maximum speed. The exception is when wired externally with a cable, in which case we use a divisor of two to ensure reliable operation.

fsi: aspeed: Support cabled FSI

2020-09-10T02:53:14Z

Some FSI capable systems have internal FSI signals, and some have external cabled FSI. Software can detect which machine this is by reading a jumper GPIO, and also control which pins the signals are routed to through a mux GPIO. This attempts to find the GPIOs at probe time. If they are not present in the device tree the driver will not error and continue as before. The mux GPIO is owned by the FSI driver to ensure it is not modified at runtime. The routing jumper obtained as non-exclusive to allow other software to inspect it's state.
