Aneesh Kumar K.V (Arm) fe7f2a8054 firmware: smccc: Add an Arm SMCCC bus ... SMCCC-discovered firmware services are currently represented by separate platform devices, such as smccc_trng and arm-cca-dev. Those devices do not represent independent DT/ACPI-described platform resources; they are features of the SMCCC firmware interface. Add an Arm SMCCC bus for services discovered through the SMCCC firmware interface. The bus provides SMCCC device and driver registration helpers, function ID based matching, modalias generation, and a sysfs modalias attribute so SMCCC service drivers can bind to discovered firmware services and autoload as modules. Follow-up changes can then register SMCCC firmware services as arm-smccc devices instead of creating independent per-feature platform devices.
