This interface has limitations as it only allows to set a single opaque value called "custom_divisor". If the HW needs more complex settings (like fractional divisor) it must somehow encode this. This is horrid interface that is very driver specific and not flexible. Meanwhile Linux has established way to set free baud rate settings via BOTHER [1]. With all this being said, remove deprecated interface for good.

However, AMD data center range of processors support various system management functionality using custom protocols defined in Advanced Platform Management Link (APML) specification. Register a miscdevice, which creates a device /dev/sbrmiX with an IOCTL interface for the user space to invoke the APML Mailbox protocol, which is already defined in sbrmi_mailbox_xfer(). The APML protocols depend on a set of RMI registers. Having an IOCTL as a single entry point will help in providing synchronization among these protocols as multiple transactions on RMI register set may create race condition. Support for other protocols will be added in subsequent patches. APML mailbox protocol returns additional error codes written by SMU firmware in the out-bound register 0x37. These errors include, invalid core, message not supported over platform and others. This additional error codes can be used to provide more details to user space. Open-sourced and widely used https://github.com/amd/esmi_oob_library will continue to provide user-space programmable API.

VF device drivers (User space drivers) use this hw mailbox to communicate any required device configuration on it's respective VF device. Accordingly, this DPI PF driver provisions the VF device resources. At the hardware level, the DPI physical function (PF) acts as a management interface to setup the VF device resources, VF devices are only provisioned to handle or control the actual DMA Engine's data transfer capabilities.
