Subject: [PATCH 0/4] SFH: Add Support for AMD Sensor Fusion Hub

From: Sandeep Singh <sandeep.singh@....com>

AMD SFH is HID based driver. SFH FW is part of MP2
processor and it runs on MP2 where in driver resides
on X86. The driver functionalities are divided  into
three parts:-

1: amd-mp2-pcie:- This module will communicate with MP2 FW and
                   provide that data into DRAM.
2: Client driver :- This part for driver will use dram data and
                     convert that data into HID format based on
                     HID reports.
3: Transport driver :- This part of driver will communicate with
                        HID core. Communication between devices and
                        HID core is mostly done via HID reports

In terms of architecture it is much more reassembles like ISH.
However the major difference is all The hid reports are generated
as part of kernel driver. AMD SFH driver has taken reference
from ISH in terms of design and functionalities at fewer location.

AMD sensor fusion Hub is part of a SOC starting from Ryzen
based platforms. The solution is working well on windows OS
in several OEM products. AMD SFH uses HID over PCIe bus.


Sandeep Singh (4):
  SFH: Add maintainer list and documentation for AMD SFH based      on
    HID framework
  SFH: PCI driver to add support of AMD sensor fusion Hub      using HID
    framework
  SFH: Transport Driver to add support of AMD sensor fusion      Hub
    (SFH)
  SFH: Create HID report to Enable support of AMD sensor fusion Hub
    (SFH)
