[PATCH v3 0/5] SFH: Add Support for AMD Sensor Fusion Hub

[Sandeep Singh]

From: Sandeep Singh <sandeep.singh@xxxxxxx>

AMD SFH(Sensor Fusion Hub) is HID based driver.SFH FW 
is part of MP2 processor (MP2 which is an ARMÂ Cortex-M4 
core based co-processor to x86) 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(Intel Integrated Sensor Hub). However the major difference 
is all the hid reports are generated as part of kernel driver. 
AMD SFH driver taken reference from ISH in terms of 
design and functionalities at fewer location.

AMD sensor fusion Hub is part of a SOC 17h family based platforms. 
The solution is working well on several OEM products.
AMD SFH uses HID over PCIe bus.


Sandeep Singh (5):
  SFH: Add maintainers 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: Add debugfs support to AMD Sensor Fusion Hub
  SFH: Create HID report to Enable support of AMD sensor fusion Hub
    (SFH)
