[PATCH v3 00/19] MHI changes for v5.10

[Manivannan Sadhasivam]

Hi Greg,

Here is the MHI series for v5.10 cycle. Most of the patches are cleanups
in the MHI stack. Notable changes are below:

* Saving the client device hardware information obtained through the BHI
  protocol. This information will be exposed through sysfs to make use in
  the userland applications.
* Introduce sysfs entries to read the serial number and OEM PK hash values
  of the client device obtained from BHI protocol. Relevant API documentation
  is also added.
* Introduce debugfs entries to show MHI states, events, channels, register
  state etc... to aid debug.
* Remove the channel name from MHI device name as the device is not specific
  to channels. Used generic names instead!
* Fix the warning reported by Kbuild bot by using append (+=) Kbuild rule
  to the mhi/core Makefile.
* Introduce APIs to allocate and free MHI controllers. This is done to make
  sure that the allocated structs are initialized to NULL before passing to
  the MHI core.
* Remove the requirement to have a dedicated IRQ for each event ring.
  The MHI controllers can now use a single IRQ for all event rings.

Please consider merging!

Thanks,
Mani
