MHI Host
========

Core
----

- Skipped MHI reset if the device is in RDDM EE (Ramdump mode) since the device
  cannot process reset request.

- Updated the sysfs contact details to use MHI list instead of bouncing
  codeaurora email ids.

- Added support to allow MHI client drivers to provide the device firmware via
  a pointer. This is required to support new firmware format to be used by
  ath11k drivers.

- Used vcalloc instead of vzalloc to protect against multiplication overflows.

- Removed decrementing one unused parameter.

pci_generic
-----------

- Added support for MHI SW channels (IP_SW0) so that the host can transfer data
  from devices over networking interface through this specific channel.

- Added support for a clone of Quectel RM520N-GL modem which uses a different
  PID as it is targeted for laptop usecase.

- Added support for a clone of Quectel EM160R-GL modem which uses a different
  PID as it is targeted for laptop usecase.

- Added support for another clone of Quectel RM520N-GL modem which uses a
  different PID as it is targeted for Lenovo laptop usecase.

- Added support for Dell DW5932e modem (both eSIM and non-eSIM variants).

- Added support for Telit FE990 modem.
