Subject: [PATCH v3 0/7] Introduce features and debugfs/sysfs entries for MHI
Date:   Mon, 18 May 2020 13:03:54 -0700
Message-Id: <1589832241-13867-1-git-send-email-bbhatt@codeaurora.org>

Precedence: bulk

Introduce independent bus and device voting mechanism for clients and save
hardware information from BHI.
Allow reading and modifying some MHI variables for debug, test, and
informational purposes using debugfs.
Read values for device specific hardware information to be used by OEMs in
factory testing such as serial number and PK hash using sysfs.

This set of patches was tested on arm64 and x86.

v3:
-Add patch to check for pending packets in suspend as a dependency for the
independent voting mechanism introduction
-Include register dump entry for debugfs to dump MHI, BHI, and BHIe registers
-Update commit message for the debugfs patch
-Updated Documentation/ABI with the required info for sysfs
-Updated debugfs patch to include a new KConfig entry and dependencies
-Updated reviewed-by for some patches

v2:
-Added a new debugfs.c file for specific debugfs entries and code
-Updated commit text and addressed some comments for voting change
-Made sure sysfs is only used for serial number and OEM PK hash usage

Bhaumik Bhatt (7):
  bus: mhi: core: Abort suspends due to outgoing pending packets
  bus: mhi: core: Introduce independent voting mechanism
  bus: mhi: core: Use generic name field for an MHI device
  bus: mhi: core: Introduce helper function to check device state
  bus: mhi: core: Introduce debugfs entries and counters for MHI
  bus: mhi: core: Read and save device hardware information from BHI
  bus: mhi: core: Introduce sysfs entries for MHI
