Subject: [PATCH v7 00/11] Introduce features and debugfs/sysfs entries for MHI
Date: Mon, 10 Aug 2020 15:00:54 -0700 [thread overview]
Message-ID: <1597096865-19636-1-git-send-email-bbhatt@codeaurora.org> (raw)
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.
v7:
-Added suggested-by and reviewed-by tags
-Fixed nitpick on removal of M3_fast counter as it was unused
-Updated sysfs documentation dates and intended kernel version
-Fixed minor debugfs formatting by removing an extra newline character
v6:
-Introduced APIs for allocating and freeing the MHI controller so as to ensure
that it is always zero-initialized
-Moved gerrits around for counter introduction
-Fixed documentation for sysfs
v5:
-Removed the debug entry to trigger reset and will be addressed in a seperate
patch
-Added patch bus: mhi: core: Use counters to track MHI device state transitions
-Updated helper API to trigger a non-blocking host resume
-Minor nitpicks also fixed
v4:
-Removed bus: mhi: core: Introduce independent voting mechanism patch
-Removed bus vote function from debugfs due to independent voting removal
-Added helper resume APIs to aid consolidation of spread out code
-Added a clean-up patch and a missing host resume in voting API
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
