Subject[PATCH v2 00/21] MHI changes for v5.10
Date
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.
* Remove the auto-start option for MHI channels. This is done to avoid
receiving spurious uplink from MHI client device when the client driver
is not up. The corresponding qrtr change is also included with Dave's ACK.

Please consider merging!

Thanks,
Mani

Changes in v2:

* Clubbed both series (take one and two) onto a single one
* Used dev_groups to manage sysfs attributes
* Merged the debugfs fix patch with the debugfs patch
* Dropped MAX_MTU patch for now
