Hi Greg,
Here is the MHI Pull request for the v5.13 cycle. I stayed with the PR as the
number patches got increased.
Details are in the signed tag, please consider merging!
Thanks,
Mani

bus: mhi: fix typo in comments for struct mhi_channel_config (2021-04-09 18:48:22 +0530)
----------------------------------------------------------------
MHI changes for v5.13
core:
- Added support for Flash Programmer execution environment which allows the
host machine (like x86) to flash the modem firmware to NAND or eMMC in the
modem. The MHI bus will expose EDL channels (34, 35) and then the opensource
QDL tool [1] can be used to flash the firmware from the host.
- Added an internal helper for polling the MHI registers with a retry interval.
This helper is used now to poll for the MHI ready state in MHI STATUS
register.
- Various fixes for issues found during the bringup of SDX24/SDX55 based Quectel
and Telit modems.
- Updates to the Execution environment handling for proper downloading of the
AMSS image from SBL (Secondary Bootloader) mode.
- Added support for sending STOP channel command to the MHI device and also made
changes to the MHI core for proper handling of stop and restart.
- Fixed the runtime_pm handling in the core by forcing the device to be in wake
mode until TX completion and allowing it to suspend for RX.
- Added sanity checks for values read from the device to avoid crash if those
are corrupted somehow.
- Fixed warnings generated by sparse (W=2)
- Couple of kernel doc cleanups in mhi.h
pci_generic:
- Added support for runtime PM and generic PM
- Added Firehose channels for flashing the firmware
- Added support for modems such as Quectel EM1XXGR-L, SDX24, SDX65, Foxconn
T99W175 exposing relevant channels.

A suggestion, please put [GIT PULL] in your subject line, so that I know
what this is for, that's a semi-standard thing these days.
Also, you have a number of patches in this set that look like they
should be backported to stable kernels. Any reason why you did not tag
them with a "Cc: stable@..." tag in the commit? After they are merged
into Linus's tree, please send the git ids of the commits that should go
to stable kernels to [email protected] so that we can add them
properly.
Now pulled and pushed out, thanks.
thanks,
greg k-h

Sorry, sent it a hurry so missed it.

Should've done that. Will send them once merged into mainline.
