  bus: mhi: host: Add support for Foxconn T99W373 and T99W368 (2022-05-10 11:10:56 +0530)

----------------------------------------------------------------
MHI changes for v5.19

MHI Host
--------

Support for new modems:

 - Foxconn Cinterion MV32-WA/MV32-WB based on SDX62/SDX65
 - Telit FN980 v1 based on SDX55
 - Telit FN990 based on SDX65
 - Foxconn T99W373/T99W368 based on SDX62/SDX65

Core changes:

 - During the recycle of event ring elements, compute the ctxt_wp based on the
   local cached value instead of reading from shared memory. This is to prevent
   the possible corruption of the ctxt_wp as some of the endpoint devices could
   modify the value in shared memory.

 - Add sysfs support for resetting the endpoint based on the MHI spec. The MHI
   spec allows the host to hard reset the device in the case of an unrecoverable
   error and all other reset mechanisms have failed.

 - During MHI shutdown, wait for the endpoint device to enter the ready state
   post reset before proceeding. This is to avoid a possible race where host
   would remove the interrupt handler and device will send ready state
   interrupt, resulting in IOMMU fault.

 - Bail out updating the MHI register if the read has failed during
   read/modify/write.

 - Use mhi_write_reg() instead of mhi_write_reg_field() for writing the whole
   register fields in mhi_init_mmio().

MAINTAINERS change:

 - Since Qualcomm has moved the email domain for its employess from codeaurora
   domain to quicinc, update the same for Hemant.
