Hi Greg,

Here are the MHI patches for v5.17 cycle.

Patchset summary:

1. Added support for a new PCI Foxconn modem based on Qualcomm SDX55 chipset.
This device is named as "T99W175" which was already supported but this one
seems to be using a new modem build and Foxconn is selling it as a new product
with a different PID.

2. MHI PCI generic driver now gracefully shutsdown the modem during system
freeze.

3. Used macros to identify the MHI Execution Environment (EE).

4. Fixed the comment and style issues detected by checkpatch.

5. Used dma_set_mask_and_coherent() API to simplify the code in MHI PCI generic
driver.

6. Fixed reading the "wake-capable" entry while parsing the channel
configuration structure from controller drivers.

7. Fixed the SYS_ERR handling while powering up the device. This fixes the
bootup issue with Sierra Wireless EM919X modems based on SDX55.

8. Introduced a new API for automatically queueing the buffers for the DL
channel. This patch touches QRTR driver that's under networking subsystem.
Hence, collected Ack from Jakub.

9. Used the "unsigned long" argument for find_last_bit() API. This is done to
avoid the warning with "-Warray-bounds" GCC flag.

10. Finally, added support for the Sierra Wireless EM919X modems based on
Qualcomm SDX55 chipset.

Thanks,
Mani
