I gave this a test too on my db820c. Usually the board MSS will crash 
after ~0.1 - 0.15 seconds after booting up, then during recovery the 
board will crash/reboot somewhere at the end of q6v5_mss_load() (and 
typically after successful q6v5_rmb_mba_wait() call.

Occasionally (approximately 1 of 20) the MSS will not crash, presenting 
PDS service to the userspace. Even in this state it doesn't seem to be 
able to lock the gps location (but this might be related to the big UART 
mezzanine sitting on top of the board).

Unfortunately there seem to be no SLPI firmware for the db820c, so I can 
not test slpi.

A notice regarding the patchset itself. It looks like pil_q6v5_mss.c 
driver misses mx and cx proxy power domains for the MSS_MSM8996 case.
