This series adds a new ufs vops to allow platform specific methods for resetting an attached UFS device, then implements this for the Qualcomm driver. This reset seems to be necessary for the majority of Dragonboard845c devices. Bean requested in v3 that a software fallback mechanism, using UIC_CMD_DME_END_PT_RST. I have not been successful in validating that this works for me, so I'm postponing this effort and hoping we can add it incrementally at a later time.
