Merge patch series "ufs: pci: Add support UFSHCI 4.0 MCQ"
Minwoo Im <minwoo.im@samsung.com> says:
This patchset introduces add support for MCQ introduced in UFSHCI 4.0.
The first patch adds a simple helper to get the address of MCQ queue
config registers. The second one enables MCQ feature by adding mandatory
vops callback functions required at MCQ initialization phase. The last
one is to prevent a case where number of MCQ is given 1 since driver
allocates poll_queues first rather than I/O queues to handle device
commands. Instead of causing exception handlers due to no I/O queue,
failfast during the initialization time.
