Merge tag 'fsi-updates-2018-07-24' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/linux-fsi into char-misc-testing
Ben writes: This adds support for offloading the FSI low level bitbanging to the ColdFire coprocessor of the Aspeed SoCs. All the pre-requisites have already been merged, this is the final piece in the puzzle. This branch also pull gpio/ib-aspeed which is a topic branch already in gpio/for-next (and thus in next) whic contains pre-requisites. Finally, there's also a bug fix to the sbefifo driver for some inconsistent use of a mutex in the error handling code.
