The immutable branch is here: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git/log/?h=ib-aspeed Yours, Linus Walleij

I'll pull it into the fsi tree so I can start laying out some of the dependent stuff on top. Cheers, Ben.
This series cleans up the register accessors a bit, adds missing ones, fixes the access to the write latch and finally adds an interface that a co-processor driver can use to change the owner of some of the GPIO lines and arbitrate access to shared GPIO banks. v2: - Address Joel comments v3: - Adds Reviewed-by tags v4: - Document the reason for including gpiolob.h - Expose GPIO offsets & bit number so coprocessor firmware doesn't have to hard-code them (allows multi-system generic firwmare that gets "configure" by the copro driver) Please consider putting this in a topic branch so I can pull it back into dependent series and point the reviewers to dependencies
