Subject: [PATCH v1 0/6] spi-microchip-core fixes & variable word size support

Hey Mark,

Got some fixes here for the spi-microchip-core driver, that I am passing
on.. The author of the first patch is no longer at Microchip, so there's
probably gonna be some bounces on the series. The remainder of the
patches got sent in by a user, and, other than one patch, I just wrote
commit messages for those that were missing them and rebased the series
on top of mainline.

There was one other patch in the series submitted by the user to us, that
I opted to drop, adding locking around accesses to tx FIFO in the
interrupt handler and in the transfer_one implementation. I think that
patch is not needed after the first patch in this series since there'll
be no contention any more.

Cheers,
Conor.
