[PATCH 00/17] mtd: rawnand: cafe: Convert to exec_op() (and more)

[Boris Brezillon <boris.brezillon@xxxxxxxxxxxxx>]

Hello,

A bit of context to explain the motivation behind those conversions
I've been sending for the last couple of weeks. The raw NAND subsystem
carries a lot of history which makes any rework not only painful, but
also subject to regressions which we only detect when someone dares to
update its kernel on one of those ancient HW. While carrying drivers
for old HW is not a problem per se, carrying ancient and unmaintained
drivers that are not converted to new APIs is a maintenance burden,
hence this massive conversion attempt I'm conducting here.

So here it is, a series converting the CAFE NAND controller driver to
exec_op(), plus a bunch of minor improvements done along the way.
I hope I'll find someone to test those changes, but if there's no one
still owning OLPC HW or no interest in keeping it supported in recent
kernel versions, we should definitely consider removing the driver
instead.

Regards,

Boris
