[PATCH v1 0/5] microchip core-qspi gpio-cs fixes + cleanup

[Conor Dooley]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

Hey Mark,

Got a couple of patches here, the first two deal with an issue that a
customer reported where using a mixed configuration of the built-in chip
select and a gpio lead to data corruption. Turned out, the built-in chip
select always gets activated at the moment even if a gpio-cs is being
used. With that fixed, I noticed that any read with multiple data lines
was not working properly, so patch two changes how the driver deals with
emulating mem-ops. The remaining patches are things I consider fixes but
not meaningful enough to get a Fixes tag. LMK if you want em split out
to be put on for-next rather than for-current.

Cheers,
Conor.

    instead of which controller
