Merge tag 'spi-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity.
This includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the
memory subsystem doesn't seem to have a fixed maintainer at the minute
and this seemed like the most sensible way to get that hardware
supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm
GENI, sun6i and lantiq drivers.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1"
