Linus Torvalds e86dda7bde spi: Updates for v7.0
The highlight here is that David Lechner has added support for multi-lane
 SPI devices.  Unlike the existing dual/quad SPI support this is for
 devices (typically ADCs/DACs) which support multiple independent data
 streams over multiple data lanes, instead of sending one data stream N
 times as fast they simultaneously transfer N different data streams.
 This is very similar to the case where multiple devices are grouped
 together but in this case it's a single device in a way that's visible
 to software.
 
 Otherwise there's been quite a bit of work on existing drivers, both
 cleanup and feature improvement, and a reasonable collection of new
 drivers.
 
  - Support for multi-lane SPI devices.
  - Preparatory work for some memory mapped flash improvements that will
    happen in the MTD subsystem.
  - Several conversions to fwnode APIs.
  - A bunch of cleanup and hardening work on the ST drivers.
  - Support for DMA mode on Renesas RZV2H and i.MX target mode.
  - Support for ATCSPI200, AXIADO AX300, NXP XPI and Renesas RZ/N1.
