Linus Torvalds 0805c6fb39 spi: Updates for v5.20
The big update this time around is some excellent work from David Jander
 who went through the fast path and really eliminated overheads, meaning
 that we are seeing a huge reduction in the time spent between transfers
 for single threaded clients. Benchmarking has been coming out at about a
 halving of overhead which is clearly visible in system level usage that
 stresses SPI like some CAN and IIO applications, especially with small
 transfers. Thanks to David for taking the time to drill down into this
 and push the work upstream.
 
 Otherwise there's been a bunch of new device support and the usual
 
  - Optimisation of the fast path, particularly around the number and
    types of locking operations, from David Jander.
  - Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
    MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
    Samsung Exynos Auto v9 and 4210.
