Merge tag 'spi-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This release is almost entirely new drivers, with a couple of small
  changes in generic code.

  The biggest individual update is a rename of the existing Microchip
  driver and the addition of a new driver for the silicon SPI controller
  in their PolarFire SoCs. The overlap between the soft IP supported by
  the current driver and this new one is regrettably all in the IP and
  not in the register interface offered to software.

   - Add a time offset parameter for offloads, allowing them to be
     defined in relation to each other. This is useful for IIO type
     applcations where you trigger an operation then read the result
     after a delay.

   - Add a tracepoint for flash exec_ops, bringing the flash support
     more in line with the debuggability of vanilla SPI.

   - Support for Airoha EN7523, Arduino MCUs, Aspeed AST2700, Microchip
     PolarFire SPI controllers, NXP i.MX51 ECSPI target mode, Qualcomm
     IPQ5414 and IPQ5332, Renesas RZ/T2H, RZ/V2N and RZ/2NH and SpacemiT
     K1 QuadSPI.

  There's also a small set of ASoC cleanups that I mistakenly applied to
  the SPI tree and then put more stuff on top of before it was brought
  to my attention, sorry about that"
