Merge tag 'spi-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "This has been a fairly quiet release for SPI, though it is likely that
  the next release will have some big changes as there's some
  preparatory work for multiple chip select support gone in - the rest
  of the code is on the list but will need to be rebased onto -rc1.
  Otherwise there's a couple of new tunables for chip select timings,
  some new devices and smaller device specific updates and fixes.

   - Support for configuring the hold and minimum inactive times for
     chip selects.

   - Beginnings of support for supporting devices which have multiple
     chip selects on a single device.

   - Support for newer Broadcom HSSPI and Intel controllers, Silicon
     Labs EM3581 and SI3210"
