Merge tag 'spi-v5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

dcc75dde · Linus Torvalds <[email protected]> · 2019-03-04 19:23:56 -08:00

Pull spi updates from Mark Brown:
 "A fairly quiet release for SPI, the biggest thing is the conversion to
  use GPIO descriptors which is now 90% done but still needs some
  stragglers converting.

  Summary:

   - Support for inter-word delays

   - Conversion of the core and most drivers to use GPIO descriptors for
     GPIO controlled chip selects

   - New drivers for NXP FlexSPI and QuadSPI, SiFive and Spreadtrum"
