Merge tag 'spi-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi updates from Mark Brown:
 "One small feature was added this release but the bulk of the diffstat
  and the changelog comes from the fact that several older drivers got
  some fairly hefty reworks and a couple of new drivers were added:

   - Support for detailed control of timing around chip selects from
     Sowjanya Komatineni.

   - A big set of fixes and imrovements for the Tegra114 driver from
     Sowjanya Komatineni.

   - A big simplification of the GPIO driver from Andrey Smirnov.

   - DMA support and fixes for the Freescale LPSPI driver from Clark
     Wang.

   - Fixes and optimizations for the bcm2835aux from Martin Sparl.

   - New drivers for Mediatek MT7621 (graduated from staging) and Zynq
     QSPI"

[ This is a so-called "evil merge" that additionally removes a warning
  due to an unused variable 'i' introduced by commit 1dfbf334f1 ("spi:
  ep93xx: Convert to use CS GPIO descriptors")     - Linus ]
