[0/3] inter-word delays for spidev and spi-orion

Message

This builds on recent work by Jonas Bonn who added a generic way of
inserting interword delays into SPI transfers. I need that on a slave
connected to spi-orion and accessed via spidev, hence this patch series.

I also took the liberty to clean up the spi-orion from my previous, and
now obsolete, effort at moving per-child options into an extra struct.

Jan Kundrát (3):
  spi: spidev: Enable control of inter-word delays
  spi: orion: Support spi_xfer->word_delay_usecs
  Revert "spi: orion: Prepare space for per-child options"
