Subject: [PATCH 0/4] spi: A better solution for cros_ec_spi reliability

This series is a much better solution for getting the Chrome OS EC to
talk reliably and replaces commit 37a186225a0c ("platform/chrome:
cros_ec_spi: Transfer messages at high priority").

Note that the cros_ec bits can't land until the SPI bits are
somewhere.  If the SPI bits look OK to land it might be convenient if
they could be placed somewhere with a stable git hash?

Special thanks to Guenter Roeck for pointing out the "realtime"
feature of the SPI framework so I didn't re-invent the wheel.  I have
no idea how I missed it.  :-/

Douglas Anderson (4):
  spi: For controllers that need realtime always use the pump thread
  spi: Allow SPI devices to specify that they are timing sensitive
  platform/chrome: cros_ec_spi: Set ourselves as timing sensitive
  Revert "platform/chrome: cros_ec_spi: Transfer messages at high
    priority"
