[PATCH 0/3] SPI Fixes for spi-rockchip

[Doug Anderson]

These three patches are random SPI fixes for spi-rockchip.  They are
unrelated and can be applied / NAKed separately.  They've been tested
in PIO mode on an rk3288 board (since SPI DMA isn't currently working
for some unknown reason).


Doug Anderson (3):
  spi/rockchip: Fix the wait_for_idle() timeout
  spi/rockchip: Don't warn if SPI is busy but disabled
  dt-bindings: spi/rockchip: Mark DMA as optional

[PATCH 3/3] dt-bindings: spi/rockchip: Mark DMA as optional

[Doug Anderson]

The Rockchip SPI controller works fine without DMA (aside from a few
warnings).  The DMA property even implies this, saying:

  DMA request names should include "tx" and "rx" if present.

Officially mark the properties as optional.

Applied all, thanks.  Please use subject bindings matching the style for
the subsystem.
