[PATCH RESEND 0/2] CFA10036: Switch to SPI Bitbanging

Here is a patchset that moves the spi bus we use to bitbanging. This is needed
because the DAC found on this bus is actually using a 12 bits wordlength, while
the imx28 spi controler can only handle 4, 8 or 16 bits per words.


Maxime Ripard (2):
  spi: spi-gpio: Add checks for the dt properties
  ARM: dts: cfa10049: Change the SPI3 bus to spi-gpio
