Subject: ARM: sun5i: dt: enable DMA on SPI
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fed4c5c676f41359c7dbee635bd98e25e54c40f4;p=linux-beck.git

ARM: sun5i: dt: enable DMA on SPI

All of our SPI controllers support DMA transfers, so let's add the
properties here so they can be used when it's best to do so.
