Subject: [PATCH] ARM: dts: rockchip: enable DMA on SPI for rk3066 and rk3188
Date: Fri, 10 Oct 2014 10:04:13 +0200	[thread overview]
Message-ID: <1412928253-5119-1-git-send-email-julien.chauveau@neo-technologies.fr> (raw)

According to the RK3066 and RK3188 TRM, the two SPI controllers support DMA
handshake interface. Add the DMA properties so they can be used when needed.
