Subject: [PATCH 05/16] ARM: dts: lpc18xx: add dma to ssp0/1
Date: Thu, 1 Oct 2015 22:54:42 +0200 [thread overview]
Message-ID: <1443732893-17145-6-git-send-email-manabian@gmail.com> (raw)
In-Reply-To: <1443732893-17145-1-git-send-email-manabian-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
Add dmas entries to the two SSP peripherals on LPC18xx/43xx devices
so that DMA can be used to transfer data.
