From mboxrd@z Thu Jan 1 00:00:00 1970 From: nicolas.ferre@atmel.com (Nicolas Ferre) Date: Thu, 1 Dec 2016 11:49:47 +0100 Subject: [PATCH 1/3] ARM: dts: at91: add dma1 definition to sama5d2 Message-ID: <20161201104949.23985-1-nicolas.ferre@atmel.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The sama5d2 SoC has a second DMA controller and can be used just like DMA0. By default both DMA controllers are configured as "Secure" in MATRIX_SPSELR so we can use whichever we want in a "single Secure World" configuration. Surprisingly the DMA1 has a lower address than DMA0. To avoid confusion place it after DMA0 node anyway.
