From 6150f3bc0b4f94f0eea3e32b4e7462025e4bd972 Mon Sep 17 00:00:00 2001 From: Nicolas Royer Date: Wed, 20 Feb 2013 17:10:23 +0100 Subject: ARM: AT91SAM9G45: same platform data structure for all crypto peripherals MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Only AES use DMA in AT91SAM9G45 (TDES and SHA use PDC). However latest Atmel TDES and SHA IP releases use DMA instead of PDC. --> Atmel TDES and SHA drivers need DMA platform data for those IP releases. Goal of this patch is to use the same platform data structure for all Atmel crypto peripherals. This structure contains information about DMA interface.
