Subject: [PATCH 2/2] USB: at91: using USBA_NR_DMAS for DMA channels
Date: Fri, 17 Jan 2014 10:59:25 +0800	[thread overview]
Message-ID: <1389927565-22477-2-git-send-email-voice.shen@atmel.com> (raw)
In-Reply-To: <1389927565-22477-1-git-send-email-voice.shen@atmel.com>

When the SoC is earlier than sama5d3 SoC, which have the same number
endpoints and DMAs. However for sama5d3 SoC, it has different number
for endpoints and DMAs. So, define USBA_NR_DMAs for DMA channels
