Subject: [RFC PATCH 06/11] dma: amba-pl08x: Keep LLIs aligned to 4-word boundary
Date: Sun, 16 Jun 2013 22:54:13 +0200

PL080 reference manual states that to LLI entries should be aligned
to 4-word boundary to make LLI fetches more efficient. This patch adds
a 3-word padding to the LLi struct to make this condition true.
