Subject: [PATCH 09/37] atl1c: correct wrong definition of REG_DMA_CTRL
Date: Fri, 13 Apr 2012 08:14:34 +0800 [thread overview]
Message-ID: <1334276102-15866-10-git-send-email-xiong@qca.qualcomm.com> (raw)
In-Reply-To: <1334276102-15866-1-git-send-email-xiong@qca.qualcomm.com>
some fields of REG_DMA_CTRL(15C0) are wrong, replace with the newest one.
haredware uses fixed dma-write-block size, remove dmaw_block related code
in function atl1c_configure_dma.
