Subject: [PATCH 2/5] net: fec_imx: Specify that DMA is 32-bit only
Date: Thu, 30 Aug 2018 22:18:23 -0700	[thread overview]
Message-ID: <20180831051826.13587-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180831051826.13587-1-andrew.smirnov@gmail.com>

FEC can only do a DMA transfer to 32-bit address space, so mark it as
such.
