Subject: [PATCH 04/12] mci: imx-esdhc-pbl: Don't setup DMA registers
Date: Mon,  2 Dec 2019 07:19:46 -0800	[thread overview]
Message-ID: <20191202151954.16032-5-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20191202151954.16032-1-andrew.smirnov@gmail.com>

PBL code is PIO only, so setting up DMA related registers shouldn't be
necessary.
