Subject: [PATCH v8 06/18] dmaengine: Add helper function to convert direction value to text
Date: Mon, 23 Dec 2019 13:04:46 +0200 [thread overview]
Message-ID: <20191223110458.30766-7-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20191223110458.30766-1-peter.ujfalusi@ti.com>
dmaengine_get_direction_text() can be useful when the direction is printed
out. The text is easier to comprehend than the number.
