Subject: [PATCH v2 2/7] dmaengine: mcf-edma: update to 'dmamux_nr'
Date: Mon, 27 May 2019 16:51:13 +0800 [thread overview]
Message-ID: <20190527085118.40423-3-yibin.gong@nxp.com> (raw)
In-Reply-To: <20190527085118.40423-1-yibin.gong@nxp.com>
From: Robin Gong <yibin.gong@nxp.com>
Update to 'dmamux_nr' instead of static macro DMAMUX_NR since
new version edma only has one dmamux.
Signed-off-by: Robin Gong <yibin.gong@nxp.com>
