Subject: [PATCH v4 07/10] dma: ti: k3-udma: Switch to exposed ring mode
Date: Mon, 9 Dec 2019 10:25:37 +0530 [thread overview]
Message-ID: <20191209045540.10702-8-vigneshr@ti.com> (raw)
In-Reply-To: <20191209045540.10702-1-vigneshr@ti.com>
Exposed ring mode works well with 32 bit and 64 bit cores without need
for Proxies for 32 bit cores. Therefore switch to exposed ring mode.
