Subject: [PATCH 09/21] mci: tegra: Use 16bit register definitions
Date: Tue, 19 Nov 2019 11:50:24 +0100	[thread overview]
Message-ID: <20191119105036.12300-10-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20191119105036.12300-1-s.hauer@pengutronix.de>

We have some register defines in a 16bit access version and a 32bit
access version. Use the former to get rid of the latter later.
