Subject: [PATCH] arm: dts: logicpd-torpedo: Add isp1763 support to baseboard
Date:   Thu, 10 Feb 2022 07:10:28 -0600
Message-Id: <20220210131028.1404851-1-aford173@gmail.com>
MIME-Version: 1.0

Precedence: bulk

The baseboard has an ISP1763 USB controller acting as a host.
Since the pinmuxing for the corresponding IRQ is different
between OMAP35 and DM37, the pinmux has been placed in the
kit-level files, while the common code is placed into the
baseboard file.
