Subject: [PATCH 06/10] ARM: dts: mmp*: Make the serial ports compatible with xscale-uart
Date:   Fri, 20 Mar 2020 18:41:03 +0100
Message-Id: <20200320174107.29406-7-lkundrak@v3.sk>
In-Reply-To: <20200320174107.29406-1-lkundrak@v3.sk>
References: <20200320174107.29406-1-lkundrak@v3.sk>

Precedence: bulk

XScale serial port driver is perfectly capable of supporting this hardware. A
separate compatible string is probably a historical mess.
