From 5fcea8d3f9efe9db0196fba98cf0c5fc7afb942b Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Wed, 25 Sep 2019 17:45:20 +0800 Subject: [PATCH] dts: mtmips: enable high-speed UART support for mt7628 All three UARTs of mt7628 are actually MediaTek's high-speed UARTs which support baudrate up to 921600. The high-speed UART is compatible with ns16550 when baudrate <= 115200. Add compatible string to dtsi file so u-boot can use it when serial_mtk driver is built in.
