[PATCH v2] ARM64: dts: meson-gxbb-wetek: add ttyAML1 uart for Bluetooth

From: Christian Hewitt
Date: Fri Sep 07 2018 - 08:16:31 EST


This change adds the uart_A used by the brmcfmac sdio module in the
WeTek Hub and WeTek Play 2 devices. meson_uart_probe seems to mandate
an alias (without it, BT is not working) so this is also included.
