| Subject | [PATCH v5 4/4] ARM: dts: meson6: use stable UART bindings |
| Date | 2017-06-14 10:40 +0200 |

The UART bindings needs specifying a SoC family, use the meson6 family
for the UART nodes like the other nodes.
Switch to the stable UART bindings for meson6 by adding a XTAL node and
using the proper compatible strings.
