From ec9b59162fd8317933e362f347a7ed6da7d85618 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Wed, 21 Jun 2017 16:42:12 +0200 Subject: [PATCH] ARM: dts: meson6: use stable UART bindings 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.
