From f62ce2a12e69b30c4ac6d533b6eef247916bf968 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 28 Dec 2017 15:51:39 +0100 Subject: imx8: support UART1 as console UART for Apalis iMX8 Make sure we return the clock of UART1 when building for Apalis iMX8. NXP LPUART1 is used as Apalis UART1, which is typically the main console on our Linux BSP.
