From 9e83bbdb6fc3414a46ce92ceafa53f0067bc1f57 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 30 Aug 2017 12:16:06 +0200 Subject: arm64: dts: marvell: add UART muxing on Armada 7K/8K This commit adds the relevant details in the Armada 7K/8K Device Tree to properly mux the UART used for the serial console. Since there is basically only one possible muxing for the UART0 on the AP, the muxing configuration is described in armada-ap806.dtsi, and selected from the individual boards (other boards could be using a different UART).
