From 4d5a12493518041f6fa66be40e7123dc90c004cd Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Wed, 31 Jan 2018 08:56:38 +0200 Subject: [PATCH] arm64: dts: marvell: mcbin: enable uart headers Add description of the J25 and J27 UART headers of the Macchiatobin. They use uart peripherals that the CP0 (J25) and CP1 (J27) provide. Even though J25 and J27 are labeled as UART header, the pins on these headers can be muxed for other purposes. But the UART functionality is useful when the board is mounted in an ATX style enclosure, since the console UART is not accessible through the microUSB at CON9.
