From d3544a20a849582542f5a89eac4b6874d3e37c1b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 29 Jun 2015 06:48:41 +0000 Subject: [PATCH] bcm53xx: rework patch enabling UART support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow upstream patch and handle it using &uart0. Also disable &uart1 as it's most likely unused. This will allow us to get valuable reports and upstream these changes.
