From ff2b47f6a9cc10251cc601d34241ee02933c2187 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 22 Oct 2014 16:47:42 +0800 Subject: ARM: sunxi: Add support for uart0 on port F (mmc0) Allwinner SoCs provide uart0 muxed with mmc0, which can then be used with a micro SD breakout board. On the A23, this is the only way to use uart0.
