From 41147bfdc5c0d6acb39d2b3b8a4eb6ffb08e4b42 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Tue, 1 Jan 2013 00:21:55 -0800 Subject: [PATCH] serial: samsung: remove the use of statically remapped controller address The address S3C_VA_UART is a statically ioremapped address. The driver should not be using this. Instead, the driver should setup a mapping during probe.
