From 80e061467008a7d6e8670c2630b5be6b428d00cb Mon Sep 17 00:00:00 2001 From: Thomas Chou <thomas@wytron.com.tw> Date: Sun, 29 Nov 2015 14:01:03 +0800 Subject: [PATCH] ns16550: change reg-shift property default to zero Change reg-shift property default to zero. When the integer property is missing, it should be taken as zero. This is consistent to Linux drivers/tty/serial/of_serial.c. The x86 and most powerpc use reg-shift of 0. Most others use reg-shift of 2. While reg-shift of 1 is rarely used.
