From 2ae9f47ce114680dbbc2c56b00ed85eade4f6328 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 11 Jan 2017 16:43:32 +0200 Subject: serial: sh-sci: Fix register offsets for the IRDA serial port [ Upstream commit a752ba18af8285e3eeda572f40dddaebff0c3621 ] Even though most of its registers are 8-bit wide, the IRDA has two 16-bit registers that make it a 16-bit peripheral and not a 8-bit peripheral with addresses shifted by one. Fix the registers offset in the driver and the platform data regshift value.
