Subject: [PATCH AUTOSEL for 3.18 10/15] serial: sh-sci: Fix register offsets for the IRDA serial port
Date: Wed, 25 Oct 2017 01:56:29 +0000	[thread overview]
Message-ID: <20171025015622.24698-10-alexander.levin@verizon.com> (raw)
In-Reply-To: <20171025015622.24698-1-alexander.levin@verizon.com>

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

[ 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.
