From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yoshinori Sato Date: Wed, 11 Jul 2018 11:41:22 +0000 Subject: [PATCH] [RFC] serial: sh-sci: fix register alocation in h8300. Message-Id: <20180711114121.10735-1-ysato@users.sourceforge.jp> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org h8300's SCI registers aligned byte address. Although it may be appropriate to put it in sci_port_params, because I can not think of a good way, I did it like this.
