Subject: [PATCH 37/41] drivers: tty: serial: 8250: simplify io resource size computation
Date: Sat, 27 Apr 2019 14:52:18 +0200 [thread overview]
Message-ID: <1556369542-13247-38-git-send-email-info@metux.net> (raw)
In-Reply-To: <1556369542-13247-1-git-send-email-info@metux.net>
Simpily io resource size computation by setting mapsize field.
Some of the special cases handled by serial8250_port_size() can be
simplified by putting this data to corresponding platform data
or probe function.
