Subject: [PATCH 02/13] serial: sh-sci: Add (H)SCIF RTS/CTS pin data register bit definitions
Date: Thu, 30 Apr 2015 18:21:26 +0200 [thread overview]
Message-ID: <1430410897-12770-3-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1430410897-12770-1-git-send-email-geert+renesas@glider.be>
Add the missing register bit definitions to set the RTS pin and read the
CTS pin on (H)SCIF.
Extracted from patches by Magnus Damm <damm+renesas@opensource.se>.
