Subject: [PATCH 3/3] ARM: dts: i.MX51: Separate TXD/RXD and RTS/CTS pinmux entries for UARTs
Date: Wed, 14 Aug 2013 13:05:53 +0400 [thread overview]
Message-ID: <1376471153-3452-3-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1376471153-3452-1-git-send-email-shc_work@mail.ru>
RTS/CTS pins can be used for different purposes, so create separate
definitions for these pins.
