Subject: [PATCH 1/3] ARM: dts: i.MX51: Separate TXD/RXD and RTS/CTS pinmux entries for UARTs
Date: Wed, 21 Aug 2013 11:28:23 +0400 [thread overview]
Message-ID: <1377070105-15902-1-git-send-email-shc_work@mail.ru> (raw)
RTS/CTS pins can be used for different purposes, so create separate
definitions for these pins.
Signed-off-by: Alexander Shiyan <shc_work@mail.ru>
