Subject: [PATCH v3 06/18] i.MX: serial: Convert i.MX51 and i.MX6 to use 'imx*_uart_setup_ll'
Date: Wed,  6 May 2015 12:32:01 -0700	[thread overview]
Message-ID: <1430940733-4415-7-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1430940733-4415-1-git-send-email-andrew.smirnov@gmail.com>

NOTE: Boards 'karo-tx25' and 'tqma53' can benefit from this
refactoring as well, but they were not converted because of the lack
of i.MX25 or i.MX53 based hardware to test on.
