Subject: [PATCH v2 14/24] serial: mpc512x: setup the PSC FIFO clock as well
Date: Thu, 18 Jul 2013 19:00:45 +0200 [thread overview]
Message-ID: <1374166855-7280-15-git-send-email-gsi@denx.de> (raw)
In-Reply-To: <1374166855-7280-1-git-send-email-gsi@denx.de>
prepare and enable the FIFO clock upon PSC FIFO initialization,
disable and unprepare the FIFO clock upon PSC FIFO uninitialization,
remove the pre-enable workaround from the platform's clock driver
Signed-off-by: Gerhard Sittig <gsi@denx.de>
