Subject: [PATCH v1 14/24] powerpc/mpc512x: improve DIU related clock setup
Date: Mon, 15 Jul 2013 20:47:43 +0200 [thread overview]
Message-ID: <1373914074-20889-15-git-send-email-gsi@denx.de> (raw)
In-Reply-To: <1373914074-20889-1-git-send-email-gsi@denx.de>
adapt the DIU clock initialization to the COMMON_CLK approach: device
tree based clock lookup, prepare and unprepare for clocks, work with
frequencies not dividers, call the appropriate clk_*() routines and
don't access CCM registers, remove the pre-enable workaround in the
platform's clock driver
the "best clock" determination now completely relies on the platform's
clock driver to pick a frequency close to what the caller requests, and
merely checks whether the desired frequency was met (is acceptable since
it meets the tolerance of the monitor) -- this approach shall succeed
upon first try in the usual case, will test a few less desirable yet
acceptable frequencies in edge cases, and will fallback to "best effort"
if none of the previously tried frequencies pass the test
