Subject: [PATCH v2 1/2] m33xx-clock: configure PLLs based on oscillator frequency
Date: Thu, 18 Apr 2013 11:47:09 +0200 [thread overview]
Message-ID: <1366278430-4009-1-git-send-email-jlu@pengutronix.de> (raw)
The *PLL_N values can be calculated from the OSC value. This patch
includes no functional change.
Signed-off-by: Jan Luebbe <jlu@pengutronix.de>

changes from v1:
* add change description (sha)
* add spaces around operator (sha)
* split off patch to remove unused code
