Subject: ARM: PXA: update clock source registration
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f62ae0ce4369effc432ea25df09c88d7aa08965e;p=mv-sheeva.git

ARM: PXA: update clock source registration

In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.
