ARM: SA11x0: update clock source registration (2c760b5b) · Commits · 戴 / test

In (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. Signed-off-by:
