[PATCH V6 4/7] cpufreq: add clk-reg cpufreq driver

The driver get cpu operation point table from device tree cpu0 node, and adjusts operating points using clk and regulator APIs. It support single core and multi-core ARM SoCs. But currently it assume all cores share the same frequency and voltage. Signed-off-by: Richard Zhao Reviewed-by: Jamie I

[PATCH V6 1/7] ARM: add cpufreq transiton notifier to adjust loops_per_jiffy for smp

If CONFIG_SMP, cpufreq skips loops_per_jiffy update, because different arch has different per-cpu loops_per_jiffy definition. Signed-off-by: Richard Zhao --- arch/arm/kernel/smp.c | 54 + 1 files changed, 54 insertions(+), 0 deletions(-) diff --

[PATCH V6 0/7] add a generic cpufreq driver

The driver is based on clock and regulator APIs and support single core and multi core ARM SoCs. For multi core, it assume all cores share the same clock and voltage. Thanks Arnd, Mark, Jamie, Shawn, Rob, for your review. Changes in V6: - add scaling_available_freqs Changes in V5: - add more
