The driver support single core and multi core ARM SoCs. For multi core, it assume all cores share the same clock and voltage.
TODO: - Add each core seperate freq/volt support (MSM).
Changes in v3: - move adjusting smp loops_per_jiffy to arm common code, and also adjust global loops_per_jiffy. - remove adjusting loops_per_jiffy in imx and omap cpufreq drivers. - check compatible "generic-cpufreq" when module_init - change printk to pr_xxx - add generic-cpufreq DT binding doc
Changes in v2: - add volatage change support - change '_' in property name to '-' - use initial value to calculate loops_per_jiffy - fix reading cpu_volts property bug - let cpufreq_frequency_table_cpuinfo routines handle cpu_freq_khz_max/min - don't change freq in arm_cpufreq_exit, because every core share the same freq. - use unsigned long describe frequency as much as possible. Because clk use unsigned long, but cpufreq use unsigned int.
