Thanks Arnd, Mark, Jamie, Rob, for your review.
Changes in v4:
- add depends on HAVE_CLK && OF && REGULATOR
- add set_cpu_freq fail check
- regulator_put wehn module exit
- add pr_fmt and convert all printk to pr_xxx
- use voltage range
- comment and doc fix
- add cpu_volts value pre-check in module init
- add helpfull module parameter max_freq
- remove compatible string check on Arnd's comment.
- remove generic-cpufreq to clk-reg-cpufreq
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.
