Subject: [PATCH V3 0/7] add a generic cpufreq driver
Date: Mon, 19 Dec 2011 11:21:36 +0800	[thread overview]
Message-ID: <1324264903-15395-1-git-send-email-richard.zhao@linaro.org> (raw)

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.
