Subject: [PATCH V2 0/4] add arm soc generic cpufreq driver
Date: Fri, 16 Dec 2011 18:30:58 +0800 [thread overview]
Message-ID: <1324031462-24961-1-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.
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.
[PATCH V2 1/4] cpufreq: add arm soc generic cpufreq driver
[PATCH V2 2/4] dts/imx6q: add cpufreq property
[PATCH V2 3/4] arm/imx6q: register arm_clk as cpu to clkdev
[PATCH V2 4/4] arm/imx6q: select ARCH_HAS_CPUFREQ
Thanks
Richard
