PM: devfreq: init performance/powersave governor

2012-05-01T19:23:50Z

Performance and powersave governor's get_target_freq is not called if driver chooses one of these two governors. Add init function in governor profile to call update_devfreq which will call get_target_freq subsequently. Signed-off-by: Xiaoguang Chen Acked-by: MyungJoo Ham Signed-off-by: Rafael J. Wysocki

Pull "ARM: global cleanups" from Arnd Bergmann: "Quite a bit of code gets removed, and some stuff moved around, mostly the old samsung s3c24xx stuff. There should be no functional changes in this series otherwise. Some cleanups have dependencies on other arm-soc branches and will be sent in the second round.

PM / devfreq: add relation of recommended frequency.

2012-03-17T20:51:34Z

The semantics of "target frequency" given to devfreq driver from devfreq framework has always been interpretted as "at least" or GLB (greatest lower bound). However, the framework might want the device driver to limit its max frequency (LUB: least upper bound), especially if it is given by thermal framework (it's too hot). Thus, the target fuction should have another parameter to express whether the framework wants GLB or LUB. And, the additional parameter, "u32 flags", does it. With the update, devfreq_recommended_opp() is also updated. Signed-off-by: MyungJoo Ham Signed-off-by: Kyungmin Park Reviewed-by: Mike Turquette Signed-off-by: Rafael J. Wysocki

PM / devfreq: add min/max_freq limit requested by users.

devfreq: Remove MODULE_ALIAS for exynos4 busfreq driver

2012-01-20T01:12:38Z

This driver can only be built-in, it does not make sense to add modalias for it (in addition to being incorrect, the platform modalias needs to be prefixed with "platform:"). Signed-off-by: Axel Lin Signed-off-by: MyungJoo Ham
