PM / devfreq: Move exynos4 devfreq driver into a new sub-directory

2013-06-03T11:20:29Z

In anticipation of the new exynos5 devfreq and ppmu driver, create an exynos sub-directory. Move the existing exynos4 devfreq driver into the same. Signed-off-by: Abhilash Kesavan Acked-by: MyungJoo Ham Cc: Jonghwan Choi Cc: Kukjin Kim

Conflicts: drivers/devfreq/exynos4_bus.c Sync with Linus' tree to be able to apply patches that are against newer code (mvneta).

PM / devfreq: exynos4_bus: honor RCU lock usage

2013-01-22T12:28:40Z

OPP pointers cannot be expected to be valid beyond the boundary of rcu_read_lock and rcu_read_unlock. Unfortunately, the current exynos4 busfreq driver does not honor the usage constraint and stores the OPP pointer in struct busfreq_data. This could potentially become invalid later such as: across devfreq opp change decisions, resulting in unpredictable behavior. To fix this, we introduce a busfreq specific busfreq_opp_info structure which is used to handle OPP information. OPP information is de-referenced to voltage and frequency pairs as needed into busfreq_opp_info structure and used as needed. Signed-off-by: Nishanth Menon Signed-off-by: Rafael J. Wysocki

Drivers: misc: remove __dev* attributes.

2013-01-03T23:57:16Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Signed-off-by: Greg Kroah-Hartman

PM / devfreq: map devfreq drivers to governor using name

2012-11-20T09:46:22Z

Allow devfreq drivers to register a preferred governor name and when the devfreq governor loads itself at a later point required drivers are managed appropriately, at the time of unload of a devfreq governor, stop managing those drivers as well. Since the governor structures do not need to be exposed anymore, remove the definitions and make them static NOTE: devfreq_list_lock is now used to protect governor start and stop - as this allows us to protect governors and devfreq with the proper dependencies as needed. As part of this change, change the registration of exynos bus driver to request for ondemand using the governor name. Cc: Rajagopal Venkat Cc: MyungJoo Ham Cc: Kyungmin Park Cc: "Rafael J.

PM / devfreq: Use devm_* functions in exynos4_bus.c

2012-11-20T06:59:22Z

devm_* functions are device managed functions and make cleanup code simpler and smaller. devm_kzalloc and devm_regulator_get functions are used. Signed-off-by: Sachin Kamat [renamed the patch title by MyungJoo Ham] Signed-off-by: MyungJoo Ham

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
