PM / devfreq: Add missing error code in devfreq_add_device()

2021-07-14T14:56:11+00:00

[ Upstream commit 18b380ed61f892ed06838d1f1a5124d966292ed3 ] Set err code in the error path before jumping to the end of the function. Fixes: 4dc3bab8687f ("PM / devfreq: Add support delayed timer for polling mode") Signed-off-by: YueHaibing Signed-off-by: Chanwoo Choi Signed-off-by: Sasha Levin

PM / devfreq: Use more accurate returned new_freq as resume_freq

2021-05-14T07:50:15+00:00

[ Upstream commit 62453f1ba5d5def9d58e140a50f3f168f028da38 ] Use the more accurate returned new_freq as resume_freq. It's the same as how devfreq->previous_freq was updated.

PM / devfreq: Unlock mutex and free devfreq struct in error path

2021-05-14T07:49:58+00:00

commit 8b50a7995770d41a2e8d9c422cd2882aca0dedd2 upstream. The devfreq->lock is held for time of setup. Release the lock in the error path, before jumping to the end of the function. Change the goto destination which frees the allocated memory.

PM / devfreq: tegra30: Improve initial hardware resetting

2020-09-29T08:50:10+00:00

It's safe to enable the ACTMON clock at any time during driver probing, even if we don't know the state of hardware, because it's used only for collecting and processing stats, and interrupt is kept disabled. This allows us to slightly improve code which performs initial hardware resetting by making use of a single reset_control_reset() instead of assert/deassert pair. Secondly, a potential error of the reset-control API is handled nicely now. Signed-off-by: Dmitry Osipenko Signed-off-by: Chanwoo Choi

PM / devfreq: event: Change prototype of devfreq_event_get_edev_by_phandle function

2020-09-29T08:50:10+00:00

Previously, devfreq core support 'devfreq-events' property in order to get the devfreq-event device by phandle. But, 'devfreq-events' property name is not proper on devicetree binding because this name doesn't mean the any h/w attribute. The devfreq-event core hand over the rights to decide the property name for getting the devfreq-event device on devicetree. Each devfreq-event driver will decide the property name on devicetree binding and then pass the their own property name to devfreq_event_get_edev_by_phandle function. And change the prototype of devfreq_event_get_edev_count function because of used deprecated 'devfreq-events' property. Acked-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi

PM / devfreq: Add devfreq_get_devfreq_by_node function

2020-09-29T08:50:09+00:00

Split off part of devfreq_get_devfreq_by_phandle into a separate function. This allows callers to fetch devfreq instances by enumerating devicetree instead of explicit phandles.

PM / devfreq: tegra30: Disable clock on error in probe

PM / devfreq: Add timer type to devfreq_summary debugfs

2020-09-23T04:35:58+00:00

The commit 4dc3bab8687f ("PM / devfreq: Add support delayed timer for polling mode") supports the delayed timer but this commit missed the adding the timer type to devfreq_summary debugfs node.
