PM / devfreq: Send the DEVFREQ_POSTCHANGE notification when target() is failed

2016-06-23T21:15:12Z

This patch sends the DEVFREQ_POSTCHANGE notification when devfreq->profile->targer() is failed. The PRECHANGE/POSTCHANGE should be paired.

PM / devfreq: fix initialization of current frequency in last status

2016-06-22T04:53:00Z

Some systems need current frequency from last_status for calculation but it is zeroed during initialization. When the device starts there is no history, but we can assume that the last frequency was the same as the initial frequency (which is also used in 'previous_freq'). The log shows the result of this misinterpreted value. [ 2.042847] ... Failed to get voltage for frequency 0: -34 Signed-off-by: Lukasz Luba Reviewed-by: Javi Merino Signed-off-by: MyungJoo Ham

PM / devfreq: exynos-nocp: Remove incorrect IS_ERR() check

2016-06-22T04:52:55Z

Smatch complains because platform_get_resource() returns NULL on error and not an error pointer so the check is wrong. Julia Lawall pointed out that normally we don't check these, because devm_ioremap_resource() has a check for NULL. Signed-off-by: Dan Carpenter Reviewed-by: Julia Lawall Signed-off-by: MyungJoo Ham

PM / devfreq: remove double put_device

2016-06-22T04:52:52Z

When device_register() returns with error, it has already done put_device() on the input device pointer. Signed-off-by: MyungJoo Ham

PM / devfreq: fix double call put_device

PM / devfreq: fix duplicated kfree on devfreq pointer

2016-06-22T04:52:40Z

device_unregister() calls kfree already. Signed-off-by: MyungJoo Ham

PM / devfreq: devm_kzalloc to have dev pointer more precisely

2016-06-22T04:51:08Z

devm_kzalloc of devfreq's statistics data structure has been using its parent device as the dev allocated for. If a device's devfreq is disabled in run-time, such allocated memory won't be freed. Desginating more precisely with the devfreq device pointer fixes the issue. Signed-off-by: MyungJoo Ham

PM / devfreq: event: Find the instance of devfreq-event device by using phandle

2016-05-03T02:21:51Z

This patch use the phandle to find the instance of devfreq-event device in Device Tree when calling the devfreq_event_get_edev_by_phandle() because there is two type devfreq-event devices as following: First case, exynos-ppmu.c driver provides the maximum four event of each PPMU. So, when getting the instance of devfreq-event device, using the unique name of struct devfreq_event_desc. Second case, exynos-nocp.c driver provide the only one event of each NoC Probe device. So, when getting the instance of devfreq-event device, using the phandle of each NoC probe device. Signed-off-by: Chanwoo Choi Acked-by: MyungJoo Ham

PM / devfreq: event: Add new Exynos NoC probe driver

2016-05-03T02:21:07Z

This patch adds NoC (Network on Chip) Probe driver which provides the primitive values to get the performance data. The packets that the Network on Chip (NoC) probes detects are transported over the network infrastructure. Exynos542x bus has multiple NoC probes to provide bandwidth information about behavior of the SoC that you can use while analyzing system performance.
