devfreq: use HZ macros

2021-09-08T18:50:26Z

HZ unit conversion macros are available in units.h, use them and remove the duplicate definition. The new macro has an unsigned long type. All the code is dealing with unsigned long and the code using the macro is doing a coercitive cast to unsigned long.

PM / devfreq: passive: Fix get_target_freq when not using required-opp

2021-06-24T01:37:35Z

The 86ad9a24f21e ("PM / devfreq: Add required OPPs support to passive governor") supported the required-opp property for using devfreq passive governor. But, 86ad9a24f21e has caused the problem on use-case when required-opp is not used such as exynos-bus.c devfreq driver. So that fix the get_target_freq of passive governor for supporting the case of when required-opp is not used.

PM / devfreq: userspace: Use DEVICE_ATTR_RW macro

2021-06-17T08:08:46Z

Use DEVICE_ATTR_RW helper instead of plain DEVICE_ATTR, which makes the code a bit shorter and easier to read. Signed-off-by: YueHaibing Signed-off-by: Chanwoo Choi

PM / devfreq: imx8m-ddrc: Remove DEVFREQ_GOV_SIMPLE_ONDEMAND dependency

2021-05-21T04:16:21Z

The driver can't support simple ondemand governor due to missing .get_dev_status() capability. Signed-off-by: Dong Aisheng Signed-off-by: Chanwoo Choi

PM / devfreq: tegra30: Support thermal cooling

2021-05-21T04:16:10Z

Expose ACTMON devfreq device as a cooling device in order to throttle memory freq on overheat. Throttling of memory freq has a significant cooling effect on NVIDIA Tegra SoCs since higher memory freqs require higher SoC core voltage which is one of the main causes of the heating.

PM / devfreq: imx-bus: Remove imx_bus_get_dev_status

2021-05-21T04:16:10Z

Current driver actually does not support simple ondemand governor as it's unable to provide device load information. So removing the unnecessary callback to avoid confusing. Right now the driver is using userspace governor by default. polling_ms was also dropped as it's not needed for non-ondemand governor. Signed-off-by: Dong Aisheng Signed-off-by: Chanwoo Choi

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

2021-05-20T03:16:41Z

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

PM / devfreq: imx8m-ddrc: Remove unneeded of_match_ptr()

2021-04-08T04:14:51Z

i.MX is a DT-only platform, so of_match_ptr() can be safely removed. Remove the unneeded of_match_ptr(). Signed-off-by: Fabio Estevam Signed-off-by: Chanwoo Choi
