PM / devfreq: event: use devm_platform_get_and_ioremap_resource()

2022-12-05T12:57:20Z

Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does. Signed-off-by: Minghao Chi Signed-off-by: ye xingchen Signed-off-by: Chanwoo Choi

PM/devfreq: governor: Add a private governor_data for governor

2022-11-20T11:49:51Z

The member void *data in the structure devfreq can be overwrite by governor_userspace. For example: 1. The device driver assigned the devfreq governor to simple_ondemand by the function devfreq_add_device() and init the devfreq member void *data to a pointer of a static structure devfreq_simple_ondemand_data by the function devfreq_add_device(). 2. The user changed the devfreq governor to userspace by the command "echo userspace > /sys/class/devfreq/.../governor". 3. The governor userspace alloced a dynamic memory for the struct userspace_data and assigend the member void *data of devfreq to this memory by the function userspace_init(). 4. The user changed the devfreq governor back to simple_ondemand by the command "echo simple_ondemand > /sys/class/devfreq/.../governor". 5. The governor userspace exited and assigned the member void *data in the structure devfreq to NULL by the function userspace_exit(). 6. The governor simple_ondemand fetched the static information of devfreq_simple_ondemand_data in the function devfreq_simple_ondemand_func() but the member void *data of devfreq was assigned to NULL by the function userspace_exit(). 7. The information of upthreshold and downdifferential is lost and the governor simple_ondemand can't work correctly. The member void *data in the structure devfreq is designed for a static pointer used in a governor and inited by the function devfreq_add_device(). This patch add an element named governor_data in the devfreq structure which can be used by a governor(E.g userspace) who want to assign a private data to do some private things.

PM / devfreq: rockchip-dfi: Fix an error message

2022-09-25T18:59:43Z

There is a typo in the message. The clock name should be 'pclk_ddr_mon'. Fix it. While at it, switch to dev_err_probe() which is less verbose, filters -EPROBE_DEFER, and log the error code in a human readable way. Signed-off-by: Christophe JAILLET Signed-off-by: Chanwoo Choi

PM / devfreq: mtk-cci: Handle sram regulator probe deferral

2022-09-25T18:59:12Z

If the regulator_get_optional() call for the SRAM regulator returns a probe deferral, we must bail out and retry probing later: failing to do this will produce unstabilities on platforms requiring the handling for this regulator.
