Merge tag 'devfreq-next-for-5.14' of git://git./linux/kernel/git/chanwoo/linux

Pull devfreq material for v5.14 from Chanwoo Choi:

 1. Update devfreq core

  - Use DEVICE_ATTR_RW macro for devfreq userspace governor.

  - Add missing error code in devfreq_add_device().

  - Fix get_target_freq() when not using required-opp.

2. Update devfreq drivers

  - Remove unneeded get_dev_status() and polling_ms from imx-bus.c,
    because imx-bus.c doesn't support simple_ondemand.

  - Remove unneeded DEVFREQ_GOV_SIMPLE_ONDEMAND dependecy from
    imx8m-ddrc.c, because it doesn't support the simple_ondemand
    governor.

  - Use tegra30-devfreq.c as thermal cooling device.

  - Convert dt-binding doc style to yaml and add cooling-cells
    property information to dt-binding doc for tegra30-devfreq.c.
