Merge tag 'devfreq-next-for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq updates for 5.17-rc1 from Chanwoo Choi:

"1. Add new DRAM controller driver for sunXi SoCs

    - Add DRAM frequency controller devfreq driver for Allwinner sunXi SoCs
      in order to support dynamic frequency scaling of DRAM frequency.

      It calculates the supported frequency list from source clock in the
      range of full speed to quarter speed instead of devicetree.

    - Add COMMON_CLK dependency to fix build error

 2. Reduce log severity for informative message about frequency transition
    failures"
