PM / devfreq: tegra30: Add error message for devm_devfreq_add_device() (2022-07-15 11:40:08 +0900)
----------------------------------------------------------------

Update devfreq next for v5.20

Detailed description for this pull request:
1. Add new Mediatek CCI (Cache Coherent Interconnect) devfreq driver
- Add new MediaTek Cache Coherent Interconnect (CCI) devfreq drviver
which supports the dynamic voltage and clock scaling.
This driver uses the passive devfreq governor to get target frequencies
and adjust voltages because it depends on MediaTek cpu frequency
driver. In MT8183 and MT8186, the MediaTek CCI is supplied
by the same regulators with the little core CPUs.

2. Update the devfreq drivers
- Convert the Samsung Exynos SoC Bus bindings to DT schema of exynos-bus.c

- Remove kernel-doc warnings by adding the description for unused
fucntio parameters on devfreq core.

- Use NULL to pass a null pointer rather than zero according to function
propotype on imx-bus.c

- Print error message instead of error interger value on tegra30-devfreq.c
