[0/5] MediaTek Helio X10 MT6795 - Clock drivers

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This (very big) series introduces system clock, multimedia clock drivers
(including resets) for this SoC.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/arm/mediatek/mediatek,mt6795-clock.yaml:67:1: [warning] too many blank lines (2 > 1) (empty-lines)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
