Hey folks,

This patchset introduces clock driver support for Exynos 2200.

It's modelled to take advantage of hwacg (hardware auto-clock gating).
This means gates are not defined, so that hwacg takes care of the
gating, which leads to a smaller and simpler clock driver design.

Gate register definitions are left so that they're documented and
in case a gate needs to be forcefully left open in the future, we
won't have to define the register.

Bindings have been tested appropriately:
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j4 dt_binding_check DT_SCHEMA_FILES="Documentation/devicetree/bindings/clock/samsung,exynos2200-cmu.yaml"
  SCHEMA  Documentation/devicetree/bindings/processed-schema.json
Documentation/devicetree/bindings/iio/light/brcm,apds9160.yaml: ps-cancellation-current-picoamp: missing type definition
  CHKDT   ./Documentation/devicetree/bindings
  LINT    ./Documentation/devicetree/bindings
  DTEX    Documentation/devicetree/bindings/clock/samsung,exynos2200-cmu.example.dts
  DTC [C] Documentation/devicetree/bindings/clock/samsung,exynos2200-cmu.example.dtb

Best regards,
Ivaylo

Changes in v2:
 - unify binding and header name with compatible
