Krzysztof Kozlowski 30e1f7bb96 dt-bindings: samsung: document preferred compatible naming
Compatibles can come in two formats.  Either "vendor,ip-soc" or
"vendor,soc-ip".  Add a DT schema documenting preferred policy and
enforcing it for all new compatibles, except few existing patterns.  The
schema also disallows wild-cards used in SoC compatibles.

Guidelines for new compatibles for SoC blocks/components.
When adding new compatibles in new bindings, use the format::
samsung,SoC-IP
For example::
samsung,exynos5433-cmu-isp
select:
properties:
compatible:
pattern: "^samsung,.*(s3c|s5pv|exynos)[0-9a-z]+.*$"
required:
- compatible

# Legacy compatibles with wild-cards - list cannot grow with new bindings:
- enum:
- samsung,exynos4x12-pinctrl
- samsung,exynos4x12-usb2-phy
- samsung,s3c64xx-pinctrl
- samsung,s3c64xx-wakeup-eint
