[PATCH 00/17] dt-bindings: samsung: add specific compatibles for existing SoC

[Krzysztof Kozlowski]

Hi,

Merging
=======
I propose to take entire patchset through my tree (Samsung SoC), because:
1. Next cycle two new SoCs will be coming (Google GS101 and ExynosAutov920), so
   they will touch the same lines in some of the DT bindings (not all, though).
   It is reasonable for me to take the bindings for the new SoCs, to have clean
   `make dtbs_check` on the new DTS.
2. Having it together helps me to have clean `make dtbs_check` within my tree
   on the existing DTS.
3. No drivers are affected by this change.
4. I plan to do the same for Tesla FSD and Exynos ARM32 SoCs, thus expect
   follow up patchsets.

If folks agree, please kindly Ack the patches.

Description
===========
Samsung Exynos SoCs reuse several devices from older designs, thus historically
we kept the old (block's) compatible only.  This works fine and there is no bug
here, however guidelines expressed in
Documentation/devicetree/bindings/writing-bindings.rst state that:
1. Compatibles should be specific.
2. We should add new compatibles in case of bugs or features.

Add compatibles specific to each SoC in front of all old-SoC-like compatibles.
This will also help reviews of new code using existing DTS as template.  No
functional impact on Linux drivers behavior.

Future
======
If reasonable, I will do similar work for Tesla FSD and ARMv7/ARM32 Exynos
bindings and DTS.

Best regards,
Krzysztof
