[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

Re-shuffle also the entries in compatibles, so the one-compatible-enum
is the first.

[PATCH 08/17] dt-bindings: samsung: exynos-pmu: add specific compatibles for existing SoC

[Krzysztof Kozlowski]

Samsung Exynos SoC reuses 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.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

---

I propose to take the patch through Samsung SoC (me). See cover letter
for explanation.

[PATCH 14/17] arm64: dts: exynos7: add specific compatibles to several blocks

[Krzysztof Kozlowski]

Exynos7 reuses 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 Exynos7 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.

[PATCH 17/17] arm64: dts: exynosautov9: add specific compatibles to several blocks

[Krzysztof Kozlowski]

ExynosAutov9 reuses 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 ExynosAutov9 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.

You didn't honor (or even comment) Krzysztof's proposal to take the
whole patchset via his tree (marked above). Was there some off-list
agreement?

It was also written in the PWM patch itself (under changelog ---) and
expressed with my "applied" response when I took everything. I am
sending now another set, also touching PWM.

I had read all that and then looking at patchwork saw that you had
marked all other patches in the series as "handled-elsewhere" and only
this one was left as "new", so I assumed that, well, everything else was
handled elsewhere and I was supposed to pick this one up...

I'll drop this one.

I didn't mark it as handled-elsewhere, but my expectation was that you
might want to send an Ack only.

For today's series by Krzysztof I acked and marked the patch as
handled-elsewhere (together with the rest of the series that isn't pwm
related). So you have to consult your inbox if you still want to send an
Ack for that one.

Best regards
