On some of Qualcomm platforms the Global Clock Controller (GCC) doesn't
provide power domains. Move requirement for the '#power-domain-cells'
out of the common qcom,gcc.yaml into individual schema files. For the
platforms that do not provide power-domains, explicitly forbid having
the '#power-domain-cells' property.

Now as the gcc-qcs404 gained support for GDSC and requires using
the #power-domain-cells property, switch the qcom,gcc-qcs404.yaml schema
to use common gcc.yaml.

Clean the Qualcomm SoCs clock bindings:
1. Drop redundant "bindings" in title.
2. Correct language grammar "<independent clause without verb>, which
supports" -> "provides".
3. Use full path to the bindings header, so tools can validate it.
4. Drop quotes where not needed.

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.
Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.
So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

The 'qcom,gcc.yaml' file failed self-validation (dt_binding_check)
because it required a property to be either (3 entries big),
(3 entries big), or (7 entries big), but not more than one of those
things. That didn't make a ton of sense.
This patch splits all of the exceptional device trees (AKA those that
would have needed if/then/else rules) from qcom,gcc.yaml. It also
cleans up some cruft found while doing that.
After this lands, this worked for me atop clk-next with just the known
error about msm8998:
for f in \
Documentation/devicetree/bindings/clock/qcom,gcc-apq8064.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-ipq8074.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-msm8996.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-msm8998.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-qcs404.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-sc7180.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc-sm8150.yaml \
Documentation/devicetree/bindings/clock/qcom,gcc.yaml; do \
ARCH=arm64 make dtbs_check DT_SCHEMA_FILES=$f; \
done
I then picked this patch atop linux-next (next-20200129) and ran:
# Delete broken yaml:
rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml
ARCH=arm64 make dt_binding_check | grep 'clock/qcom'
...and that didn't seem to indicate problems.
Arbitrary decisions made (yell if you want changed):
- Left all the older devices (where clocks / clock-names weren't
specified) in a single file.
- Didn't make clocks "required" for msm8996 but left them as listed.
This seems a little weird but it matches the old binding.
Misc cleanups as part of this patch:
- Fixed schema id to not have "bindings/" as per Rob [1].
- Listed include files as per Stephen.
- sm8150 was claimed to be same set of clocks as sc7180, but driver
and dts appear to say that "bi_tcxo_ao" doesn't exist. Fixed.
- In "apq8064", "#thermal-sensor-cells" was missing the "#".
- Got rid of "|" at the end of top description since spacing doesn't
matter.
- Changed indentation to consistently 2 spaces (it was 3 in some
places).
- Added period at the end of protected-clocks description.
- No space before ":".
- Updated sc7180/sm8150 example to use the 'qcom,rpmh.h' include.
- Updated sc7180/sm8150 example to use larger address/size cells as
per reality.
- Updated sc7180/sm8150 example to point to the sleep_clk rather than
<0>.
- Made it so that gcc-ipq8074 didn't require #power-domain-cells since
actual dts didn't have it and I got no hits from:
git grep _GDSC include/dt-bindings/clock/qcom,gcc-ipq8074.h
- Made it so that gcc-qcs404 didn't require #power-domain-cells since
actual dts didn't have it and I got no hits from:
git grep _GDSC include/dt-bindings/clock/qcom,gcc-qcs404.h
Noticed, but not done in this patch (volunteers needed):
- Add "aud_ref_clk" to sm8150 bindings / dts even though I found a
reference to it in "gcc-sm8150.c".
- Fix node name in actual ipq8074 to be "clock-controller" (it's gcc).
- Since the example doesn't need phandes to exist, in msm8998 could
just make up places providing some of the clocks currently bogused
out with <0>.
- On msm8998 clocks are listed as required but current dts doesn't
have them.
