[PATCH v3 0/4] Krait Documentation conversion

[PATCH v3 0/4] Krait Documentation conversion

[Christian Marangi]

This series convert the krait-cc and the kpps-acc/gcc Documentation to
yaml.

This series comes form a split of a bigger series that got too big and
now hard to review.

While they are still more or less wrong and doesn't really reflect real
driver implementation, they are converted to prepare for a fixup later
when dts and driver are finally fixed.

Minor changes are done to the kpss-gcc driver and minor fixes are done to
the various affected dts to fix dtbs_check warning with the new introduced
schema.

v3:
- Update all Sob
- Rework kpss-gcc Documentation with the new finding
- Fix dtbs_check warning
v2:
- Fix bot error by adding missing #clock-cells

Changelog for previous series "Modernize rest of the krait drivers"
that was split to smaller series (only Documentation changes):
v7:
- Rework kpss-gcc Documentation (split patch for pure conversion and
  tweaks)
v6:
- Address comments from Rob
- Fix warning from make dtbs_check
v5:
- Address comments from Krzysztof
v4:
- Fix more dt-bindings bug errors
v3:
- Split Documentation files for kpss and krait-cc
v2:
- fix missing new line on patch 16 (krait-cc patch)

[PATCH v3 2/4] dt-bindings: arm: msm: Convert kpss-acc driver Documentation to yaml

[Christian Marangi]

Convert kpss-acc driver Documentation to yaml.
The original Documentation was wrong all along. Fix it while we are
converting it.
The example was wrong as kpss-acc-v2 should only expose the regs but we
don't have any driver that expose additional clocks. The kpss-acc driver
is only specific to v1. For this exact reason, limit all the additional
bindings (clocks, clock-names, clock-output-names and #clock-cells) to
v1 and also flag that these bindings should NOT be used for v2.

[PATCH v3 3/4] dt-bindings: arm: msm: Rework kpss-gcc driver Documentation to yaml

[Christian Marangi]

Rework kpss-gcc driver Documentation to yaml Documentation.
The current kpss-gcc Documentation have major problems and can't be
converted directly. Introduce various changes to the original
Documentation.

Add #clock-cells additional binding as this clock outputs a static clk
named acpu_l2_aux with supported compatible.
Only some compatible require and outputs a clock, for the others, set
only the reg as a required binding to correctly export the kpss-gcc
registers. As the reg is shared also add the required syscon compatible.

[PATCH v3 4/4] ARM: dts: qcom: fix various wrong definition for kpss-gcc node

[Christian Marangi]

Fix dtbs_check warning now that we have a correct kpss-gcc yaml
schema. Add additional qcom,kpss-gcc compatible to differentiate
devices where kpss-gcc should provide a clk and where kpss-gcc should
just provide the registers and the syscon phandle.
Add missing #clock-cells and remove useless clock-output-names for
ipq806x.
Add missing binding for msm8090 kpss-gcc node.

This is still not fixed and not tested. Since 4 versions of this
patchset (previously was part of other set).

I retract my review. Please test the bindings.

Thing is that I tested them and on my side I don't have such errors.

I'm using the linux-next branch. Should I use something else that have
newer schema files?

Also on other patch there are some error reported that are unrelated to
my change and that looks strange.

Then maybe update your dtschema because I can easily see them.

The other might be not be relevant, but this one is real and reproducible.

You are totally right. I didn't had the problem as I was updating the
dtschema with sudo pip3... and it wasn't updating the dtschema local to
the linux repo. Didn't know that and I could't understand why I didn't
had the error.
