[PATCH 0/7] ARM: dts: artpec: cleanup with the help of dt-check-style

[PATCH 0/7] ARM: dts: artpec: cleanup with the help of dt-check-style

[Henrik Grimler]

Fix most of the warnings that are reported by
scripts/dtc/dt-check-style, to make the files use the preferred
style. By doing so the files become easier to read and maintain.

Sorting of nodes have been left out from this patchset, as that
creates a huge, un-reviewable, patch. After the patches some warnings
remain when dt-check-style (with Krzysztof's recent fixes [1]) is run
in strict mode:

  axis/artpec6.dtsi:77: [child-name-order] child node 'psci' out of name order
  axis/artpec6.dtsi:80: [property-name] property name "psci_version" is using discouraged style
  axis/artpec6.dtsi:82: [property-name] property name "system_reset" is using discouraged style
  axis/artpec6.dtsi:91: [child-name-order] child node 'ext-clk' out of name order
  axis/artpec6.dtsi:97: [child-name-order] child node 'eth-phy-ref-clk' out of name order
  axis/artpec6.dtsi:103: [child-name-order] child node 'clkctrl' out of name order
  axis/artpec6.dtsi:127: [child-name-order] child node 'interrupt-controller' out of name order
  axis/artpec6.dtsi:134: [child-name-order] child node 'cache-controller' out of name order
  axis/artpec6.dtsi:163: [child-name-order] child node 'pcie' out of name order
  axis/artpec6.dtsi:233: [child-name-order] child node 'amba' out of name order
  axis/artpec6.dtsi:292: [child-address-order] child node @f8010000 out of address order
  axis/artpec6.dtsi:314: [property-name] property name "snps,wr_osr_lmt" is using discouraged style
  axis/artpec6.dtsi:315: [property-name] property name "snps,rd_osr_lmt" is using discouraged style
  axis/artpec6.dtsi:324: [child-name-order] child node 'rx-queues-config' out of name order

Fixing these are left for the future.

[PATCH 1/7] ARM: dts: axis: artpec6: avoid _ in node names

[Henrik Grimler]

Node names should preferably not use _, use - instead. Fixes
dt-check-style strict mode warnings:

  axis/artpec6.dtsi:91: [node-name] node name "ext_clk" is using discouraged style
  axis/artpec6.dtsi:97: [node-name] node name "eth_phy_ref_clk" is using discouraged style
  axis/artpec6.dtsi:189: [node-name] node name "pcie_ep" is using discouraged style

This will change the name of the clock. Did you verify that it is fine?

[PATCH 2/7] ARM: dts: axis: artpec6: align all continued lines

[Henrik Grimler]

dt-check-style in strict mode reports that there are a bunch of
multiline properties that are not aligned, fix them to make the dts
easier to follow. Fixes dt-check-style warnings like:

  axis/artpec6.dtsi:290: [continuation-alignment] continuation should align to column 34 (to < or ")

b4 / get_maintainer.pl picks you up:

  $ ./scripts/get_maintainer.pl arch/arm/boot/dts/axis/*
  ..
  Krzysztof Kozlowski <krzk+dt@kernel.org> (maintainer:OPEN FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
  ..

I believe ARTPEC-6 patches has gone through the ARM SOC tree in the
past, so maybe that makes the most sense now also. Will update the
cover letter in next version to suggest this.

Thanks for looking at the patches in any case, will fix your comments!

Henrik Grimler

[PATCH 3/7] ARM: dts: axis: artpec6: use multiple tuples in regs and ranges

[Henrik Grimler]

When #size-cells > 1 it is preferred to have each entry as its own
tuple, to make it easier to identify addresses and sizes. Update
artpec6.dtsi to use preferred style to increase readability.

[PATCH 4/7] ARM: dts: axis: artpec6: sort all properties

[Henrik Grimler]

To make as easy as possible to read devicetree nodes, the properties
should be alphabetical, with a few exceptions (compatible, reg,
status, ..). Update the artpec-6 dtses to use preferred style. Issues
are detected by dt-check-style when run in strict mode as:

  axis/artpec6.dtsi:93: [property-order] property 'compatible' out of canonical order (should sort before '#clock-cells')

[PATCH 5/7] ARM: dts: axis: artpec6: add more blank lines

[Henrik Grimler]

The status property, and each child node, should preferably have empty
lines before them to increase readability. dt-check-style in strict
mode reports this type of issue as:

  axis/artpec6.dtsi:186: [required-blank-lines] "status" must be preceded by a blank line

Fix all occurences.

[PATCH 6/7] ARM: dts: axis: artpec6: put inline comments on same line as entries

[Henrik Grimler]

By having the comments next to the data they describe it is easier to
read the property. This fixes indent-consistent and
continuation-alignment warnings from dt-check-style in strict mode,
e.g. warnings like:

  axis/artpec6.dtsi:170: [indent-consistent] indent mismatch (expected depth 2 * '\t')
  axis/artpec6.dtsi:172: [continuation-alignment] continuation should align to column 26 (to < or ")

Also shorten one of the comments a bit so that the entire line fits
under 100 chars.

[PATCH 7/7] ARM: dts: axis: artpec6: add empty lines before empty queue nodes

[Henrik Grimler]

For better readability child nodes should be preceded by an empty
line, and closing braces should be on their own line. Both issues are
reported by dt-check-style in strict mode, e.g.

  axis/artpec6.dtsi:212: [required-blank-lines] child node must be preceded by a blank line
  axis/artpec6.dtsi:321: [node-close-alone] closing brace must be on its own line

Updated the dts to use preferred style.

These are false positives. Original code is readable.
