RE: [PATCH v1 02/10] dt-binding: clk: ast2700: Add binding for Aspeed AST27xx Clock

Hi Krzk,

I will separate clock part in the v3 patch into Ryan's clock series.
Missing commit msg.

A nit, subject: drop second/last, redundant "bindings". The "dt-bindings" prefix
is already stating that these are bindings.
See also:
https://elixir.bootlin.com/linux/v6.7-rc8/source/Documentation/devicetree/bin
dings/submitting-patches.rst#L18

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory your
patch is touching. For bindings, the preferred subjects are explained here:
https://www.kernel.org/doc/html/latest/devicetree/bindings/submitting-patch
es.html#i-for-patch-submitters
Agree, already fixed in another commit in Ryan's series.

This is supposed to be part of bindings adding the clock controller.
