You ignored my comments from v1 - please don't. This is not accepted.

Also, please do not send new versions of patchset as reply to some other
threads. It's extremely confusing to find it under something else.

Best regards,
Krzysztof
Hi

Krzysztof,

Sorry for confusion created which replying this patch.

The only comment I got from v1 from you is to run make dtbs_check.

I ran that command I found the errors and fixed them and I ran the make dtbs_check again
before on v2 and made sure there are no errors.

Can you please tell me is there any steps I missed.
The comment was:
"This won't work. You need to update other entry."

and then a conditional: "If you test it with
`make dtbs_check` you will see the errors."

So let's run it together:

/home/krzk/dev/linux/linux/out/arch/arm64/boot/dts/qcom/sc7280-idp.dtb:
pci@1c08000: clocks: [[42, 55], [42, 56], [41, 0], [39, 0], [42, 50],
[42, 52], [42, 53], [42, 57], [42, 58], [42, 177], [42, 178], [42, 8],
[42, 21]] is too long

From schema:
/home/krzk/dev/linux/linux/Documentation/devicetree/bindings/pci/qcom,pcie.yaml

/home/krzk/dev/linux/linux/out/arch/arm64/boot/dts/qcom/sc7280-idp.dtb:
pci@1c08000: clock-names: ['pipe', 'pipe_mux', 'phy_pipe', 'ref', 'aux',
'cfg', 'bus_master', 'bus_slave', 'slave_q2a', 'tbu', 'aggre0',
'aggre1', 'ddrss_sf_tbu'] is too long


clocks and clock-names can be maximum 12 items, as defined by schema in
"properties:" section. You cannot extend it in one place to 13 but leave
12 in other, because both constraints are applicable.

If you test it, you will see the errors.

Best regards,
Krzysztof

Hi Krzysztof,

Sorry for very late reply.

If we increase the common definitions of clocks properties to "13" it is sufficient right.
