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@...8000: 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@...8000: 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
