Must've crept back in while I was rebasing my v2 changes. Either way Kryzysztof, I settled on removing the ordinal based naming entirely. I could not get trying the ordinal names & then falling back cleanly enough for my liking, so I dropped the whole thing. > + - '#clock-cells' > + > +additionalProperties: false > + > +examples: > + - | > + clock-controller@38100000 { > + compatible = "microchip,mpfs-ccc"; > + reg = <0x38010000 0x1000>, <0x38020000 0x1000>, > + <0x39010000 0x1000>, <0x39020000 0x1000>; > + #clock-cells = <1>; > + clocks = <&refclk_ccc>, <&refclk_ccc>, <&refclk_ccc>, <&refclk_ccc>, > + <&refclk_ccc>, <&refclk_ccc>; > + clock-names = "pll0_ref0", "pll0_ref1", "pll1_ref0", "pll1_ref1", > + "dll0_ref", "dll1_ref"; > + };

The base for a patch series is generally the most recent rc1. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit.

Messed up squashing commits before sending v2... fixed locally & I'll respin later in the week. I tried to mark it "changes required" in patchwork so you'd not waste time on it but I think that got reverted?

Could have. The CI job messes with the state and then I do, and my scripts don't expect the state changing underneath it. Most users don't have PW accounts. Don't worry, I don't spend much time on failing patches. Rob

On PolarFire SoC there are 4 PLL/DLL blocks, located in each of the ordinal corners of the chip, which our documentation refers to as "Clock Conditioning Circuitry". PolarFire SoC is an FPGA, these are highly configurable & many of the input clocks are optional.
