But there is a dependency. Your commit uses undocumented vendor prefix which introduces warnings. New warnings: Documentation/devicetree/bindings/pinctrl/ambarella,cv75-pinctrl.example.dtb: pinctrl@e4010000 (ambarella,cv75-pinctrl): 'ambarella,drive-strength-syscon', 'ambarella,pull-syscon' do not match any of the regexes: '^#.*', https://gitlab.com/robherring/linux-dt/-/jobs/17038310909 BTW, this commit of yours: 9c2932badcd3e3c0fc630eac5ff2bfd5fadf93f1 does not even build, so a make error. > > But if you tell me "revert the patch" I will simply revert the patch > because I trust you, it doesn't really matter why. I think Ambarella won't be picked up, because of total mess with patchsets, thus Rob should just take the vendor prefix... except there is no vendor prefix patch to take, since it is squashed with other work. I don't get why this became so messy and have no clue how this should be fixed, except revert which is sad churn-type of work. Best regards, Krzysztof
