Thanks for the reminder. I have put it on my staging branch for now. Once rc3 gets tagged with irqchip related changes, I will move this over to next. Now, that said, Please consider converting Documentation/devicetree/bindings/pci/pci-keystone.txt to yaml sometime in near future, if possible. We might also want to spend a little more time with W=2 dtbs build and dtbs_check to cleanup. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
