I see the Tegra clock driver provides both a "cml0" and a "cml1" clock. Are both of those used for PCIe? If so, then why doesn't the driver and this DT change include both cml0 and cml1? If not, then please note that the clock-names property doesn't have to match the name of the clock at the clock provider. This property names the clock inputs to the HW module. Hence, if the PCIe module only uses a single CML clock, it can quite legitimately name its clock input just "cml" rather than "cml0". In this case, you wouldn't need to make this change to the DT. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

OK, so the PCIe drivers' clock-names property may as well contain just cml then. Same for SATA. The clock name at the provider isn't relevant. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
