Why this cannot be one patch? > The only commonality between the patches is that they both enable PCIe drivers. However, the patch for J721E PCIe driver only enables the controller for EP mode, as Host mode is already present. On the other hand, the patch for Keystone PCIe driver enables both Host and EP mode of operation. Also as I mentioned, they belong to different SoCs with different PCIe controllers, so I chose to keep them separate. If I squash both the patches, the subject like: "Enable PCIe drivers for TI SoCs" would be too generic, as TI would have more SoCs in the future. Hence, the squashed patch with this subject might mislead in future. If you insist me squashing the patches, then would the following subject be acceptable: "Enable J721E and Keystone PCIe drivers" for the squashed patch? > > Best regards, > Krzysztof
