If I see it correctly, the regmap-irq (main-irq-reg support) changes are not targeted to linux 5.1. To me it looks like getting them to MFD via Linus' tree will take a while. The MFD part depends on the regmap-irq changes and I think that most other subsystems want to have the MFD changes in before taking rest of the driver in their trees. So it will be a while untill all the changes are in. It would really be nice to have the drive in-tree sooner - hence I ask if theres a way. (I don't want to push, just ask if it is possible :]) Best Regards Matti Vaittinen
