Some previous conversations between you and Lee are here: - https://lkml.org/lkml/2015/7/28/51 - https://lkml.org/lkml/2015/7/28/850 The MFD part and device tree part for the DA9062 OnKey are in the mainline v4.3-rc1 kernel now. Can I ask if there any barriers in the way for moving the DA9063 OnKey patch forward now please?
