Till, now following approaches have been taken to manage these data: -- SPEAr13xx platform keep it locally in the files defining platform functions. -- IMX has created a new ahci platform device as a child of platform device created by DT and then attached this data as the driver_data of ahci's dev->parent. Adding a driver_data field helps in using the same platform driver as that of created by DT.
