At a later stage (when /lib/modules is available), all kernel modules that match “compatible” entries in the device tree are loaded. Hence to be able to use device tree for ADT7316, add of_device_id table which specifies the supported devices through compatible property. Note that there is a fall back path in i2c that will result in i2c_device_id table being used if there is no of_devcie_id table.
