The vpbe driver can handle different platforms DM644X, DM36X and DM355. To differentiate between this platforms venc_type/vpbe_type was passed as part of platform data which was incorrect. The correct way to differentiate to handle this case is by passing different platform names. This patch creates platform_device_id[] array supporting different platforms and assigns id_table to the platform driver, and finally in the probe gets the actual device by using platform_get_device_id() and gets the appropriate driver data for that platform. Taking this approach will also make the DT transition easier.
