Hi Peter, Thanks for your information,
And can you kindly suggest me, 1)How the probe will be called by comparing the name in driver and name given in board-files, or it will called based id_table which we fill for particular bus of that driver. 2)How the priority will be followed to call the drivers files like BT first and then HDMI driver.
