I found a datasheet for lgdt3305 it does indeed have a reset pin at pin 37 active low with internal pull up. I will try to attach a probe to that pin and walk through all of the GPIO until I find the right one. I hope that lgdt3304 and lgdt3305 are pin compatible otherwise I might not have much success. -----Original Message----- From: linux-media-owner@xxxxxxxxxxxxxxx [mailto:linux-media-owner@xxxxxxxxxxxxxxx] On Behalf Of Steven Toth Sent: Thursday, June 27, 2013 1:59 PM To: Carl-Fredrik Sundstrom Cc: linux-media@xxxxxxxxxxxxxxx Subject: Re: lgdt3304 > I get so far that I can load a basic driver by modifying the existing > saa716x driver, I can detect the TDA18271HD/C2, but I fail to detect > the > LGDT3304 when attaching it using the 3305 driver.
