As a result, the tuner may not be taken out of reset before attempting initialization in the analog driver. This problem was not seen before with the EVGA inDtube, since that particular board has the analog GPIO setup to include taking the tuner out of reset. Thanks to Andreas Lunderhage for testing patches and providing a remote debug environment for the Pinnacle 320e.
