From e6d837f4a64a734f61339d030bc2da2459b636d7 Mon Sep 17 00:00:00 2001 From: Steven Toth Date: Thu, 27 Aug 2009 17:08:21 -0400 Subject: SAA7164: HVR2250 changes related to attach time tuner configuration From: Steven Toth Ensure that by default all tuners are set correctly to master/slave mode. For all HVR2250's, ensure slave based tuners are caliberated during attach to avoid locking problems on tuner# above channel 91. HVR2200 tuner attach time to be reviewed in a future patch.
