From 3b0d51afa026b87784d81e6a88522271a69ca7b9 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 9 Dec 2012 11:46:40 -0300 Subject: [PATCH] [media] fc0012: enable clock output on attach() We need feed clock to slave demodulator at the very beginning in case of dual tuner configuration. I am not sure if that configuration changes clock output divider or enable clock output itself...
