From be718c2ee751899a991924e3fa346b293d170688 Mon Sep 17 00:00:00 2001 From: Hartmut Hackmann Date: Sat, 7 Oct 2006 00:45:23 +0200 Subject: Support status readout for saa713x based FM radio From: Hartmut Hackmann This patch adds readout for stereo and signal level for saa713x cards which use the saa713x as FM demodulator. These are many cards based on saa7133, tda8290 and tda8275a. FM channel search should work now.
