From c0038ce025e1d70076894e6a206a73fd37ad493d Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 22 Apr 2008 14:45:49 -0300 Subject: [PATCH] V4L/DVB (7338): ivtv: improve pal/secam module options, add tunerhz module option Allow options like pal=bgh, improve description of those options. Add tunerhz option: 50=card has 50Hz tuner, 60=card has 60Hz tuner.
