From b8d4c235d50f8512bbc9d67730c24da3309b0307 Mon Sep 17 00:00:00 2001 From: Thomas Kaiser Date: Thu, 27 Apr 2006 21:45:20 -0300 Subject: [PATCH] V4L/DVB (3934): Support new dvb-ttusb-budget boards with stv0297 Added config switch to stv0297 to control i2c STOP during write behaviour. Update frontend init in dvb-ttusb-budget. Enable i2c STOP on other users of stv0297.
