Subject: [media] tda827x: improve recection with limit frequencies Author: Jose Alberto Reguero <[email protected]> Date: Sat Jul 16 08:38:13 2011 -0300 tda827x is currently taking the demod IF frequency into account while seeking for the proper tuner range. This is wrong, as the demod IF frequency has nothing to do with the tuner PLL.
