From 79150c25be2d0daef58a7d32afc06b4955fabb54 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sun, 13 Jan 2008 20:01:07 -0500 Subject: tda18271: provide a choice whether to perform rf cal on init or on first tune From: Michael Krufky If module option "cal" is set to 1, the ~22 sec rf tracking filter calibration sequence will be invoked on startup. Otherwise, the calibration will take place during the first tune.
