V4L/DVB (6034): cx88: Add parameter to control radio deemphasis time constant
FM radio transmission use a preemphasis/deemphasis scheme to reduce
high-frequency noise. The cx88 audio decoder is supposedly set to no
deemphasis by the current driver.
However, the "no deemphasis" setting doesn't work. On my chip, cx23883, it
produces the same result as the 75 us time constant. Maybe the default
settings on the cx23881 are for 50 us?
Since the deemphasis time constant varies by country, allow setting it via a
module parameter.
