Subject: [media] af9033: feed clock to RF tuner Author: Antti Palosaari <[email protected]> Date: Sat Aug 9 01:03:14 2014 -0300 IT9135 RF tuner clock is coming from demodulator. We need enable it early in demod init, before any tuner I/O. Currently it is enabled by tuner driver itself, but it is too late and performance will be reduced as some registers are not updated correctly. Clock is disabled automatically when demod is put onto sleep.
