From 0c2c3851d68bcc621a0e4c3d3b9469da047ed7b7 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Wed, 24 Oct 2007 08:23:17 -0400 Subject: tuner: add i2c_gate_ctrl function to struct analog_tuner_ops From: Michael Krufky In some designs, the tuner silicon may be on an i2c bus behind an i2c gate, controlled by the analog demodulator. We already have a method to control such i2c gates when they are controlled by the digital demodulator, but in some hybrid designs, there may be an i2c gate controlled by each demodulator. For example, when in analog tuning mode, one would access the tuner by opening the i2c gate controlled by the analog demodulator, while when in digital tuning mode, one would access the tuner by opening the i2c gate controlled by the digital demodulator. We must add this callback function to analog_tuner_ops in order to handle such configurations.
