From be94351e592cb71fb61aa8eeed7bf3f877dc6fff Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Mon, 5 Sep 2011 22:10:05 -0300 Subject: [media] anysee: I2C gate control DNOD44CDH086A tuner module DNOD44CDH086A (NXP TDA18212) tuner module is not connected to demodulator I2C gate. Instead demodulator gate it uses external GPIO driven gate. Override demodulator I2C gate control with own in that case.
