From 15ba8202e6f9417abd1d6831aca4237407e0ff0b Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sat, 9 Aug 2014 00:08:57 -0300 Subject: [PATCH] [media] af9035: enable AF9033 demod clock source for IT9135 Integrated RF tuner of IT9135 is connected to demod clock source named dyn0_clk. Enable that clock source in order to provide stable clock early enough.
