From a9686e0d204e3faa544434c709ccb599f8165252 Mon Sep 17 00:00:00 2001 From: Andrew de Quincey Date: Mon, 22 May 2006 10:31:40 -0300 Subject: V4L/DVB (3935): Add missing pll gate control calls I'd missed some of these out, breaking the av7110 tuning. I then checked for more and added them in where necessary. They may not actually be necessary in all these locations, but if not, they'll simply have no effect. Add small delay to stv0299 pll gate control to fix tuning problems.
