From a98af2246b3d0e85566b3b489ffbc8018b21b4a3 Mon Sep 17 00:00:00 2001 From: Andrew de Quincey Date: Tue, 18 Apr 2006 17:47:10 -0300 Subject: [PATCH] V4L/DVB (3859): Convert s5h1420 to refactored tuner code Convert to tuner_ops calls. Remove pll function pointers from structure. Remove unneeded tuner calls. Add i2c gate control function.
