From 085542dc8611d969ef698120c98288e24d5f4f9d Mon Sep 17 00:00:00 2001 From: Andrew de Quincey Date: Tue, 18 Apr 2006 17:47:10 -0300 Subject: [PATCH] V4L/DVB (3856): Convert sp887x to refactored tuner code Convert to tuner_ops calls. Remove pll function pointers from structure. Remove unneeded tuner calls. Add i2c gate control function.
