From 4abe9f9d94e60303c30b1a9bbbc8e6532f6138cb Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sat, 5 May 2007 12:15:57 -0300 Subject: [PATCH] V4L/DVB (5633): Tuv1236d: move rf input switching code into dvb-pll This patch removes duplicate code from cx88-dvb and saa7134-dvb that handles rf input switching for the TUV1236d tuner. The functionality is added to dvb-pll, where all the other code that handles the TUV1236d is kept.
