From 136cafbf4a024b52ba0a10627217f03cea9ff9f8 Mon Sep 17 00:00:00 2001 From: Patrick Boettcher Date: Tue, 19 Sep 2006 12:51:33 -0300 Subject: [PATCH] V4L/DVB (4646): Misc. changes, DiB3000MC, MT2060 Changed the attach-function of the dib3000mc-driver to return only one frontend. In case of multiple dib3000-chips on one board, one has to call the i2c-enumeration manually before. Added a field to Microtune 2060 config to output the clock to other tuners/device on a board.
