From 115eea4e91049a42d81e5284cbb0f50acab6eb39 Mon Sep 17 00:00:00 2001 From: Svante Olofsson Date: Fri, 9 Sep 2005 13:02:48 -0700 Subject: [PATCH] [PATCH] dvb: usb: digitv: support for nxt6000 demod Add support for the NXT6000-based digitv-box. Add .get_tune_settings callback for the NXT6000 to have a min_tune_delay of 500ms.
