From 8e739090d6cdd43ddf938a3899c4f929db8d5ba8 Mon Sep 17 00:00:00 2001 From: Darron Broad Date: Sat, 11 Oct 2008 11:31:41 -0300 Subject: V4L/DVB (9225): MFE: Add configurable gate control This adds a configurable (one per card) gate control option for multi-frontend. Prior to this point gate control was assumed to be on the primary frontend, this is a fault when the gate to the analogue section is on the secondary which is the default for both the HVR-3000 and HVR-4000 in MFE.
