From ec7c15b58f34015df182e909fbb80674211daf54 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Sun, 14 Apr 2013 12:39:09 -0300 Subject: [PATCH] [media] bttv: Add noname Bt848 capture card with 14MHz xtal Add support for noname Bt848 capture-only card (3x composite, 1x S-VHS) with 14MHz crystal: http://www.rainbow-software.org/images/hardware/bt848_.jpg 14MHz PLL was not supported by bttv driver until now.
