From: Hans Verkuil Date: Mon, 9 Jan 2006 20:21:32 +0000 (-0200) Subject: V4L/DVB (3317): msp3400: use v4l2_std_id and determine chip capabilities. X-Git-Tag: v2.6.16-rc1~663^2~13 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7560d7a4f9add362d60d4513033cf522c37adeea;p=linux-2.6 V4L/DVB (3317): msp3400: use v4l2_std_id and determine chip capabilities. - Replace old norm by the v4l2_std_id values. - Add code to correctly detect the various capabilities of the various msp chips. It's not yet used, that's going to be the next step.
