From 8a4e786660f512b029b56d94d1b8f0201e67aab3 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Tue, 4 Dec 2012 11:30:00 -0300 Subject: [PATCH] [media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2 This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog video capture support and depends on VIDEO_V4L2 itself. With VIDEO_AU0828_V4L2 disabled, the driver will only support digital television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2 enabled, the driver will be built with the analog v4l2 support included. By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to preserve the original behavior.
