This patch adds audio DMA capture and ALSA mixer elements for the line input jack of the Hauppauge Nova-S-plus DVB-S PCI card. The Nova-S-plus has a WM8775 ADC that is currently not detected. This patch enables this chip and exports volume, balance mute and ALC elements for ALSA mixer controls. [mchehab@redhat.com: Changed the patch to only talk with wm8775 if board info says so. Also, added platform_data support, to avoid changing the behaviour for other boards, and fixed CodingStyle] [awalls@md.metrocast.net: Changed patch to make the WM8775_GID defintion bridge driver private and let the bridge driver set the value of v4l2_subdev.grp_id.] -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Andy Walls <awalls@md.metrocast.net>
