From 6951803c2402d1af0e76df051cc9b117f504550f Mon Sep 17 00:00:00 2001 From: Lawrence Rust Date: Sun, 6 Feb 2011 17:46:12 -0300 Subject: [media] Add proper audio support for Nova-S Plus with wm8775 ADC 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 Signed-off-by: Andy Walls --- include/media/wm8775.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'include/media') diff --git a/include/media/wm8775.h b/include/media/wm8775.h index 60739c5a23ae..d0e801a9935c 100644 --- a/include/media/wm8775.h +++ b/include/media/wm8775.h @@ -32,4 +32,13 @@ #define WM8775_AIN3 4 #define WM8775_AIN4 8 + +struct wm8775_platform_data { + /* + * FIXME: Instead, we should parametrize the params + * that need different settings between ivtv, pvrusb2, and Nova-S + */ + bool is_nova_s; +}; + #endif -- cgit v1.2.3
