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 --- drivers/media/video/cx88/cx88.h | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'drivers/media/video/cx88/cx88.h') diff --git a/drivers/media/video/cx88/cx88.h b/drivers/media/video/cx88/cx88.h index c9981e77416a..aaf7d12b77db 100644 --- a/drivers/media/video/cx88/cx88.h +++ b/drivers/media/video/cx88/cx88.h @@ -33,6 +33,7 @@ #include #include #include +#include #include "btcx-risc.h" #include "cx88-reg.h" @@ -273,6 +274,9 @@ struct cx88_board { enum cx88_board_type mpeg; unsigned int audio_chip; int num_frontends; + + /* Used for I2S devices */ + int i2sinputcntl; }; struct cx88_subid { @@ -379,6 +383,7 @@ struct cx88_core { /* I2C remote data */ struct IR_i2c_init_data init_data; + struct wm8775_platform_data wm8775_data; struct mutex lock; /* various v4l controls */ @@ -398,17 +403,21 @@ static inline struct cx88_core *to_core(struct v4l2_device *v4l2_dev) return container_of(v4l2_dev, struct cx88_core, v4l2_dev); } -#define call_all(core, o, f, args...) \ +#define WM8775_GID (1 << 0) + +#define call_hw(core, grpid, o, f, args...) \ do { \ if (!core->i2c_rc) { \ if (core->gate_ctrl) \ core->gate_ctrl(core, 1); \ - v4l2_device_call_all(&core->v4l2_dev, 0, o, f, ##args); \ + v4l2_device_call_all(&core->v4l2_dev, grpid, o, f, ##args); \ if (core->gate_ctrl) \ core->gate_ctrl(core, 0); \ } \ } while (0) +#define call_all(core, o, f, args...) call_hw(core, 0, o, f, ##args) + struct cx8800_dev; struct cx8802_dev; -- cgit v1.2.3
