From 606cf9caeb3b908426757924bfdce85cb854aa81 Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sat, 20 Jan 2007 01:56:04 -0300 Subject: [PATCH] V4L/DVB (5093): Pvrusb2: Emit VIDIOC_S_TUNER correctly Audio mode changes are not private to the audio chip - other I2C modules need to see this as well. And since the command in question is VIDIOC_S_TUNER which is a standard v4l2 command, we really should be broadcasting it out. This change sets up a broadcast pathway for VIDIOC_S_TUNER and also eliminates the now redundant code from the audio chip handler. This fix enables stereo reception for the FM radio Signed-off-by: Mike Isely Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/pvrusb2/pvrusb2-audio.c | 10 +------- .../video/pvrusb2/pvrusb2-i2c-chips-v4l2.c | 15 +++++++----- .../video/pvrusb2/pvrusb2-i2c-cmd-v4l2.c | 23 +++++++++++++++++++ .../video/pvrusb2/pvrusb2-i2c-cmd-v4l2.h | 1 + 4 files changed, 34 insertions(+), 15 deletions(-) diff --git a/drivers/media/video/pvrusb2/pvrusb2-audio.c b/drivers/media/video/pvrusb2/pvrusb2-audio.c index a45ede0a8cf1..379645e481c6 100644 --- a/drivers/media/video/pvrusb2/pvrusb2-audio.c +++ b/drivers/media/video/pvrusb2/pvrusb2-audio.c @@ -43,13 +43,6 @@ static void set_stereo(struct pvr2_msp3400_handler *ctxt) pvr2_trace(PVR2_TRACE_CHIPS,"i2c msp3400 v4l2 set_stereo"); - if (hdw->input_val == PVR2_CVAL_INPUT_TV) { - struct v4l2_tuner vt; - memset(&vt,0,sizeof(vt)); - vt.audmode = hdw->audiomode_val; - pvr2_i2c_client_cmd(ctxt->client,VIDIOC_S_TUNER,&vt); - } - route.input = MSP_INPUT_DEFAULT; route.output = MSP_OUTPUT(MSP_SC_IN_DSP_SCART1); switch (hdw->input_val) { @@ -77,8 +70,7 @@ static void set_stereo(struct pvr2_msp3400_handler *ctxt) static int check_stereo(struct pvr2_msp3400_handler *ctxt) { struct pvr2_hdw *hdw = ctxt->hdw; - return (hdw->input_dirty || - hdw->audiomode_dirty); + return hdw->input_dirty; } diff --git a/drivers/media/video/pvrusb2/pvrusb2-i2c-chips-v4l2.c b/drivers/media/video/pvrusb2/pvrusb2-i2c-chips-v4l2.c index 16fa075a1eec..49773764383b 100644 --- a/drivers/media/video/pvrusb2/pvrusb2-i2c-chips-v4l2.c +++ b/drivers/media/video/pvrusb2/pvrusb2-i2c-chips-v4l2.c @@ -33,15 +33,17 @@ #define trace_i2c(...) pvr2_trace(PVR2_TRACE_I2C,__VA_ARGS__) #define OP_STANDARD 0 -#define OP_BCSH 1 -#define OP_VOLUME 2 -#define OP_FREQ 3 -#define OP_AUDIORATE 4 -#define OP_SIZE 5 -#define OP_LOG 6 +#define OP_AUDIOMODE 1 +#define OP_BCSH 2 +#define OP_VOLUME 3 +#define OP_FREQ 4 +#define OP_AUDIORATE 5 +#define OP_SIZE 6 +#define OP_LOG 7 static const struct pvr2_i2c_op * const ops[] = { [OP_STANDARD] = &pvr2_i2c_op_v4l2_standard, + [OP_AUDIOMODE] = &pvr2_i2c_op_v4l2_audiomode, [OP_BCSH] = &pvr2_i2c_op_v4l2_bcsh, [OP_VOLUME] = &pvr2_i2c_op_v4l2_volume, [OP_FREQ] = &pvr2_i2c_op_v4l2_frequency, @@ -54,6 +56,7 @@ void pvr2_i2c_probe(struct pvr2_hdw *hdw,struct pvr2_i2c_client *cp) int id; id = cp->client->driver->id; cp->ctl_mask = ((1 << OP_STANDARD) | + (1 << OP_AUDIOMODE) | (1 << OP_BCSH) | (1 << OP_VOLUME) | (1 << OP_FREQ) | diff --git a/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.c b/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.c index b1f6809625e8..c650e02ccd00 100644 --- a/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.c +++ b/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.c @@ -140,6 +140,29 @@ const struct pvr2_i2c_op pvr2_i2c_op_v4l2_volume = { }; +static void set_audiomode(struct pvr2_hdw *hdw) +{ + struct v4l2_tuner vt; + memset(&vt,0,sizeof(vt)); + vt.audmode = hdw->audiomode_val; + pvr2_i2c_core_cmd(hdw,VIDIOC_S_TUNER,&vt); +} + + +static int check_audiomode(struct pvr2_hdw *hdw) +{ + return (hdw->input_dirty || + hdw->audiomode_dirty); +} + + +const struct pvr2_i2c_op pvr2_i2c_op_v4l2_audiomode = { + .check = check_audiomode, + .update = set_audiomode, + .name = "v4l2_audiomode", +}; + + static void set_frequency(struct pvr2_hdw *hdw) { unsigned long fv; diff --git a/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.h b/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.h index 6a9bb46d0654..c838df6167f9 100644 --- a/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.h +++ b/drivers/media/video/pvrusb2/pvrusb2-i2c-cmd-v4l2.h @@ -31,6 +31,7 @@ extern const struct pvr2_i2c_op pvr2_i2c_op_v4l2_bcsh; extern const struct pvr2_i2c_op pvr2_i2c_op_v4l2_volume; extern const struct pvr2_i2c_op pvr2_i2c_op_v4l2_frequency; extern const struct pvr2_i2c_op pvr2_i2c_op_v4l2_size; +extern const struct pvr2_i2c_op pvr2_i2c_op_v4l2_audiomode; extern const struct pvr2_i2c_op pvr2_i2c_op_v4l2_log; void pvr2_v4l2_cmd_stream(struct pvr2_i2c_client *,int); -- 2.20.1
