Add the necessary plumbing to make it possible to replace the switch by a table driven implementation. The ioctls ops can either be called directly, or by calling a small function that does some additional work if needed. Signed-off-by:

Add ".has_radio = 1" for BTTV_BOARD_MAGICTVIEW061 because there are some CHP05x/CHP06x boards with a radio tuner. I still have an analog Askey Magic TView card (CHP051, PCI 144f:3002) which I use for radio only. This worked fine with kernel 2.6.37 (openSUSE 11.4), but no longer works with kernel 3.1.10 (openSUSE 12.1). The reason apparently is that ".has_radio = 1" is missing in bttv-cards.c for BTTV_BOARD_MAGICTVIEW061; when I add this line and recompile the kernel, radio is working again. The line is still missing in the latest git tree, for which I have generated the attached patch. I can't test what will happen for CHP05x/CHP06x devices without radio; however, it seems that other cards also have the problem that there are some boards with radio and some without, so I hope that this can be sorted out.

When video endpoint is configured as bulk, a ZLP is sent after every video frames with size as multiple of 512 bytes. This is done so that host can detect end of transfer and pass data for processing. Still, frames that are multiple of 16K in size gets dropped. The ZLP sent by camera is ignored by uvc_video_decode_bulk(). The makes sure that the ZLP is not part of a video frame before ignoring it. If ZLP follows a video frame, then it triggers completion callback. [mchehab@redhat.com: Fix a small CodingStyle issue] Signed-off-by:

Several developers have reported that the lack of macros for the struct uvc_xu_control_query query field in uvcvideo.h was confusing and forced them to look at the driver source code to find out what applications were supposed to pass in that field. Add a comment to the header to clarify the expected usage of the query field. Reported-by:

This patch simply fixes some logging calls: - Use KERN_INFO when printing the chip status. - Add a missing space when logging the drxk_gate_ctrl call. - Use the same logging text as always if the scu_command in GetQAMLockStatus fails. Signed-off-by:

Currently there are two different implementations (in the firmware) for the QAM demodulator command: one takes 4 and the other takes 2 parameters. The driver shows an error in dmesg When using the 4-parameter command with firmware that implements the 2-parameter command. Unfortunately this happens every time when chaning the frequency (on DVB-C). This patch simply makes configurable, how many command parameters will be used. All existing drxk_config instances using the "drxk_a3.mc" were updated because this firmware is the only loadable firmware where the QAM demodulator command takes 4 parameters. Some firmwares in the ROM might also use it. The drxk instances in the em28xx-dvb driver were also updated to silence the warnings. If no qam_demod_parameter_count is given in the drxk_config struct, then the correct number of parameters will be auto-detected.

IQM_AF_CLKNEG_CLKNEGDATA__M is 0x2 and IQM_AF_CLKNEG_CLKNEGDATA_CLK_ADC_DATA_POS is 0. (clkNeg | 0x2) is never equal to zero so the condition can never be true. I consulted with Ralph Metzler and the '|' should be changed to a '&'. Signed-off-by:

Commit 7a6f6c29 (cx231xx: use URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer for URB twice. This works for the URBs allocated with usb_alloc_urb(), as those are allocated from cohernent DMA pools, but the flag was also added for the VBI and audio URBs, which have a manually allocated area. This leaves the random trash in the structure after allocation as the DMA address, corrupting memory and preventing VBI and audio from working. Letting the USB core map the buffers solves the problem. Signed-off-by:

Most calls to cx231xx_capture_start() already use the values from TRANSFER_TYPE, but cx231xx_capture_start() and cx231xx_initialize_stream_xfer() were hand coding the values. Use the named values (81 is never passed in), and simplify cx231xx_capture_start(), as the switch statements were identical and pcb_config->config_num is a u8, so any non-zero config got the same result.

The firmwares are there at the same place for a long time. However, each time I need to remember where it is, I need to seek at the net. The better is to just add a logic at the get_dvb_firmare script, in order to obtain it from a reliable source. Cc: Steven Toth <stoth@kernellabs.com> Signed-off-by: -

After this patch, the MEDIA*_SUPPORT will be used as a filter, exposing only devices that are pertinent to one of the 3 V4L types: webcam/grabber, radio, analog TV. Signed-off-by: -

In the past, it was possible to have either DVB or V4L2 core as module and the other as builtin. Such config never make much sense, and created several issues in order to make the Kconfig dependency to work, as all drivers that depend on both (most TV drivers) would need to be compiled as 'm'. Due to that, the VIDEO_MEDIA config option were added. Instead of such weird approach, let's just use the MEDIA_SUPPORT =y or =m to select if the media subsystem core will be either builtin or module, simplifying the building system logic. Also, fix the tuners configuration, by enabling them only if a tuner is required. So, if just webcam/grabbers support is selected, no tuner option will be selected. Also, if only digital TV is selected, no analog tuner support is selected. That removes the need of using EXPERT customise options, when analog TV is not selected. Signed-off-by: -

Change the main items to: <m> Multimedia support ---> [ ] Cameras/video grabbers support [ ] Analog TV support [ ] Digital TV support [ ] AM/FM radio receivers/transmitters support [ ] Remote Controller support This provides an interface that is clearer to end users that are compiling the Kernel, and will allow the building system to automatically unselect drivers for unused functions.

xc5000 is just a tuner, not a decoder, so both DMB-TH and ISDB-T should work properly there: it is just a matter of teaching the driver what saw filter should be used and how to calculate the center frequency. Requested-by:
