HackRF SDR device has both receiver and transmitter. There is limitation that receiver and transmitter cannot be used at the same time (half-duplex operation). That patch implements transmitter support to existing receiver only driver. Signed-off-by:

Implement single funtion, hackrf_set_params(), which handles all needed settings. Controls and other IOCTLs are just wrappers to that function. That way we can get easily better control what we could do on different device states - sleeping, receiving, transmitting. Signed-off-by:

Antti Palosaari authored
Add new RF tuner gain control named RF Gain. That is aimed for first amplifier chip right after antenna connector. There is existing LNA Gain control, which is quite same, but it is aimed for cases amplifier is integrated to tuner chip. Some designs have both, as almost all recent tuner silicons has integrated LNA/RF amplifier in any case. Signed-off-by:

SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter has DAC (Digital-to-Analog Converter). Originally I though it could be good idea to have own type for receiver and transmitter, but now I feel one common type for SDR is enough. So lets rename it. Signed-off-by:

Prepare to divide videobuf2 - Separate vb2 trace events from v4l2 trace event. - Make wrapper functions that will move to v4l2-side. - Make vb2_core_* functions that will remain in core-side. - Add a callback function table for buffer operation which makes vb2-core to be able to invoke a v4l2-side functions. - Rename internal functions as vb2_*.

MFC driver never delivered EOS event to apps feeding constantly its capture buffer with fresh buffers. The patch fixes it by marking last buffers returned by MFC with MFC_BUF_FLAG_EOS flag and firing EOS event on de-queuing such buffers. Signed-off-by:

In videobuf2 dma-sg memory types the prepare and finish ops, instead of passing the number of entries in the original scatterlist as the "nents" parameter to dma_sync_sg_for_device() and dma_sync_sg_for_cpu(), the value returned by dma_map_sg() was used. Albeit this has been suggested in comments of some implementations (which have since been corrected), this is wrong.

The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens. Signed-off-by:

Now that the Demux kABI is documented at device-drivers.xml, remove it from the API docbook. Signed-off-by: -
Mauro Carvalho Chehab authored
There are several stuff at media's kdapi.xml that don't belong there, as it documents the Kernel internal ABI, and not the userspace API. Add the documentation here. The hole kdapi.xml will be removed on a latter patch, after we finish documenting what's there at the proper places. Signed-off-by: -

While we can't document #defines, documenting enums are well supported by kernel-doc. So, convert the bitmap defines into an enum. Signed-off-by: -
Mauro Carvalho Chehab authored
The usage of #define at the kABI is fine, but it doesn't allow adding a proper description. As those defines deserve a proper documentation, let's convert them into an enum and document them at device-drivers DocBook. Signed-off-by: -

The dvb/kdapi.tmpl has already an extensive documentation about this callback. Now that we've added function typedefs at kernel-doc, add such documentation at demux.h, for it to appear at device-drivers DocBook. Signed-off-by: -

A typedef function looks more likely a function and not a normal typedef. Change the code to use the output_function_*, in order to properly parse the function prototype parameters. Signed-off-by: -

The current typedef parser only works for non-function typedefs. As we need to also document some function typedefs, add a parser for it. Signed-off-by: -

The DVB core has a provision for other frontend sources, but no drivers use it. The kdapi.xml contains provision for some other frontend source types, but it is not in sync with the code. So, remove the unused types and sync both files. Signed-off-by:

This enum is not actually used anymore. The only value used from the enum is DMX_OK, passed as a parameter on two callbacks. Yet, this value is not used anywhere. So, just remove it. Signed-off-by: -
Mauro Carvalho Chehab authored
There are two callbacks still not documented: .//drivers/media/dvb-core/demux.h:422: warning: No description found for parameter 'get_pes_pids' .//drivers/media/dvb-core/demux.h:422: warning: No description found for parameter 'get_stc' The purpose of first one is clear. The second one is used only on the obsolete av7110 driver, and its purpose is not clear, as it just returns a 64-bit word from the firmware to userspace. Let's document get_pes_pids and mark get_stc as private, adding a comment to not use it, while this is not documented. Signed-off-by: -

There are a few inconsistencies between the old documentation that got imported into the header and the current status. Update them, and use the proper doc-nano nomenclature for struct artuments "@", instead of foo(). Signed-off-by: -
Mauro Carvalho Chehab authored
The DocBook/media/dvb/kdapi.xml contains the description of the kABI for DVB. The problem is that, by being maintained on a separate file and not being updated for years, it got outdated. So, for example, some callback parameters were changed, but the DocBook were still using the old stuff. As a first step to fix it, let's move the documentation of struct dmx_demux into demux.h and fix the parameters used there. For now, don't document any other field nor touch the descriptions that got moved, letting this job to other patches. That makes easier to review the patch. PS.: Please notice that an additional patch will be needed in order to fix the return values (some uses non-existent return codes) and to the functions and callbacks mentioned at the descriptions.
