An illustration of what's considered a typical media device may help people to better understand the contents of the media infrastructure API docbook. So, add it. Signed-off-by:Mauro Carvalho Chehab <mchehab@osg.samsung.com>

The Docbook mistakenly makes to believe that all needed APIs for media devices are there. Add a note there pointing that some sub-devices are actually be controlled via ALSA API. Signed-off-by: -

The list of standards at the media docbook is incomplete, and it is mentioning that the DVB-S2 & friends is "currently being updated". That's wrong, as such update occurred back in 2008. So, provide a more complete list of supported standards and add a reference to the actual list. Signed-off-by: -

The ucblocks register is probably a counter and not a rate; assume it is so and change the calculations as required. Signed-off-by:

Frontend bandwidth calculation overflows on very high DVB-S/S2 symbol rates. Use mult_frac() macro in order to keep calculation correct. Signed-off-by:

Implement V4L2 subdevice tuner and core ops. After that this driver is hybrid driver implementing both V4L2 and DVB ops. Signed-off-by:

* Rename device state from 's' to 'dev'. * Move single include to driver private header. * Change error handling type of each function to one I tend use nowadays. * Remove dummy register write from init. Even Windows driver does this multiple times remove it as I have never seen any I2C errors. * Define I2C client pointer for each function and use it. * Do not clean tuner ops during driver remove - not needed. * Disable sysfs device bind / unbind. We are not allowed manually bind / unbind device from the driver currently. * Rename some other variables. Signed-off-by:

Update synthesizer calculation to model I prefer nowadays. It is mostly just renaming some variables to ones I think are most standard. Also add 'schematic' of synthesizer following my current understanding. Signed-off-by:

This code works fine but static checkers complain. The test_bit() function takes the bit number and not a mask. Then the other issue is that we were using USB_STATE_URB_BUF which is BIT(0) instead of URB_BUF. Also we were open coding that instead of using the test/clear/set_bit() functions. Signed-off-by:

The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a connector that can be used to hook up an adv7511 transmitter or an adv7842 receiver daughterboard. This device is used within Cisco but is sadly not available outside of Cisco. Nevertheless it is a very interesting driver that can serve as an example of how to support HDMI hardware and how to use the popular adv devices. Signed-off-by:

This makes it easier for the bridge driver to just passthrough such events to the corresponding device node. Signed-off-by:

All drivers use custom notifications, in particular when source changes. The bridge only has to map the subdev that sends it to whatever video node it is connected to. Signed-off-by:

vb2_buffer_done() already allows STATE_QUEUED, but currently only when not streaming. It is useful to allow it while streaming as well, as this makes it possible for drivers to requeue buffers while waiting for a stable video signal. Signed-off-by:

Replace the dummy video format operations by pad format operations that configure the output format. Copied from the adv7604 driver. Note: while arch/blackfin/mach-bf609/boards/ezkit.c uses adv7842_platform_data this source has not been updated because it is broken since the very beginning. It depends on a struct adv7842_output_format that does not exist. And besides that gcc has no support for bf609 so nobody can compile it except by installing a toolchain from ADI. Signed-off-by:

DVBv3 is a legacy API. Drivers should use DVBv5, in order to support modern applications. So, implement UCB using dvbv5. Signed-off-by:

Use const on the static data, as gcc may optimize better the code. Also, would prevent that some code would override the data there. Signed-off-by:

Add in all the likely values for setting fec on tuning. Some values yet to be tested but very likely to be correct. In the very unlikely event that these are wrong tuning with FEC_AUTO will still work. Signed-off-by:

If set, all the other drivers reset no_base_addr on failure to attach - git commit for this being added to some of them seems to be eccd15aa This driver has been floating around outside the mainline for so long it hasn't had this fix, so add it in. Whilst here tidy surrounding code to fix style issues. Signed-off-by:

Previous version of this driver had a memset before every call to cmd. This meant the default value of cmd.arg[1] was zero unless burst is set. Make sure it remains zero. Also fe_sec_mini_cmd_t is an enum, so test against it. Signed-off-by:
