This is an hybrid board. However, for analog, it requires a new driver for saa7136. So, for now, let's just add support for Digital TV. Signed-off-by: -

When a v4l2-mem2mem context gets a STREAMOFF call on either its CAPTURE or OUTPUT queues, we should: * Drop the corresponding rdy_queue, since a subsequent STREAMON expects an empty queue. * Deschedule the context, as it now has at least one empty queue and cannot run. Signed-off-by:

In v4l2_m2m_try_schedule(), use the CAPTURE queue lock when accessing the CAPTURE queue, instead of relying on just holding the OUTPUT queue lock. Signed-off-by:

Use the same handlers where the structs are the same. Implement a new handler for link enumeration since struct media_links_enum is different on 32-bit and 64-bit systems. Signed-off-by:

I'm pasting the original code and my proposal on the commit message for make it easy to compare the two versions. Line 62 of cx25821-audio-upstream.h contains: char *_defaultAudioName = "/root/audioGOOD.wav"; Original code after replace kmemdup for kstrdup, and after fix return error code: if (dev->input_audiofilename) { dev->_audiofilename = kstrdup(dev->input_audiofilename, GFP_KERNEL); if (!dev->_audiofilename) { err = -ENOMEM; goto error; } /* Default if filename is empty string */ if (strcmp(dev->input_audiofilename, "") == 0) dev->_audiofilename = "/root/audioGOOD.wav"; } else { dev->_audiofilename = kstrdup(_defaultAudioName, GFP_KERNEL); if (!dev->_audiofilename) { err = -ENOMEM; goto error; } } Code proposed in this patch: if ((dev->input_audiofilename) && (strcmp(dev->input_audiofilename, "") != 0)) dev->_audiofilename = kstrdup(dev->input_audiofilename, GFP_KERNEL); else dev->_audiofilename = kstrdup(_defaultAudioName, GFP_KERNEL); if (!dev->_audiofilename) { err = -ENOMEM; goto error; } Signed-off-by:Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by:

The current logic was broken and too complex; while it works fine for DVB-S2/DVB-S, it is broken for ISDB-T. Make the logic simpler, fixes it for ISDB-T and make it clearer. Signed-off-by: -
Mauro Carvalho Chehab authored
This function is complex, and has different workflows, one for DVBv3 calls, and another one for DVBv5 calls. Break it into 3 functions, in order to make easier to understand what each block does. No functional changes so far. A few comments got improved. Signed-off-by: -

It turned out that some devices return less bytes then requested via i2c when ALL of the following 3 conditions are met: - i2c bus B is used - there was no attempt to write to the specified slave address before - no device present at the specified slave address With the current code, this triggers an -EIO error and prints a message to the system log. Because it can happen very often during device probing, it is better to ignore this error and bail out silently after the follwing i2c transaction success check with -ENODEV.

The em28xx driver obtains the timestamps using function v4l2_get_timestamp(), which produces a montonic timestamp. Fixes the warnings appearing in the system log since commit 6aa69f99 "[media] vb2: Add support for non monotonic timestamps" Signed-off-by:

Register both buses 0 and 1 via I2C API. For now, bus 0 is used only by eeprom on all known devices. Later patches will be needed if this changes in the future. Signed-off-by: -

Prepare to register a separate bus for the second bus. For now, just add a new field. A latter patch will add the bits to make it work. This patch was generated by this script: perl -e 'while (<>) { if (s/EM2874_I2C_SECONDARY_BUS_SELECT.*\n//) { printf "\t\t.def_i2c_bus = 1,\n"; $found = 1; print $_ } else { if ($found) { s/^\s+// }; $found = 0; print $_; } }' \ drivers/media/usb/em28xx/em28xx-cards.c >a && mv a drivers/media/usb/em28xx/em28xx-cards.c Signed-off-by: -

Newer em28xx devices have 2 buses. Change the logic to allow using both buses. This patch was generated by this small script: for i in drivers/media/usb/em28xx/*.c; do sed 's,->i2c_adap,->i2c_adap[dev->def_i2c_bus],g;s,->i2c_client,->i2c_client[dev->def_i2c_bus],' done Of course, em28xx.h needed manual edit.

Since commit 7543f344 ("[media] m920x: factor out a m920x_write_seq() function") building m920x.o triggers this GCC warning: drivers/media/usb/dvb-usb/m920x.c: In function ‘m920x_probe’: drivers/media/usb/dvb-usb/m920x.c:91:6: warning: ‘ret’ may be used uninitialized in this function [-Wuninitialized] This warning is caused by m920x_write_seq(), which is apparently inlined into m920x_probe(). It is clear why GCC thinks 'ret' may be used uninitialized. But in practice the first seq->address will always be non-zero when this function is called. That means we can change the while()-do{} loop into a do{}-while() loop. And that suffices to make GCC see that 'ret' will not be used uninitialized. Signed-off-by:

Thanks for the response, I have done as you suggested. Below is an updated patch for the OTG102 device against http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/cx231xx, kernel version 3.8. With further testing it appears the extra clauses in cx231xx-cards.c were not necessary (in static in cx231xx_init_dev and static int cx231xx_usb_probe), so those have been also been removed.

Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Similarly probe() methods should not be marked __init unless platform_driver_probe() is used. Signed-off-by:
