The driver started a kthread to poll the DMA buffers soon after probing, which relsuleted in 1000/sec sleeps and wakeups of the thread doing nothing useful until someone started feeding. This patch changes the creation and destruction of the kthread depending on the number of users. Signed-off-by:

There are couple places where we check unsigned values for negative. I changed ->gpin_nr to signed because in gpio_ir_recv_probe() we do: if (pdata->gpio_nr < 0) return -EINVAL; I also change gval to a signed int in gpio_ir_recv_irq() because that's the type that gpio_get_value_cansleep() returns and we test for negative returns.

Support for m88rs2000 chip used in lmedm04 driver. Note there are still lock problems. Slow channel change due to the large block of registers sent in set_frontend. Version 2 differences. Front end is completely shut down when in sleep mode. This allow user to regain control of device. Kaffeine scan problem solved by removing register calls from get_frontend. Kaffeine seems to call get_frontend when updating signal data. This can happen in the middle of a tune stalling the driver. Change calculations to those in the DS3000 driver. Signed-off-by:

Ryley and me tested several eLNA configuration values with both a rooftop and a portable antenna. Ryley fuond out that the best value for his Elgato stick is indeed the current default value 0xC0. Instead, my stick is not capable of tuning VHF channels with 0xC0. With 0x80, VHF works but the tuner sensitivity with the portable antenna is poor. Instead, the value 0xA0 works with VHF and also gives good performance with both the rooftop and the portable antenna. So we concluded that devices built on the reference design work best with 0xA0, while custom designs (Elgato, PCTV) seem to require 0xC0. I also removed the unused parameter "minor" in struct as102_dev_t. Signed-off-by:

This patch fixes a regression in kernel 3.3 due to this patch: http://patchwork.linuxtv.org/patch/8332/ That patch changes "#pragma pack(1)" with "__packed" attributes, but it is not complete. In fact, in the as102 driver there are a lot of structs/unions defined inside other structs/unions. When the "__packed" attribute is applied only on the external struct, it will not affect the internal struct definitions. So the regression is fixed by specifiying the "__packed" attribute also on the internal structs. This patch should go into 3.3, as it fixes a regression introduced in the new kernel version.

In cx231xx_v4l2_close() there are two calls to cx231xx_release_resources(dev) followed by kfree(dev). That is a problem since cx231xx_release_resources() already kfree()'s its argument, so we end up doing a double free. Easily resolved by just removing the redundant kfree() calls after the calls to cx231xx_release_resources(). I also changed the 'dev = NULL' assignments (which are rather pointless since 'dev' is about to go out of scope), to 'fh->dev = NULL' since it looks to me that that is what was actually intended. And I removed the 'dev = NULL' assignment at the end of cx231xx_release_resources() since it is pointless. Signed-off-by:

Remove delays added for STV0288 frontend. This patch significantly speeds up channel change and scan. It requires patch 10161-STV0288 increase delay between carrier search. Signed-off-by:
-
Malcolm Priestley authored
The current delay of 30uS is too short to recover any carrier. In the lmedm04 driver delays were added to overcome carrier lock problems. The typical delay was 30mS (2 x 15ms register write 0x2c and read 0x24). Other drivers that use STV0288 don't appear to have any delay are likely to have also suffered this problem. Signed-off-by:

Laurent Pinchart authored
Drivers implementing custom ioctls need to handle 32-bit/64-bit compatibility themselves. Provide them with a way to do so. To avoid circular module dependencies, merge the v4l2-compat-ioctl32 module into videodev. There is no point in keeping them separate, as the v4l2_compat_ioctl32() function is required by videodev if CONFIG_COMPAT is set anyway. Signed-off-by:

Fix HW seek in TEA575x to work properly: - a delay must be present after search start and before first register read or the seek does weird things - when the search stops, the new frequency is not available immediately, we must wait until it appears in the register (fortunately, we can clear the frequency bits when starting the search as it starts at the frequency currently set, not from the value written) - sometimes, seek remains on the current frequency (or moves only a little), so repeat it until it moves by at least 50 kHz Signed-off-by:

The tea575x-tuner module has been updated to use the latest V4L2 framework functionality. This also required changes in the drivers that rely on it. The tea575x changes are: - The drivers must provide a v4l2_device struct to the tea module. - The radio_nr module parameter must be part of the actual radio driver, and not of the tea module. - Changed the frequency range to the normal 76-108 MHz range instead of 50-150. - Add hardware frequency seek support. - Fix broken rxsubchans/audmode handling. - The application can now select between stereo and mono. - Support polling for control events. - Add V4L2 priority handling. And radio-sf16fmr2.c now uses the isa bus kernel framework. Signed-off-by:
