This allows drivers to vmap contiguous dma buffers so they can inspect the buffer contents with the CPU. This will be needed for the CODA driver's JPEG handling. On CODA960, the header parsing has to be done on the CPU. The hardware modules can only process the entropy coded segment after all registers and tables are set up. Signed-off-by:

During the media summit meeting in Edinburgh it was decided to move this driver to staging as the first step to removing it altogether. Most webcams covered by this driver are now supported by gspca. Nobody has the hardware or is willing to convert the remaining devices to gspca. This driver needs a major overhaul to have it conform to the latest frameworks and compliancy tests. Without hardware, however, this is next to impossible. Given the fact that this driver seems to be pretty much unused (it has been removed from Fedora several versions ago and nobody complained about that), we decided to drop this driver. Signed-off-by:

Currently gspca selects the first ISOC input endpoint as the input transfer endpoint, however some devices can provide streams on endpoints different then the first one, so some subdrivers (e.g. gspca_kinect) may want to select a specific endpoint to use as a transfer endpoint. Add an xfer_ep field to struct gspca_dev, and change alt_xfer() so that it accepts a parameter which represents a specific endpoint address to look for. If a subdriver wants to specify a value for gspca_dev->xfer_ep it can do that in its sd_config() callback. Signed-off-by:

While this device doesn't have a scaler (or have it disabled), the screen dimentions are a function of the standard. Ok, right now, only 480 lines standards are implemented, although it supports other ones. Yet, let's calculate the size, to make easier to add more standards latter. Signed-off-by: -

It seems that there's a bug at au0828 hardware/firmware related to alternate setting: when the device is already at alt 5, a further call causes the URBs to receive -ESHUTDOWN. I found two different encarnations of this issue: 1) at qv4l2, it fails the second time we try to open the video screen; 2) at xawtv, when audio underrun occurs, with is very frequent, at least on my test machine. The fix is simple: just check if alt=5 before calling set_usb_interface(). Cc: stable@vger.kernel.org Signed-off-by: -

There are several issues on the current code: 1) msleep(1) is actually equivalent to msleep(10); 2) au8522_video_set() will set reg 0xa4 to the proper value for SIF, CVBS or S-Video. No need to force it to CVBS; 3) Let's not hardcode 0x9d for CBS on audio_set. Signed-off-by: -

setup_decoder_defaults() doesn't really care about the input port. All it needs to know is if the input port is s-video or not. As the caller function already knows that, just pass a boolean instead. Signed-off-by: -

Let's set the the audio routing also at stream start. With this change, we don't risk enabling the analog demux while not streaming, reducing the risk of interfering with a DVB demux that might be happening. Signed-off-by: -

The same demod is used on both analog and digital mode. We should not let the commands for analog mode to happen while the device is in digital mode. So, monitor it via streamon. Signed-off-by: -

The input mode is used not only inside the setup_decoder_defaults() but also at au8522_*_mode routines. So, move it one level up. As an advantage, we can now group the function that sets the input into just one. Signed-off-by: -

The platform data is a single word, so simply copy it into the device's private data structure than keeping a copy of the pointer. This will make changing to device-tree binding easier as it is one allocation instead of two. Signed-off-by:

devm_kzalloc() allocations are freed when the device is unbound. But if a certain path fails and the allocated memory cannot be used anyway it is better to free it explicitly immediately. This patch does exactly this if asynchronous group probing in scan_async_group() fails after memory has been allocated. Signed-off-by:

Calibrate the signal strength to dB. For this callibration, I used adapter 0 (antenna 1), connected via a normal cable to a DTF-2111 generator. The same cabling and RF generator connected to adapter 1 (antenna 2) has a difference of +3dBm (signal was stronger there). Yet, changing the RF for a difference of, let's say, 6dB reflected on a 6dB difference at the measured signal, with is good. So, the signal strengh can indeed be used to measure the antenna gain, if the antenna is repositioned. It is not precise to measure the absolute dBm value, however. Signed-off-by: -

Adds DVBv5 stats support. For now, just mimic whatever dib8000 does, as they're very similar, with regards to statistics. However, dib7000p_get_time_us() likely require some adjustments, as I didn't actually reviewed the formula for it to work with DVB-T. Still, better than nothing, as latter patches can improve it. This patch also doesn't show the signal strength in dB yet. The code is already there, but it requires to be callibrated. A latter patch will do the calibration. It seems that this patch is also a bug fix: Before this patch, the frontend were not tuning with some userspace tools. I suspect that dib7000p firmware or hardware internally expects that the statistics to be collected, in order for it to work. With this patch, the DVB core will always retrive statistics, even if userspace doesn't request. So, it makes the device work on all tested apps. Signed-off-by:
