2014-07-07[media] dib8000: improve the message that reports per-layer locksMauro Carvalho Chehab
The message is currently highly encoded: [70299.863521] DiB8000: Mpeg locks [ L0 : 0 | L1 : 1 | L2 : 0 ] And doesn't properly reflect that some problems might have happened. Instead, display it as: [75160.822321] DiB8000: Not all ISDB-T layers locked in 32 ms: Layer A NOT LOCKED, Layer B locked, Layer C not enabled In order to better reflect what's happening with layer locking.

2014-07-07[media] dib8000: use jifies instead of current_kernel_time()Mauro Carvalho Chehab
Instead of doing the tuning delays and timeouts using current_kernel_time(), use jiffies. That consumes less CPU cycles, and it is monotonic. Acked-By: Patrick Boettcher <pboettcher@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-07-07[media] dib0090: Fix the sleep time at the state machineMauro Carvalho Chehab

2014-07-07[media] dib8000: In auto-search, try first with partial reception enabledMauro Carvalho Chehab
TV broadcasters generally use partial reception. So, enable it by default in auto-search mode. The driver will latter detect if the transmission is on some other mode. Acked-By: Patrick Boettcher <pboettcher@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-07-07[media] dib8000: Fix: add missing 4K FFT modeMauro Carvalho Chehab

2014-07-07[media] dib8000: Fix handling of interleave bigger than 2Mauro Carvalho Chehab

2014-07-04[media] videobuf2-dma-contig: allow to vmap contiguous dma buffersPhilipp Zabel
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.

2014-07-04[media] sn9c102: remove deprecated driverHans Verkuil
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.

2014-07-04[media] gspca: provide a mechanism to select a specific transfer endpointAntonio Ospite
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.

While this device doesn't have a scaler (or have it disabled), the screen dimentions are a function of the standard.

2014-06-19[media] au0828: Only alt setting logic when neededMauro Carvalho Chehab
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: Mauro Carvalho Chehab <m.chehab@samsung.com>
