Some em28xx devices use the PCM IN AC 97 PIN for digital audio. However, currently, the PCM IN selection is not set by the driver. This patch allows specifying the PCM IN expected output, via board description table. Signed-off-by: -

The zoran driver does a module_get/put of THIS_MODULE on device open/close. This isn't necessary as the kernel does this automatically. Clean up the failure path of zoran_open() somewhat. Make the dprintk()s on open/close a higher debug level and make the user count printed take the current open/close into account. Signed-off-by:

The driver should only use the kernel mapped io address, zr36057_mem, and not the PCI bus address, zr36057_adr. Since the latter is only printed out once, there is no need to save it in the driver data structure. There was some old code that looked like it was for the Alpha architecture which would use the PCI bus address. It probably no longer applies to modern kernels. Signed-off-by:

Instead of using custom code, just let the device layer look it up for us from the pci device table. This requires extending the pci device table to list each known card, plus a catch-all entry for the cards that don't have sub-system vendor/device data. Improve some of the info and error messages too. Signed-off-by:

Trent Piepho authored
The driver was keeping a global array with an entry for each zoran device probed. It was a leftover from when the driver didn't dynamically allocate the driver data for each device. There was only one use left, in the video device's ->open() method, looking up the struct zoran for the opened device from the minor number. This can be done better with video_get_drvdata(). Since zoran_num is now only used in the pci driver's ->probe() method, it doesn't need to be an atomic_t and be static. There is a race if multiple zoran cards could be probed at the same time, but currently the probe method for a given driver is single threaded. Signed-off-by:

When initializing a module parameter that is a per-card array, use "{ [0 ... (BUZ_MAX-1)] = -1 }" instead of "{ -1, -1, -1, -1 }". This way all of the entries will be correctly set to -1 if someone changes BUZ_MAX to a value other than 4. Adjust some of the parameter help text too. Signed-off-by: -

When enabling a shared IRQ line, then saa7134_irq handler could be invoked before the driver had completely set up internal structures, due to a shared interrupt line firing. Clear the saa7134 interrupt status reg, before requesting the irq line, so that stale IRQ status isn't processed before the internal structures are set up. Marcin Slusarz recently brought this Oops to the attention of the v4l-dvb lists and provided an initial analysis by investigating reports found here: http://kerneloops.org/guilty.php?guilty=mute_input_7133&version=2.6.27-release&start=1802240&end=1835007&class=oopsReported-by:

Analog support for HVR-1250 has not been completed, but does exist for the HVR-1800. Since both cards use the same driver, it tries to create the analog dev for both devices, which is not possible. This causes a NULL error to show up in video_open and mpeg_open. -Mark Iterations through the cx23885_devlist must check for NULL pointers as some supported devices only have DVB support at the moment. Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800 installed. -Andy Reported-by:

If Hauppauge eeprom is corrupted, the driver returns tuner = 0, instead of TUNER_ABSENT. This makes the drivers to initialize tuner, instead of handling the manual parameter. Since the tuner core rejects that a tuner to have their type changed, this breaks the manual tuner override. Signed-off-by: -

Changeset 60b4bde4 removed an unused struct on zoran driver, when compiled with "Y". However, as pointed by Jean Delvare <khali@linux-fr.org>, this is neeeded when the driver is compiled as a module, since udev relies on it to auto-load the module. Signed-off-by:

Concurrent access to a single DVB CA 50221 interface slot is generally discouraged. The underlying drivers (budget-av, budget-ci) do not implement proper locking and thus two transactions could (and do) interfere with on another. This fixes the following problems seen by others and myself: - sudden i/o errors when writing to the ci device which usually would result in an undefined state of the hw and require a software restart - errors about the CAM trying to send a buffer larger than the agreed size usually also resulting in an undefined state of the hw Due the to design of the DVB CA 50221 driver, implementing the locks in the underlying drivers would not be enough and still leave some race conditions, even though they were harder to trigger.

In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path. Signed-off-by:

This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders. This controller does not integrate the root hub, so this driver also fakes one-port hub. External hub is required to support more than one device. Signed-off-by:
