When loading the firmware, complete each chunk by sending an I2C flush command to the frontend. Some devices like the tm6000 seem to require this to properly flush the I2C buffers. The current code in tm6000 executes the flush command once after each I2C transfer, which slows down the firmware loading especially when loading large BASE type images. Signed-off-by:

The ccdc block in the omap3isp produces events whenever it starts receiving a new frame. A private HS_VS event was used for this previously. Now, the generic V4L2_EVENT_FRAME_SYNC event is being used for the purpose. This patch also provides the frame sequence number to user space. Signed-off-by:

This patch reduces the number of available choices for the notch filter type control so that the standard-specific filter types cannot be selected. It is now limited to being either 0 (4xFsc, the default) or 1 (square pixel optimized). The patch also removes the initialization of this control from cx88_reset(), since that is already done by init_controls(), which is called by cx8800_initdev(). Signed-off-by:

Fronted and Tuner Driver for ITE IT913x Series with inital support for IT9137 integrated demodulator and tuner device. The driver is loosely based on AF9035 series. However, support is not intended for this device specificity. The IT9137 tuner has been tested on UHF bands, but VHF has only been simulated. Possible TODO the tuner sections may be separated from the main driver. All future devices should use the it913x_fe_script_loader for other tuner devices. Signed-off-by:

Siano modules already had sms_dbg flag which is a module parameter which sets the debug mode so module prints messages to dmesg for debugging. The variable was static therefore apply only to the file which defines the module. In modules as smsmdtv.ko that contain a few files, the debug flag applied only for functions in that main file. flag was changed to be non-static and therefore can be accessed by all module files (although it is still not exported out of the module).

Rather than dumping out hex values, lets print the actual calculated frequency and period the hardware has been configured for. After this [ 2643.276215] mceusb 3-1:1.0: tx data: 9f 07 (length=2) [ 2643.276218] mceusb 3-1:1.0: Get carrier mode and freq [ 2643.277206] mceusb 3-1:1.0: rx data: 9f 06 01 42 (length=4) [ 2643.277209] mceusb 3-1:1.0: Got carrier of 37037 Hz (period 27us) Matches up perfectly with the table in Microsoft's docs. Of course, I've noticed on one of my devices that the MS-recommended default value of 1 for carrier pre-scaler and 66 for carrier period was butchered, and instead of converting 66 to hex (0x42 like above), they put in 0x66, so the hardware reports a default carrier of 24390Hz. Fortunately, I guess, this particular device is rx-only, but I wouldn't put it past other hw to screw up here too. Signed-off-by:

According to the specs, you can read the number of tx ports, number of rx sensors, which tx ports have cables plugged into them, and which rx sensors are active. In practice, most of my devices do seem to report sane values for tx ports and rx sensors (but not all -- one without any tx ports reports having them), and most report the active sensor correctly, but only one of eight reports cabled tx ports correctly. So for the most part, this is just for informational purposes. Signed-off-by:

Supposedly, there are essentially three different classes of devices that are compatible with Microsoft's specs. First are the "legacy" devices, which are built using Microsoft-provided hardware specs and firmware. Second are "emulator" devices, which are built using custom hardware and firmware, written to emulate Microsoft's firmware. Third are "port" devices, which have their own device driver and firmware, which provides compatible data to higher levels of the stack. >From what I can tell, things like nuvoton-cir and fintek-cir are essentially "port" devices -- their raw IR buffer format is very similar to that of the mceusb devices. Now, within the mceusb driver, we have three different "generations", which at first, seemed like maybe they mapped to emulator versions. Unfortuantely, every single device I have responds "illegal command" to the query to get firmware emulator version from the hardware, which means they're either all emulator version 1, or they're legacy devices, and our different "generations" aren't at all related here. Though in theory, its possible the gen1 devices are "legacy" devices and the rest are emulator v1. There are some useful features of the v2 interface I was hoping to play with, but alas...

I was recently pointed to the document titled Windows-Media-Center-RC-IR-Collection-Green-Button-Specification-03-08-2011-V2.pdf which as of this writing, is publicly available from download.microsoft.com. It covers a LOT of the gaps in the mceusb driver, which to this point, was written almost entirely by reverse-engineering. First up, I'm updating the defines for all the MCE commands and responses to match their names in the spec. More to come... Signed-off-by:

Hello, When migrating from Slackware 13.1 to 13.37 (kernel 2.6.33.x to 2.6.37.6), there was some sort of regression with the external webcam installed at the notebook (0x45:6128, SN9C325+OM6802). In the version 2.6.37.6, the images got *very* dark, making the webcam almost unusable, unless if used with direct sunlight. Tracing back what happened, I concluded that changeset 0e4d413a caused some sort of odd effects - including this - to this specific model. Signed-off-by:

If the bus has been reset on resume, set the alternate setting to 0. This should be the default value, but some devices crash or otherwise misbehave if they don't receive a SET_INTERFACE request before any other video control request.

This device is not using the proper demod IF. Instead of using the IF macro, it is specifying a IF frequency. This doesn't work, as xc3028 needs to load an specific SCODE for the tuner. In this case, there's no IF table for 5 MHz. Cc: stable@kernel.org Signed-off-by: -

Potentially the adp1653_init_controls could return an error. In our case the error was ignored, meanwhile it means incorrect initialization of V4L2 controls. Additionally we have to free control handler structures in case of apd1653_init_controls or media_entity_init failure. Signed-off-by:
