The UVC specification requires frame descriptors indexes to range from 1 to the number of frame descriptors. At least some Hercules Dualpix Infinite webcams erroneously use non-continuous index ranges. Make the driver support them. Signed-off-by:

I have been informed by the manufacturer that the patch currently in the v4l tree to support the Genpix-CW3K version of the hardware will actually damage the firmware on recent units. As he seems to not want this hardware supported in Linux, and I do not know how to detect the difference between affected and not-affected units, I am requesting the immediate removal of support for this device. This patch removes a portion of the changeset dce7e08ed2b1 applied 2007-08-18 relating to this specific device. Adapted patch to not remove code, but to only to comment it out. Signed-off-by:

dibusb_i2c_xfer seems to do things very dangerous : it assumes that it get only write/read request or write request. That means that read can be understood as write. For example a program doing file = open("/dev/i2c-x", O_RDWR); ioctl(file, I2C_SLAVE, 0x50) read(file, data, 10) will corrupt the eeprom as it will be understood as a write.

This patch is reorganizing the frontend-attach mechanism in order to gain noise-less (superflous prints) deactivation of submodules. Credits go to Uwe Bugla for helping to clean and test the code. Signed-off-by:

The em28xx actually has a register that tells the driver what the maximum packet size is (based on a value programmed into the eeprom). Make use of that register instead of assuming a hardcoded value of 564 (since 564 is not correct for devices that do QAM such as the KWorld 340u). Note that for now the em2874 code isn't there, falling back to the 564 value, however this is not a problem since there are not any em2874 based devices in the current v4l-dvb tree). Thanks to Jarod Wilson for detecting the initial problem and figuring out that the isoc configuration was wrong for his device. Cc: Jarod Wilson <jarod@wilsonet.com> Signed-off-by:

According to the engineer at PCTV Systems, the xc5000 reset pin is supposed to be on GPIO12. However, despite three nights of effort, pulling that GPIO low didn't reset the xc5000. While pulling MO_SRST_IO low does reset the xc5000, this also resets in the s5h1409 being reset as well. This causes tuning to always fail since the internal state of the s5h1409 does not match the driver's state. Given that the only two conditions in which the driver performs a reset is during firmware load and powering down the chip, I am taking out the reset. We know that the chip is being reset when the cx88 comes online, and not being able to do power management for this board is better than not having any tuning at all. Problem discovered when implementing proper power management for the xc5000, which results in calls to the reset callback *after* s5h1409 is initialized.

Make sure the au0828 issues the command to power down the tuner when the user is done using analog support. Signed-off-by:

Instead of polling at 100ms intervals for register writes, poll at 5ms intervals. This is consistent with the xc5000 specification, and improves tuning time by up to 500 ms on devices that such as the au0828 which do not properly implement i2c clock stretching (since the five register writes that occur for a tuning request often do not complete immediately but do complete far before 100ms has gone by). The net amount of time we wait before timing out is unchanged (500ms). Signed-off-by:

Xceive has graciously allowed us to now freely redistribute the xc5000 firmware, which eliminates the need for users to manually extract the blob from the Hauppauge driver. Thanks to Brian Mathews <bmathews@xceive.com> for providing this code Signed-off-by:

Defer loading of the xc5000 firmware until it is actually needed. This helps on distros that have hald, which results in the device not being available for use for around ten seconds in cases where the i2c bus is slow (such as the HVR-950Q). Also, the firmware load isn't really useful since we immediately put the device to sleep afterward, which means a firmware reload will be required anyway. Signed-off-by:

Provide for the ability for a user to disable putting the tuner to sleep, in case he doesn't want to incur the cost of reloading the firmware when starting up his/her application. The module options are intentionally identical to xc3028. Signed-off-by:

Make it a little more obvious in the dmesg output what is going on during firmware upload. This is more important for boards like the HVR-950q that take nearly seven seconds to do the upload. Signed-off-by:

The xc5000 datasheet indicates that the reset pin only needs to be held low for 10ms. Reduce the value accordingly, which speeds up the firmware load time a bit. Signed-off-by:

Xceive got rid of the XREG_POWER_DOWN register in later firmware revisions. Their technical support informed me that the correct way to put the tuner to sleep is to pull the reset pin (but don't reload the firmware). Signed-off-by:

This switches to a new version of the xc5000 firmware, extracted from the latest Hauppauge driver. It includes the support for the XREG_BUSY register (a lack of which was causing tuning to take 3200ms instead of around 300ms). Signed-off-by:

Bring back the code that puts the xc5000 to sleep. For the Pinnacle 801e this results in power consumption at idle dropping from 325ma to 124ma. If there are *actually* any devices that don't work in this configuration, they should set dvb_frontend.ops.tuner_ops.sleep to NULL (per mkrufky's suggestion) Also, had to make sure we were making sure the firmware was loaded in the digital version of set_params, or else we end up get i2c errors if the device is asleep Signed-off-by:

This patch centralizes the i2c read functions, and eliminates pass-through function only called by one caller. Make reading of xc5000 registers an atomic i2c transaction in case we're on a multi-master bus. Signed-off-by:
