2007-09-16Use correct error codes when chip is not recognized.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> If the chip isn't recognized, then the correct errors should be returned. The v4l2_i2c_attach() utility function will return 0 for all errors except -ENOMEM to provide proper compatibility support for the old I2C probing function.

2007-09-12v4l2: add support for bus-based I2C driversHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Two new headers were added: one for I2C drivers that are only used by V4L2 drivers converted to the new bus-based I2C API, and one that can be used by both converted and unconverted drivers (at the expense of some additional overhead). To support the legacy I2C API a helper function was added to v4l2-common.c. These headers take care of all the 'boilerplate' code that all V4L2 I2C drivers have in common and will automatically support the bus-based I2C API introduced in kernel 2.6.22.

2007-10-24tuner: add i2c_gate_ctrl function to struct analog_tuner_opsMichael Krufky
From: Michael Krufky <mkrufky@linuxtv.org> In some designs, the tuner silicon may be on an i2c bus behind an i2c gate, controlled by the analog demodulator. We already have a method to control such i2c gates when they are controlled by the digital demodulator, but in some hybrid designs, there may be an i2c gate controlled by each demodulator. For example, when in analog tuning mode, one would access the tuner by opening the i2c gate controlled by the analog demodulator, while when in digital tuning mode, one would access the tuner by opening the i2c gate controlled by the digital demodulator. We must add this callback function to analog_tuner_ops in order to handle such configurations.

From: Trent Piepho <xyzzy@speakeasy.org> cx23885 was still uses the old video-buf includes and code, which would only `work' if one happened to be compiling against a kernel that had the old headers.

2007-10-04videobuf: Remove references to old Kconfig option nameTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB. But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver. The reference in cx23885.h should just be removed, as the code there needs to be included if DVB is on or off. I do not think you can even compile the cx23885 driver without DVB. It's clearly just leftover from when the file was obvious copied from the cx88 driver (which is not mentioned in the copyright BTW). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
