The bus-based I2C subsystem allocates the i2c_client struct. So if in order to be able to convert the tuner to the bus-based I2C API the embedded i2c_client struct must be removed from the tuner struct and replaced with a pointer. Signed-off-by:

The next patchset series will change i2c structs inside tuner. This patch avoids breaking bissect, by commenting the still unused tuner xc2028. Signed-off-by:

TUNER_PHILIPS_TDA8290 will autodetect a TDA8290 or a TDA8295, so we don't need this separate entry anymore. Signed-off-by:

Consolidate tda8290_attach() and tda8295_attach() into a single function, tda829x_attach(), which will detect chip combinations tda8290 or tda8295 with tda8275, tda8275a or tda18271. Signed-off-by:

The remove driver function expects that the client is still attached to the driver, so do the detach after calling remove(). Signed-off-by:

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. Signed-off-by:

Some devices do complicated tests whether the device can be probed or not. Add a legacy_probe function pointer to support that. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Add basic support for NXP TDA8295 analog demod and TDA18271 tuner silicon. TDA8295 + TDA8275a not yet tested. TDA8290 + TDA18271 not yet supported. Digital mode of TDA18271 not yet tested & needs more work. Signed-off-by:

Add analog tuning support to tda827x dvb_frontend tuner module. Convert tda8290 module back to native tuner interface. The tda8290 analog demodulator will be handled the same way as tda9887. The tuner.ko module (tuner-core) will pass commands to tda8290 via the tuner_operations interface. tda8290 will communicate with tda827x via the dvb_frontend interface, while passing a pointer to a private data structure.
