Hi Luis, The drivers that currently use regulators are mostly the ones at drivers/media/platform, plus the corresponding I2C drivers for their webcam sensors, under drivers/media/i2c. I think that there's one exception though: em28xx. This driver can use some sensor drivers, as it supports a few webcams. This is one of the most used USB media driver, as there are lots of USB supported on it, supporting 4 types of devices on it: analog TV, capture card, digital TV and webcam. The webcam part of em28xx is not that relevant, as there are very few models using it. However, currently, it is not possible to just disable webcam support. It shouldn't be hard to make webcam support optional on it, as it has already sub-drivers for V4L2, DVB, ALSA and remote controller. One additional driver for webcam, that could be disabled at the backport tree shouldn't be hard to do. If you want it, patches are welcome. > Here's a list of media drivers I know SUSE does support, in case that > helps.
