2016-09-16Merge branch 'driver-api' into doc/4.9Jonathan Corbet16-598/+734
This short series convers device-drivers.tmpl into the RST format, splits it up, and sets up the result under Documentation/driver-api/. For added fun, I've taken one top-level file (hsi.txt) and folded it into the document as a way of showing the direction I'm thinking I would like things to go. There is plenty more of this sort of work that could be done, to say the least - this is just a beginning! The formatted results can be seen at: http://static.lwn.net/kerneldoc/driver-api/index.html As part of the long-term task to turn Documentation/ into less of a horror movie, I'd like to collect documentation of the driver-specific API here. Arguably gpu/ and the media API stuff should eventually move here, though we can discuss the color of that particular shed some other day. Meanwhile, I'd appreciate comments on the general idea.

2016-09-09[media] v4l: rcar-fcp: Don't force users to check for disabled FCP supportLaurent Pinchart1-1/+1
The rcar_fcp_enable() function immediately returns successfully when the FCP device pointer is NULL to avoid forcing the users to check the FCP device manually before every call. However, the stub version of the function used when the FCP driver is disabled returns -ENOSYS unconditionally, resulting in a different API contract for the two versions of the function. As a user that requires FCP support will fail at probe time when calling rcar_fcp_get() if the FCP driver is disabled, the stub version of the rcar_fcp_enable() function will only be called with a NULL FCP device. We can thus return 0 unconditionally to align the behaviour with the normal version of the function.

The V4L2_PIX_FMT_SBGGR16 format is documented to contain samples of fewer than 16 bits. However, we do have specific definitions for smaller sample sizes.
