For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
