There are two different encodings used for nec32: - The ir-nec-decoder.c decoder treats it as 32 bit msb first. - The img-ir decoder/encoder, winbond wakeup, dib0700, ir-ctl userspace, treat nec32 analogous to necx and nec: 4 bytes, each lsb first. So this format reverses the 4 bytes. There are arguments to be had for both formats, but we should not use different formats in different parts of the kernel. Selecting the second format introduces the least code churn. It does mean that the TiVo keymap needs updating. This change was submitted before as "18bc174 [media] media: rc: change 32bit NEC scancode format", which was reverted because it was unclear what scancode rc drivers produce. There are now more examples of drivers which produce nec32 in lsb format. The TiVo keymap is verified against the Nero Liquid TiVo remote. The keymap is not for the Tivo DVR remote, which uses rc-5.

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.
