- Add generic GPIO driver for Cavium Octeon. At the moment pin definition is hardcoded but will be changed later with more flexible way to define them. 2011-12-28 05:57:03 +00:00			`/*-`
sys/mips: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-11-27 15:07:26 +00:00			`* SPDX-License-Identifier: BSD-2-Clause-FreeBSD`
