pinmux: Add API for pinmux driver This provides the API to manipulte the pin muxing, where a single pin may provide different functions depending on settings. [DL: changed commit message.] Change-Id: Ifd161137c062dff184024b5aa34737604911d09c Signed-off-by: Dan Kalowsky <daniel.kalowsky@intel.com> Signed-off-by: Daniel Leung <daniel.leung@intel.com>

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

pinmux: Expand the pin function/mode parameter size The pinmux API was modified to expand the meaning of the 'func' argument to allow it to represent more than a pre-configured function. This was done to reasonably accommodate a larger range of pin configuration options offered by other MCUs, such as the Freescale K64 (up to 8 pin functions, plus interrupt, pullup/down, drive strength, open-drain, slew rate, etc.). This allows bit fields to be used to define various settings. Change-Id: I2b216b822c6bae7133eed01c8c3339bb47b6c5db Signed-off-by: Jeff Blais <jeff.blais@windriver.com>
