Jacob Dahl b986fb8ee5 {arm,xtensa}/otg: indent switch bodies per the coding standard.
nxstyle now checks case labels against their enclosing brace, and the
DWC2-derived OTG device drivers align every case label with the switch
brace itself, so any change that touches one of these files fails
checkpatch on hundreds of pre-existing lines.

Indent the switch bodies by two columns as the standard requires and
re-wrap the lines that this pushes past the width limit. Whitespace and
comment re-flow only; no code changes.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

Contributing

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
