If the partner is not PD capable, we can not use a power role set request to swap roles. Use the data role set request instead. Also, if a partner is not PD capable, it does not really make sense to send a PD message to trigger a role swap. On top of that, we should really wait for the attempted role change to complete. Otherwise, it may well be that user space requests another role change immediately afterwards which will fail because the port is not yet in ready state. Trigger the role swap from data role change requests and introduce new state PORT_RESET and use it to solve the problem. This new state is mostly identical to ERROR_RECOVERY, only it does not cause a pending role change to fail. Use this new state also when initializing the driver. Rename ERROR_RECOVERY_WAIT_OFF to PORT_RESET_WAIT_OFF to better reflect its new meaning.

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.
