In PTN5110 design, DisableSourceVBUS command also disables the sink enable signal because the EN_SNK can be used to source higher voltage, and, there is only one TCPC command to disable sourcing voltage without telling whether to disable 5V or the high voltage, and to keep the design simple they designed the PTN5110 to disable both. with this fact, we use the flag drive_vbus to check if the source vbus enable was issued, if yes we then do vbus source disable, in dead battery case, we never did vbus source enable, so will not issue vbus source disable command.

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.
