Some Motorola phones like droid 4 use a custom CPCAP PMIC that has a multiplexing USB PHY. This USB PHY can operate at least in four modes using pin multiplexing and two control GPIOS: - Pass through companion PHY for the SoC USB PHY - ULPI PHY for the SoC - Pass through USB for the modem - UART debug console for the SoC This patch adds support for droid 4 USB PHY and debug UART modes, support for other modes can be added later on as needed. Both peripheral and host mode are working for the USB. The host mode depends on the cpcap-charger driver for VBUS. VBUS and ID pin detection are done using cpcap-adc IIO ADC driver.

README
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.
