The Motorola CPCAP USB PHY contains the hardware state machine used for USB cable detection. Besides distinguishing USB peripheral and host connections, it can also detect dedicated charging ports (DCP). This series extends the CPCAP USB PHY driver to detect DCP connections and export the detected cable state through the Extcon framework. It also makes the idle UART mode optional, allowing the PHY to remain in its default USB detection configuration unless UART support is explicitly requested. The series updates the Device Tree binding for the optional charger detection interrupt and the optional "safe" pinctrl state. Corresponding mapphone Device Tree entries are added to describe the charger detection interrupt and enable the safe pinctrl state. The charger detection interrupt is not currently used by the driver. However, it is added to the binding and Device Tree because it describes a hardware capability of the CPCAP USB PHY. The series has been tested on Motorola Droid 4 hardware.
Due to mangled CC "--cc=linux-phy@lists.infradead.org" PHY list was not CCed to this series. Please fix it in the next version. - Mani -- மணிவண்ணன் சதாசிவம் -- linux-phy mailing list linux-phy@lists.infradead.org https://lists.infradead.org/mailman/listinfo/linux-phy
