Thanks to work done by Broadcom explaining their USB 3.0 PHY details we know it's attached to the MDIO bus. Use this knowledge to update the binding: make it a subnode to the MDIO bus and rework way of specifying required registers. This will describe hardware more precisely and will allow to support (describe) more devices attached to the MDIO. While compatibility strings remain the same there isn't a direct conflict (compatibility breakage) for the binding. Originally it wasn't supposed to be used for MDIO subnode so this change should be safe unless some operating system was probing MDIO subnodes as standalone devices.

The USB 3.0 PHY modules of R-Car Gen3 SoCs have: - Spread spectrum clock (ssc). - Using USB 2.0 EXTAL clock instead of USB 3.0 clock. - Enabling VBUS detection for usb3.0 peripheral. So, this driver supports these features. Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

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.
