The ULPI specification defines a standard set 2362306a36Sopenharmony_ci of registers that can be used to detect the vendor and product which 2462306a36Sopenharmony_ci allows ULPI to be handled as a bus. This module is the driver for that 2562306a36Sopenharmony_ci bus. 2662306a36Sopenharmony_ci 2762306a36Sopenharmony_ci The ULPI interfaces (the buses) are registered by the drivers for USB 2862306a36Sopenharmony_ci controllers which support ULPI register access and have ULPI PHY 2962306a36Sopenharmony_ci attached to them. The ULPI PHY drivers themselves are normal PHY 3062306a36Sopenharmony_ci drivers. 3162306a36Sopenharmony_ci 3262306a36Sopenharmony_ci ULPI PHYs provide often functions such as ADP sensing/probing (OTG 3362306a36Sopenharmony_ci protocol) and USB charger detection. 3462306a36Sopenharmony_ci 3562306a36Sopenharmony_ci To compile this driver as a module, choose M here: the module will 3662306a36Sopenharmony_ci be called ulpi. 3762306a36Sopenharmony_ci 3862306a36Sopenharmony_ciconfig USB_CONN_GPIO 3962306a36Sopenharmony_ci tristate "USB GPIO Based Connection Detection Driver" 4062306a36Sopenharmony_ci depends on GPIOLIB 4162306a36Sopenharmony_ci select USB_ROLE_SWITCH 4262306a36Sopenharmony_ci select POWER_SUPPLY 4362306a36Sopenharmony_ci help 4462306a36Sopenharmony_ci The driver supports USB role switch between host and device via GPIO 4562306a36Sopenharmony_ci based USB cable detection, used typically if an input GPIO is used 4662306a36Sopenharmony_ci to detect USB ID pin, and another input GPIO may be also used to detect 4762306a36Sopenharmony_ci Vbus pin at the same time, it also can be used to enable/disable 4862306a36Sopenharmony_ci device if an input GPIO is only used to detect Vbus pin. 4962306a36Sopenharmony_ci 5062306a36Sopenharmony_ci To compile the driver as a module, choose M here: the module will 5162306a36Sopenharmony_ci be called usb-conn-gpio.ko 52
