Add support for Synopsys DWC3 core, with only BULK endpoints supported at the moment, as well as an initial vendor quirks system. Signed-off-by: Josuah Demangeon <me@josuah.net>
The udc_dwc3_enable() APIs allocates a buffer EP0. This causes an assertion fail when in a disable() -> enable() cycle. Hence, free this buffer when udc_dwc3_disable() is called. Signed-off-by: Amneesh Singh <amneesh@ti.com>
Reset the event buffer pointer to 0 in the enable() API. This resets the pointer in case of a disable() -> enable() cycle. Signed-off-by: Amneesh Singh <amneesh@ti.com>
Add TI vendor specific controller configurations, that are configured as part of the quirk subsystem of the Synopsys DWC3 controller. This involves two separate vendor regions "usbss" (USB subsystem) and "phy" (PHY configuration). Signed-off-by: Amneesh Singh <amneesh@ti.com>
Add node for the UDC device present on the board. This uses the Synopsys DWC3 controller with a TI specific wrapper for vendor specific configuration. This additionally requires some syscon configuration in the wakeup MMR region - hence, add that node as well. Signed-off-by: Amneesh Singh <amneesh@ti.com>
