Hi Balbi, This series adds usb support to am335x SoC's found on boards like Beagle Bone. Here only first instance is supported, as currently multiple phy's of same type is not supported (am335x has two USB2 phy's). This series is based on your musb branch, (HEAD - 2f77116 usb: musb: remove hand-crafted id handling) and is made over my series, (usb: musb: dsps: fixes for -rc) and has been tested on Beagle Bone by ethernet gadget. First two may qualify as -rc material, with these two it is actually possible to get USB working assuming bootloader leaves phy enabled and provides Kernel with DT blob. Last one configures control module to enable bultin phy. Proper solution is to make use of control module driver, but it is not expected to be ready soon and this would block USB support for am335x. Here dsps wrapper driver is provided with control module register physical address. Even though this a hack, there is no other option left till control module driver is ready. As of now only am335x is using dsps wrapper, and so driver is made aware of am335x control module physical address. Please note that this is a temporary arrangment till omap control module driver is available. Other options are providing control module register space as memory resource via DT or using omap hwmod. DT approach has been rejected by Rob Herring, while resources are being moved from hwmod to DT. And both of the above approaches require that control module registers be configured in wrapper driver itself requring a quirk in driver as well as DT or hwmod.
