[PATCH] usb: dwc2: gadget: Fix GUSBCFG.USBTRDTIM value

2017-01-12 Thread Amelie Delaunay
USBTrdTim must be programmed to 0x5 when phy has a UTMI+ 16-bit wide interface or 0x9 when it has a 8-bit wide interface. GUSBCFG reset value (Value After Reset: 0x1400) sets USBTrdTim to 0x5. In case of 8-bit UTMI+, without clearing GUSBCFG.USBTRDTIM mask, USBTrdTim results in 0xD (0x5 | 0x9). Tha
