Hi Jean-Jacques, Marek,
The K2G platforms can use the generic DWC3 driver instead of relying on the keystone-xhci driver. Benefits are:
- moving toward DM
- brings USB gadget for free
- allows us to remove some code
Tested on:
- K2G EVM
I'm not sure if I shall wait for Marek's PR to Tom (preferred) or send new PR to Marek?
Marek what do you think?
Changes in v2:
- rebased on latest version of u-boot-usb/master
- use DM_USB_GADGET instead of DM_USB_DEV
Jean-Jacques Hiblot (6): usb: dwc3-generic: make it compatible with "ti,keystone-dwc3" board: ks2_evm: Enable the USB clocks if DM_USB is used ARM: dts: k2g-evm: enable USB0 and USB1 PHY: Add phy driver for the keystone USB PHY usb: host: replace xhci-keystone driver by the generic dwc3 driver configs: k2g_evm: Enable DFU on K2G EVM
