From 6b7ebff00190649d2136b34f6feebc0dbe85bfdc Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Tue, 19 Nov 2019 13:56:20 +0530 Subject: usb: dwc3: Add phy interface for dwc3_uboot U-Boot has two different variants of dwc3 initializations, - with dm variant gadget, so the respective dm driver would call the dwc3_init in core. - with non-dm variant gadget, so the usage board file would call dwc3_uboot_init in core. The driver probe would handle all respective gadget properties including phy interface via phy_type property and then trigger dwc3_init for dm-variant gadgets. So, to support the phy interface for non-dm variant gadgets, the better option is dwc3_uboot_init since there is no dedicated controller for non-dm variant gadgets. This patch support for adding phy interface like 8/16-bit UTMI+ code for dwc3_uboot. This change used Linux phy.h enum list, to make proper code compatibility.
