SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

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.

usb: dwc3: Add disable u2mac linestate check quirk This patch adds a quirk to disable USB 2.0 MAC linestate check during HS transmit. Refer the dwc3 databook, we can use it for some special platforms if the linestate not reflect the expected line state(J) during transmission. When use this quirk, the controller implements a fixed 40-bit TxEndDelay after the packet is given on UTMI and ignores the linestate during the transmit of a token (during token-to-token and token-to-data IPGAP). On some rockchip platforms (e.g. rk3399), it requires to disable the u2mac linestate check to decrease the SSPLIT token to SETUP token inter-packet delay from 566ns to 466ns, and fix the issue that FS/LS devices not recognized if inserted through USB 3.0 HUB.
