afef20585a phy: dphy: Add configuration helpers
The MIPI D-PHY spec defines default values and boundaries for most of the
parameters it defines. Introduce helpers to help drivers get meaningful
values based on their current parameters, and validate the boundaries of
these parameters if needed.

These helpers and header are taken from Linux commit 9123e3a74ec7 ("Linux 5.9-rc1").

66d9427403 phy: meson-gxl: remove invalid USB3 PHY driver
The registers which are managed by the meson-gxl-usb3 PHY driver are
actually "USB control" registers (which are "glue" registers which
manage OTG detection and routing of the OTG capable port between the
DWC2 peripheral-only controller and the DWC3 host-only controller).

Drop the meson-gxl-usb3 PHY driver now that the dwc3-meson-gxl-usb
driver supports the USB control registers on GXL and GXM SoCs (these
were previously managed by the meson-gxl-usb3 PHY driver).

888e1caeae phy: add support for AM654x SERDES
Add a new SERDES driver for TI's AM654x SoC which configures
the SERDES only for PCIe. Support fo USB3 can be added later.

SERDES in am654x has three input clocks (left input, external
reference clock and right input) and two output clocks (left
output and right output) in addition to a PLL mux clock which
the SERDES uses for Clock Multiplier Unit (CMU refclock).

The PLL mux clock can select from one of the three input
clocks. The right output can select between left input and
external reference clock while the left output can select
between the right input and external reference clock.

The driver has support to select PLL mux and left/right output
mux as specified in device tree.

277d9167cb phy: meson: add Amlogic G12A USB2 and USB3+PCIE PHY drivers
This adds support for the USB PHYs found in the Amlogic G12A SoC Family.

The USB2 PHY supports Host and/or Peripheral mode, depending on it's position.
The first PHY is only used as Host, but the second supports Dual modes
defined by the USB Control Glue HW in front of the USB Controllers.

The second driver supports USB3 Host mode or PCIE 2.0 mode, depending on
the layout of the board.
Selection is done by the #phy-cells, making the mode static and exclusive.

d7d7606c7e phy: Add USB PHY driver for the MT76x8 (7628/7688) SoC
This driver is derived from this Linux driver:
linux/drivers/phy/ralink/phy-ralink-usb.c

The driver sets up power and host mode, but also needs to configure PHY
registers for the MT7628 and MT7688.

I removed the reset controller handling for the USB host and device, as
it does not seem to be necessary right now. The soft reset bits for both
devices are enabled by default and testing has shown (with hackish
reset handling added), that USB related commands work identical with
or without the reset handling.

Please note that the resulting USB support is tested only very minimal.
I was able to detect one of my 3 currently available USB sticks.
Perhaps some further work is needed to fully support the EHCI controller
integrated in the MT76x8 SoC.

83d290c56f 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.
