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").

a074667d52 Kconfig: Varios: Fix more SPL, TPL dependencies
Several options are presenting themselves on a various boards
where the options are clearly not used.  (ie, SPL/TPL options
when SPL or TPL are not defined)

This patch is not attempting to be a complete list of items, but
more like low hanging fruit.  In some instances, I wasn't sure
of DM was required, so I simply made them SPL or TPL.

This patch attempts to reduce some of the menuconfig noise
by defining dependencies so they don't appear when not used.

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.

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.
