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.

35fa673e0e sunxi: phy: Add USB PHY support for Allwinner H6
The USB PHY used in the Allwinner H6 SoC has some pecularities (as usual),
which require a small addition to the USB PHY driver:
In this case the second PHY is PHY3, not PHY1, so we need to skip number
1 and 2 in the code. Just use the respective code from Linux for that.

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.

4b8cb84327 phy: marvell: Support changing SERDES map in board file
This adds a weak definition of comphy_update_map to comphy_core,
which does nothing. If this function is defined elsewhere, for example
in board file, the board file can change some parameters of SERDES
configuration.

This is needed on Turris Mox, where the SERDES speed on lane 1 has to
be set differently when SFP module is connected and when Topaz Switch
module is connected.

This is a temporary solution. When the comphy driver for armada-3720
will be added to the kernel, the comphy driver in u-boot shall also be
updated and this should be done differently then.

0bfcb47aa0 phy: sun4i-usb: Call phy_passby even for PHY#0
On newer Allwinner SoC, there is a pair of EHCI/OHCI USB hosts
for OTG host mode. USB PHY passby must be configured for its
corresponding PHY. so we can call for PHY#0. on the other hand
in past usb-phy code the same thing can be restricted for
Lower SoC's, other than H3/H5/A64.

Now there is no need to restrict usb passby since the phy driver
is DT enabled, and the respective phy calls will trigger based
DT information initiated by the drivers.

a1b2faed7c phy: Be able to get phy from PHY provider
In case of phy are provided from a PHY provider nodes as following:

usbphyc: usb-phy@5a006000 {
	compatible = "st,stm32mp1-usbphyc";
	reg = <0x5a006000 0x1000>;
	clocks = <&rcc_clk USBPHY_K>;
	resets = <&rcc_rst USBPHY_R>;
	#address-cells = <1>;
	#size-cells = <0>;

	usbphyc_port0: usb-phy@0 {
		reg = <0>;
		phy-supply = <&vdd_usb>;
		vdda1v1-supply = <&reg11>;
		vdda1v8-supply = <&reg18>
		#phy-cells = <0>;
	};

	usbphyc_port1: usb-phy@1 {
		reg = <1>;
		phy-supply = <&vdd_usb>;
		vdda1v1-supply = <&reg11>;
		vdda1v8-supply = <&reg18>
		#phy-cells = <1>;
	};
};

and PHY are called as following:

usbh_ehci: usbh-ehci@5800d000 {
	compatible = "generic-ehci";
	reg = <0x5800d000 0x1000>;
	clocks = <&rcc_clk USBH>;
	resets = <&rcc_rst USBH_R>;
	interrupts = <GIC_SPI 75 IRQ_TYPE_NONE>;
	companion = <&usbh_ohci>;
	phys = <&usbphyc_port0>;
	phy-names = "usb";
	status = "okay";
};

generic_phy_get_by_index() must be updated to first look for
PHY phandle as previously and in case of error looks for PHY
provider by finding the parent's current node which is the PHY
provider.
args (ofnode_phandle_args struct) must also be updated by inserting
the phy index into the PHY provider as args[0].
