From: Konstantin Porotchkin <kostap@marvell.com>
This series of patches adds a new PHY driver for supporting CP110 UTMI
PHY in Linux. Currently the functionality of USB ports connected to
this PHY depends on boot loader setup.
The new driver eliminates kernel configuration dependency from the boot
loader.
v3:
- rebase on top of Linux 5.12-rc2
- convert Armada 3700 UTMI PHY DT binding document to YAML schema
- create a separate DT binding for Armada CP11x UTMI PHY in YAML format
- change UTMI PHY port node names from "phy" to "usb-phy"
v2:
- extend the comment about reference clock
- fix driver probe function, add some prints
- move to usage of dr_mode from connected USB controller instead of
dedicated device tree property

From: Konstantin Porotchkin <kostap@marvell.com>
Add support for Marvell CP110 UTMI PHY driver allowing the USB2
port configuration independently from the boot loader setup.
The CP110/CP115 dies have 2 UTMI PHYs that could be connected
to two USB host controllers or to single USB device controller.
Since there is only one USB device controller on die, only one
of the UTMI PHYs could work in USB device mode.
The CONFIG_PHY_MVEBU_CP110_UTMI should be enabled for usage of
this driver.

-MVEBU A3700 UTMI PHY
---------------------
-
-USB2 UTMI+ PHY controllers can be found on the following Marvell MVEBU SoCs:
-* Armada 3700
-
-On Armada 3700, there are two USB controllers, one is compatible with the USB2
-and USB3 specifications and supports OTG. The other one is USB2 compliant and
-only supports host mode. Both of these controllers come with a slightly
-different UTMI PHY.
-
-Required Properties:
-
-- compatible: Should be one of:
- * "marvell,a3700-utmi-host-phy" for the PHY connected to
- the USB2 host-only controller.
- * "marvell,a3700-utmi-otg-phy" for the PHY connected to
- the USB3 and USB2 OTG capable controller.
-- reg: PHY IP register range.
-- marvell,usb-misc-reg: handle on the "USB miscellaneous registers" shared
- region covering registers related to both the host
- controller and the PHY.
-- #phy-cells: Standard property (Documentation: phy-bindings.txt) Should be 0.
-
-
-Example:
-
- usb2_utmi_host_phy: phy@5f000 {
- compatible = "marvell,armada-3700-utmi-host-phy";
- reg = <0x5f000 0x800>;
- marvell,usb-misc-reg = <&usb2_syscon>;
- #phy-cells = <0>;
- };
-
- usb2_syscon: system-controller@5f800 {
- compatible = "marvell,armada-3700-usb2-host-misc", "syscon";
- reg = <0x5f800 0x800>;
- };

-MVEBU A3700 UTMI PHY
---------------------
-
-USB2 UTMI+ PHY controllers can be found on the following Marvell MVEBU SoCs:
-* Armada 3700
-
-On Armada 3700, there are two USB controllers, one is compatible with the USB2
-and USB3 specifications and supports OTG. The other one is USB2 compliant and
-only supports host mode. Both of these controllers come with a slightly
-different UTMI PHY.
-
-Required Properties:
-
-- compatible: Should be one of:
- * "marvell,a3700-utmi-host-phy" for the PHY connected to
- the USB2 host-only controller.
- * "marvell,a3700-utmi-otg-phy" for the PHY connected to
- the USB3 and USB2 OTG capable controller.
-- reg: PHY IP register range.
-- marvell,usb-misc-reg: handle on the "USB miscellaneous registers" shared
- region covering registers related to both the host
- controller and the PHY.
-- #phy-cells: Standard property (Documentation: phy-bindings.txt) Should be 0.
-
-
-Example:
-
- usb2_utmi_host_phy: phy@5f000 {
- compatible = "marvell,armada-3700-utmi-host-phy";
- reg = <0x5f000 0x800>;
- marvell,usb-misc-reg = <&usb2_syscon>;
- #phy-cells = <0>;
- };
-
- usb2_syscon: system-controller@5f800 {
- compatible = "marvell,armada-3700-usb2-host-misc", "syscon";
- reg = <0x5f800 0x800>;
- };

Patch 4 and 5 applied on mvebu/dt64.
I've just modified the title to align with the other commits in
arch/arm64/boot/dts/marvell. They now begin by "arm64: dts: marvell:".
Thanks,
Gregory
