add support for PCIe and SATA, also add some new compatibles.
due to phy-mt65xx-usb.txt holds the bindings for all mediatek SoCs
with T-PHY controller, change the name to phy-mtk-tphy.txt to
reflect that.

-mt65xx USB3.0 PHY binding
---------------------------
-
-This binding describes a usb3.0 phy for mt65xx platforms of Medaitek SoC.
-
-Required properties (controller (parent) node):
- - compatible : should be one of
- "mediatek,mt2701-u3phy"
- "mediatek,mt2712-u3phy"
- "mediatek,mt8173-u3phy"
- - clocks : (deprecated, use port's clocks instead) a list of phandle +
- clock-specifier pairs, one for each entry in clock-names
- - clock-names : (deprecated, use port's one instead) must contain
- "u3phya_ref": for reference clock of usb3.0 analog phy.
-
-Required nodes : a sub-node is required for each port the controller
- provides. Address range information including the usual
- 'reg' property is used inside these nodes to describe
- the controller's topology.
-
-Optional properties (controller (parent) node):
- - reg : offset and length of register shared by multiple ports,
- exclude port's private register. It is needed on mt2701
- and mt8173, but not on mt2712.
-
-Required properties (port (child) node):
-- reg : address and length of the register set for the port.
-- clocks : a list of phandle + clock-specifier pairs, one for each
- entry in clock-names
-- clock-names : must contain
- "ref": 48M reference clock for HighSpeed analog phy; and 26M
- reference clock for SuperSpeed analog phy, sometimes is
- 24M, 25M or 27M, depended on platform.
-- #phy-cells : should be 1 (See second example)
- cell after port phandle is phy type from:
- - PHY_TYPE_USB2
- - PHY_TYPE_USB3
-
-Example:
-
-u3phy: usb-phy@11290000 {
- compatible = "mediatek,mt8173-u3phy";
- reg = <0 0x11290000 0 0x800>;
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
- status = "okay";
-
- u2port0: usb-phy@11290800 {
- reg = <0 0x11290800 0 0x100>;
- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- status = "okay";
- };
-
- u3port0: usb-phy@11290900 {
- reg = <0 0x11290800 0 0x700>;
- clocks = <&clk26m>;
- clock-names = "ref";
- #phy-cells = <1>;
- status = "okay";
- };
-
- u2port1: usb-phy@11291000 {
- reg = <0 0x11291000 0 0x100>;
- clocks = <&apmixedsys CLK_APMIXED_REF2USB_TX>;
- clock-names = "ref";
- #phy-cells = <1>;
- status = "okay";
- };
-};
-
-Specifying phy control of devices
----------------------------------
-
-Device nodes should specify the configuration required in their "phys"
-property, containing a phandle to the phy port node and a device type;
-phy-names for each port are optional.
-
-Example:
-
-#include <dt-bindings/phy/phy.h>
-
-usb30: usb@11270000 {
- ...
- phys = <&u2port0 PHY_TYPE_USB2>, <&u3port0 PHY_TYPE_USB3>;
- phy-names = "usb2-0", "usb3-0";
- ...
-};
-
-
-Layout differences of banks between mt8173/mt2701 and mt2712
--------------------------------------------------------------
-mt8173 and mt2701:
-port offset bank
-shared 0x0000 SPLLC
- 0x0100 FMREG
-u2 port0 0x0800 U2PHY_COM
