Documentation/devicetree/bindings/phy/no-op.txt

+NOP PHY driver
+
+This driver is used to stub PHY operations in a driver (USB, SATA).
+This is useful when the 'client' driver (USB, SATA, ...) uses the PHY framework
+and there is no actual PHY harwdare to drive.
+
+Required properties:
+- compatible     : must contain "nop-phy"
+- #phy-cells     : must contain <0>
+
+Example:
+
+nop_phy {
+	compatible = "nop-phy";
+	#phy-cells = <0>;
+};

Documentation/devicetree/bindings/phy/phy-stm32-usbphyc.txt

+STMicroelectronics STM32 USB HS PHY controller
+
+The STM32 USBPHYC block contains a dual port High Speed UTMI+ PHY and a UTMI
+switch. It controls PHY configuration and status, and the UTMI+ switch that
+selects either OTG or HOST controller for the second PHY port. It also sets
+PLL configuration.

+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide

+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded,
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.

 To make this easier, such license headers in the source files will be

-in a source file the full "GPL v2.0 or later" header text will be

-
-	SPDX-License-Identifier:	GPL-2.0+

-Ideally, the license terms of all files in the source tree should be

 If a "SPDX-License-Identifier:" line references more than one Unique
 License Identifier, then this means that the respective file can be
 used under the terms of either of these licenses, i. e. with
 
-	SPDX-License-Identifier:	GPL-2.0+	BSD-3-Clause
+	SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
 
 you can choose between GPL-2.0+ and BSD-3-Clause licensing.

+License identifier syntax
+-------------------------
+
+1. Placement:
+
+   The SPDX license identifier in U-Boot files shall be added at the first
+   possible line in a file which can contain a comment.  For the majority
+   or files this is the first line, except for scripts which require the
+   '#!PATH_TO_INTERPRETER' in the first line.  For those scripts the SPDX
+   identifier goes into the second line.
+
+|
+
+2. Style:
+
+   The SPDX license identifier is added in form of a comment.  The comment
+   style depends on the file type::
+
+      C source:	// SPDX-License-Identifier: <SPDX License Expression>
+      C header:	/* SPDX-License-Identifier: <SPDX License Expression> */
+      ASM:	/* SPDX-License-Identifier: <SPDX License Expression> */
+      scripts:	# SPDX-License-Identifier: <SPDX License Expression>
+      .rst:	.. SPDX-License-Identifier: <SPDX License Expression>
+      .dts{i}:	// SPDX-License-Identifier: <SPDX License Expression>
+
+   If a specific tool cannot handle the standard comment style, then the
+   appropriate comment mechanism which the tool accepts shall be used. This
+   is the reason for having the "/\* \*/" style comment in C header
+   files. There was build breakage observed with generated .lds files where
+   'ld' failed to parse the C++ comment. This has been fixed by now, but
+   there are still older assembler tools which cannot handle C++ style
+   comments.
+
+|
+
+3. Syntax:
+
+   A <SPDX License Expression> is either an SPDX short form license
+   identifier found on the SPDX License List, or the combination of two
+   SPDX short form license identifiers separated by "WITH" when a license
+   exception applies. When multiple licenses apply, an expression consists
+   of keywords "AND", "OR" separating sub-expressions and surrounded by
+   "(", ")" .
+
+   License identifiers for licenses like [L]GPL with the 'or later' option
+   are constructed by using a "+" for indicating the 'or later' option.::
+
+      // SPDX-License-Identifier: GPL-2.0+
+      // SPDX-License-Identifier: LGPL-2.1+
+
+   WITH should be used when there is a modifier to a license needed.
+   For example, the linux kernel UAPI files use the expression::
+
+      // SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
+      // SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
+
+   Other examples using WITH exceptions found in the linux kernel are::
+
+      // SPDX-License-Identifier: GPL-2.0 WITH mif-exception
+      // SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
+
+   Exceptions can only be used with particular License identifiers. The
+   valid License identifiers are listed in the tags of the exception text
+   file.
+
+   OR should be used if the file is dual licensed and only one license is
+   to be selected.  For example, some dtsi files are available under dual
+   licenses::
+
+      // SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
+
+   Examples from U-Boot for license expressions in dual licensed files::
+
+      // SPDX-License-Identifier: GPL-2.0 OR MIT
+      // SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
+
+   AND should be used if the file has multiple licenses whose terms all
+   apply to use the file. For example, if code is inherited from another
+   project and permission has been given to put it in U-Boot, but the
+   original license terms need to remain in effect::
+
+      // SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
+
+   Another other example where both sets of license terms need to be
+   adhered to is::
+
+      // SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+
+
