Marek Vasut 35b38dd6a7 arm64: dts: imx8mp: Fix LAN8740Ai PHY reference clock on DH electronics i.MX8M Plus DHCOM
[ Upstream commit c63749a7dd ]

Add missing 'clocks' property to LAN8740Ai PHY node, to allow the PHY driver
to manage LAN8740Ai CLKIN reference clock supply. This fixes sporadic link
bouncing caused by interruptions on the PHY reference clock, by letting the
PHY driver manage the reference clock and assure there are no interruptions.

This follows the matching PHY driver recommendation described in commit
bedd8d78ab ("net: phy: smsc: LAN8710/20: add phy refclk in support")

Fixes: 8d6712695b ("arm64: dts: imx8mp: Add support for DH electronics i.MX8M Plus DHCOM and PDK2")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
