George Moussalem says: ==================== Add support for the IPQ5018 Internal GE PHY The IPQ5018 SoC contains an internal Gigabit Ethernet PHY with its output pins that provide an MDI interface to either an external switch in a PHY to PHY link architecture or directly to an attached RJ45 connector. The PHY supports 10BASE-T/100BASE-TX/1000BASE-T link modes in SGMII interface mode, CDT, auto-negotiation and 802.3az EEE. The LDO controller found in the IPQ5018 SoC needs to be enabled to drive power to the CMN Ethernet Block (CMN BLK) which the GE PHY depends on. The LDO must be enabled in TCSR by writing to a specific register. In a phy to phy architecture, DAC values need to be set to accommodate for the short cable length. ==================== Link: https://patch.msgid.link/20250613-ipq5018-ge-phy-v5-0-9af06e34ea6b@outlook.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
