Samin Guo says: ==================== Add motorcomm phy pad-driver-strength-cfg support The motorcomm phy (YT8531) supports the ability to adjust the drive strength of the rx_clk/rx_data, and the default strength may not be suitable for all boards. So add configurable options to better match the boards.(e.g. StarFive VisionFive 2) The first patch adds a description of dt-bingding, and the second patch adds YT8531's parsing and settings for pad-driver-strength-cfg. Changes since v4: Patch 1: - Removed register-related DS(3b) values and added vol descriptions (by Andrew Lunn) - Dropped the type and added '-microamp' suffix. (by Rob Herring) Patch 2: - Return -EINVAL if the value in DT but it is invalid (by Andrew Lunn) Changes since v3: Patch 1: - Used current values instead of register values - Added units and numerical descriptions of driver-strength Patch 2: - Added a lookup table to listing the valid values in the schema (by Andrew Lunn) Changes since v2: Patch 2: - Readjusted the order of YT8531_RGMII_xxx to below YTPHY_PAD_DRIVE_STRENGTH_REG (by Frank Sae) - Reversed Christmas tree, sort these longest first, shortest last (by Andrew Lunn) - Rebased on tag v6.4 Changes since v1: Patch 1: - Renamed "rx-xxx-driver-strength" to "motorcomm,rx-xxx-driver-strength" (by Frank Sae) Patch 2: - Added default values for rxc/rxd driver strength (by Frank Sea/Andrew Lunn) - Added range checking when val is in DT (by Frank Sea/Andrew Lunn) Previous versions: v1 - https://patchwork.kernel.org/project/netdevbpf/cover/20230426063541.15378-1-samin.guo@starfivetech.com v2 - https://patchwork.kernel.org/project/netdevbpf/cover/20230505090558.2355-1-samin.guo@starfivetech.com v3 - https://patchwork.kernel.org/project/netdevbpf/cover/20230526090502.29835-1-samin.guo@starfivetech.com v4 - https://patchwork.kernel.org/project/netdevbpf/cover/20230714101406.17686-1-samin.guo@starfivetech.com ==================== Signed-off-by: David S.

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 Restructured Text 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.
