The pattern for the nodename only allows t-phy@... , however, for the case when the t-phy has no `reg` and only `ranges` (basically when the t-phy is just a parent node), dtc will throw this warning: Warning (unit_address_vs_reg): /t-phy@1a243000: node has a unit name, but no reg or ranges property For a node like this: sata_phy: t-phy@1a243000 { ranges; sata_port: sata-phy@1a243000 { reg = <0 0x1a243000 0 0x0100>; }; }; it is normal that the parent node 't-phy' would be without any address, as in: sata_phy: t-phy { ranges; sata_port: sata-phy@1a243000 { reg = <0 0x1a243000 0 0x0100>; }; }; because being just a holder it does not have its own reg. However the binding does not allow such a name for the t-phy, so with this patch, making the `@[0-9a-f]+` part optional, such node is possible.

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.
