Subject: [PATCH v2 1/2] dt-bindings: phy: mediatek,tphy: allow simple nodename pattern
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@...43000: node has a unit name, but no reg or ranges property
For a node like this:
sata_phy: t-phy@...43000 {
ranges;
sata_port: sata-phy@...43000 {
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@...43000 {
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.
