Add the device tree bindings for the MaxLinear GPY2xx PHYs. Signed-off-by: Michael Walle <redacted> --- Is the filename ok? I was unsure because that flag is only for the GPY215 for now. But it might also apply to others. Also there is no compatible string, so.. .../bindings/net/maxlinear,gpy2xx.yaml | 47 +++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/maxlinear,gpy2xx.yaml
