No I don't think it should and have patches that drop the mali-midgard from the example + rk3288 dtsi to not confuse people: - https://patchwork.kernel.org/patch/9832811/ - https://patchwork.kernel.org/patch/9832807/ Devicetree supposedly should not contain wildcards and without knowing for real that all of then in fact are compatible we should not assume so [and that's hard to check with all the secrecy :-) ] .

Well, when they do get a name in the form of "<vendor>,<foo>.txt", the "<vendor>,<foo>" is usually at least *a* valid compatible string. For example, "nvidia,gk20a.txt" has several other strings, but its filename is one of the supported ones. Anyway, that wasn't my main worry. I was mostly curious about the body of the text. > > > @@ -0,0 +1,86 @@ > > > +ARM Mali Midgard GPU > > > +==================== > > > + > > > +Required properties: > > > + > > > +- compatible : > > > + * Must contain one of the following: > > > + + "arm,mali-t604" > > > + + "arm,mali-t624" > > > + + "arm,mali-t628" > > > + + "arm,mali-t720" > > > + + "arm,mali-t760" > > > + + "arm,mali-t820" > > > + + "arm,mali-t830" > > > + + "arm,mali-t860" > > > + + "arm,mali-t880" > > > + * which must be preceded by one of the following vendor specifics: > > > + + "amlogic,meson-gxm-mali" > > > + + "rockchip,rk3288-mali" > > > > But it's not listed here. > > > > > + > > > +- reg : Physical base address of the device and length of the register > > > area. + > > > +- interrupts : Contains the three IRQ lines required by Mali Midgard > > > devices. + > > > +- interrupt-names : Contains the names of IRQ resources in the order they > > > were + provided in the interrupts property.

The important part is that having only arm,mali-midgard in the gpu node is not enough to accurately describe the hardware, which is why it is not listed in the required compatible strings. On the other hand, it does help with describing the hardware, so it's fine to use it. If people find this confusing then I guess we could add something to say that arm,mali-midgard can be used optionally in addition to the specific ones. Also, if you look at the 64-bit ARM CPUs for example, they typically have armv8 in their node although armv8 is not mentioned anywhere in the bindings documentation... Guillaume

Sorry I've only just seen Heiko's other emails and patches about removing arm,mali-midgard from the example. Guillaume
