Hmm, I don't think so. The way I read the response from Rob was that
*my* device tree snippet should not assume that the i2c subsystem
ignores the vendor. So, I think that even w/o this patch a DT entry
like
mcp4651-104@28 {
compatible = "microchip,mcp4651-104";
reg = <0x28>;
};
will work, precisely since i2c ignores the microchip, part (and thus
allows you to omit/misspell it). I.e. I think that Rob is concerned
with how the DT is documented/defined, and not so much about how it
is then implemented in Linux.
I haven't actually tested that though, so I may be completely wrong
in all of the above statements...
Cheers,
Peter
