Yes. As OF_DEV_AUXDATA_ID still requires hardware information like
0x48000100 as below, it seems it is not
consistent with the origin purpose of ARM DT.
OF_DEV_AUXDATA_ID("ti,omap-i2c", 0x48000100, "omap-i2c.1", 1,&i2c_pdata)
And the information 0x48000100 is something that doesn't want to be in
kernel codes.it should be only in dts.
FWIW, I do not care about the physical address at all. This is just used
by the of_dev_lookup function to get the proper instance for a device
compatible type.
That's the only way for the OF_DEV_AUXDATA to work, but in theory you
could do the same as soon as you provide the id. So OF_DEV_AUXDATA_ID
could avoid it.
Since OF_DEV_AUXDATA_ID seems to be already dead before it even reaches
the mainline, let's forget about that.
