I'd prefer to not do this with linker sections if possible. Doesn't
PPC have machine descriptors that you could add the match table to? If
that table exists then arch_want_default_of_probe could return a
pointer to it.
Are there any platforms that work with the default match table? I'd be
fine with adding some strings to the default if that helps.
{ .type = "soc", },
device_type is deprecated for FDT, so this shouldn't be needed except
for really old stuff.
{ .compatible = "soc", },
Doesn't appear in kernel dts files. Could be out of tree or old ones?
{ .compatible = "simple-bus" },
Already handled.
{ .compatible = "gianfar" },
Seems like the children of this should be probed by the gianfar driver.
{ .compatible = "gpio-leds", },
I don't think this is needed.
{ .type = "qe", },
Again, deprecated.
{ .compatible = "fsl,qe", },
No issue to add this. Though, you could also probe it from mpc85xx_qe_init().
