i simply mirrored the current board file (which only sets the irq number).

not sure i'm following - can you elaborate?
i'll summarize the way i see it. please correct me if i'm wrong.
both wl18xx and wl12xx use the platform data to get the irq number.
wl12xx (only) also needs some additional clock definitions to be
passed. there's currently some issue with specifying some the of clock
sources, so i preferred starting only with (the simpler) wl18xx
bindings.
for platforms with wl18xx, we can remove the pdata-quirk, as all the
data (i.e. irq) can be passed by the new DT bindings.
however, for platforms with wl12xx, we still need to pass the clock
definitions (along with the irq), so we have to keep
legacy_init_wl12xx for the time being (and that's also why we have to
currently keep the platform_data handling in the wlcore driver)
do you have something else in mind?
Eliad.
