Hi Javier,

Yeah that sounds reasonable. mcb_bus_add_devices() calls device_attach()
for the respective IP cores, so they individual driver's ->probe() function
shouldn't be called before mcb_bus_add_devices(). So you could shrink
the resource between chameleon_parse_cells() and mcb_add_devices().

Btw, mcb-lpc.c needs the same fix as well.

Byte,
