GTA02 used to poll the PMU continuously when in the bootmenu. We know from GTA01 that this causes conflicts with USB. I've now extended the unbusy patch also for GTA02.
(Note: it doesn't really matter if we fail to clear all interrupts in one sweep here. We'll get any stragglers in the next round.) - Werner ----------------------------------- Changes ----------------------------------- Extended unbusying also to the GTA02. unbusy-i2c.patch: - board/neo1973/gta02/gta02.c (neo1973_new_second, neo1973_on_key_pressed): do not poll incessantly but only when the PMU has posted an interrupt - board/neo1973/gta02/gta02.c (have_int, pwr_int_pending): detect when one of the interrupts we're looking for has occurred
