#     rtc: opal: Fix OPAL RTC driver OPAL_BUSY loops
#     
#     The OPAL RTC driver does not sleep in case it gets OPAL_BUSY or
#     OPAL_BUSY_EVENT from firmware, which causes large scheduling
#     latencies, up to 50 seconds have been observed here when RTC stops
#     responding (BMC reboot can do it).
#     
#     Fix this by converting it to the standard form OPAL_BUSY loop that
#     sleeps.
#     
#     Fixes: 628daa8d5abf ("powerpc/powernv: Add RTC and NVRAM support plus RTAS fallbacks")
