From: Arnd Bergmann arnd@arndb.de

commit 5628a8ca14149ba4226e3bdce3a04c3b688435ad upstream.

According to the comment added to exynos_dt_pmu_match[] in commit 8b283c025443 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"), the RTC is not able to wake up the system through the PMU on Exynos5410, unlike Exynos5420.

However, when the RTC DT node got added, it was a straight copy of the Exynos5420 node, which now causes a warning from dtc.

This removes the incorrect interrupt-parent, which should get the interrupt working and avoid the warning.
