   8 commit 5628a8ca14149ba4226e3bdce3a04c3b688435ad upstream.

  10 According to the comment added to exynos_dt_pmu_match[] in commit
  11 8b283c025443 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"),
  12 the RTC is not able to wake up the system through the PMU on Exynos5410,
  13 unlike Exynos5420.
  14
  15 However, when the RTC DT node got added, it was a straight copy of
  16 the Exynos5420 node, which now causes a warning from dtc.
  17
  18 This removes the incorrect interrupt-parent, which should get the
  19 interrupt working and avoid the warning.
