| 8 | commit 5c1037196b9ee75897c211972de370ed1336ec8f upstream. | |
| 9 | ||
| 10 | The ohci-hcd node has an interrupt number but no interrupt-parent, | |
| 11 | leading to a warning with current dtc versions: | |

| 19 | As seen from the related exynos dts files, the ohci and ehci controllers | |
| 20 | always share one interrupt number, and the number is the same here as | |
| 21 | well, so setting the same interrupt-parent is the reasonable solution | |
| 22 | here. | |
