| Subject: ARM: dts: s5pv210: add interrupt-parent for ohci |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| commit 5c1037196b9ee75897c211972de370ed1336ec8f upstream. |
| |
| The ohci-hcd node has an interrupt number but no interrupt-parent, |
| leading to a warning with current dtc versions: |
| |
| arch/arm/boot/dts/s5pv210-aquila.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 |
| arch/arm/boot/dts/s5pv210-goni.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 |
| arch/arm/boot/dts/s5pv210-smdkc110.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 |
| arch/arm/boot/dts/s5pv210-smdkv210.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 |
| arch/arm/boot/dts/s5pv210-torbreck.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000 |
| |
| As seen from the related exynos dts files, the ohci and ehci controllers |
| always share one interrupt number, and the number is the same here as |
| well, so setting the same interrupt-parent is the reasonable solution |
| here. |
