From 5c1037196b9ee75897c211972de370ed1336ec8f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 10 Jan 2018 17:10:11 +0100 Subject: [PATCH] ARM: dts: s5pv210: add interrupt-parent for ohci 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.
