Please split this patch into two patches. 1. A patch that updates arch/arm/boot/dts/r8a7791.dtsi I suggest calling that patch "ARM: shmobile: r8a7791: Add PCI device nodes" 2. A patch that updates arch/arm/boot/dts/r8a7791-koelsch.dts I suggest calling that patch "ARM: shmobile: koelsch: Add PCI device nodes"
