When chaning dts files in arch/arm64/boot/dts/marvell, use subject prefix arm64: dts: marvell: for espressobin for example arm64: dts: marvell: espressobin: instead of dts: espressobin or dts: aardvark Marek On Wed, 15 Apr 2020 18:00:48 +0200 Pali Rohár <pali@kernel.org> wrote: > Previously aardvark PCI controller set speed to gen2.

Previously aardvark PCI controller set speed to gen2. Now it reads speed from Device Tree and as default use maximal possible speed which is gen3. Because Espressobin has advertised only PCI Express 2.0 capability and previous value was gen2, define max-link-speed to 2, so there would not be any configuration change.
