From: Nicolas Frattaroli Date: Sat, 12 Nov 2022 17:04:01 +0100 Subject: arm64: dts: rockchip: Enable PCIe 2 on SOQuartz CM4IO Origin: https://git.kernel.org/linus/3736aa7ecc4cd9b4abce30052bad00aba4f0362f This patch enables the PCIe2 on the CM4IO board when paired with a SOQuartz CM4 System-on-Module board. combphy2 also needs to be enabled in this case to make the PHY work for this.
