From 9af42385908bb4c33adf9f39af51ba269dbf9882 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Tue, 9 Apr 2024 13:42:10 +0200 Subject: [PATCH] arm64: dts: mediatek: mt8395-nio-12l: Enable PHYs and USB role switch Enable the PCIe0 PHY to be able to set calibrations read from eFuses, improving the stability and performance of the PCIe link. While at it, also enable the T-PHYs for both PCIe1 and for USB, allowing the USB ports to finally switch to gadget mode if needed, and configure the VBUS/ID pins of both USB ports for the same.
