From ffbf3a8be76613d83c41de40312235cb7cb2cbe4 Mon Sep 17 00:00:00 2001 From: Abel Vesa Date: Mon, 2 Dec 2024 11:23:17 +0200 Subject: [PATCH] arm64: dts: qcom: x1e78100-t14s: Enable support for both Type-A USB ports The Thinkpad T14s has 2 USB-A ports, both connected to the USB multiport controller, each one via a separate NXP PTN3222 eUSB2-to-USB2 redriver to the eUSB2 PHY for High-Speed support, with a dedicated QMP PHY for SuperSpeed support. Describe each redriver and then enable each pair of PHYs and the USB controller itself, in order to enable support for the 2 USB-A ports.
