From b6267a396e1cc57b62dac5dd010f78d66b68bae4 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Mon, 4 Jul 2022 12:13:18 +0200 Subject: [PATCH] arm64: dts: mediatek: cherry: Enable T-PHYs and USB XHCI controllers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add USB functionality by enabling the required PHYs and the XHCI controllers. This enables all of the supported USB ports on the Cherry boards. Please note that u3phy1 also enables u3port1, which is configured to be a PCI-Express PHY for the second PCIe controller that is found on the MT8195 SoC, which will be enabled in a later commit.
