From 3baf264bcdcd8c498807c65bf7bd271f399e6ea9 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 31 Aug 2023 21:55:09 +0200 Subject: [PATCH] arm64: dts: imx8mp: Simplify USB C on DH i.MX8M Plus DHCOM PDK3 Remove the connector as well as all the links and only connect the PTN5150 with xHCI controller. This is sufficient to implement the role switching. Furthermore, this makes resume work without hanging. Without this patch, the platform would hang on resume of 'connector'.
