From 3dd97e70450f899bad68f348e5be94c68a2f7b72 Mon Sep 17 00:00:00 2001 From: Jonathan Bell Date: Wed, 24 Jan 2024 16:32:13 +0000 Subject: [PATCH 0854/1085] dts: rp1: nobble HS and FS/LS park mode for dwc3 xhci Synopsys have recommended that we disable this feature entirely, as Superspeed park mode can hang the controller, and Hs/FS/LS park mode can cause performance degradation with bursty devices.
