From 2d60bf2d14a8d9146c3bef48326ce677df03e334 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Wed, 12 Jan 2022 14:39:46 +0000 Subject: [PATCH] ARM: dts: Remove VL805 USB node from CM4 dts Neither the CM4 module nor the CM4IO board have a VL805 USB3 controller. The existing "usb@0,0" node is a hangover from the Pi 4 dts; delete it. An up-to-date firmware will automatically load the vl805 overlay on CM4s with VL805=1 in the EEPROM config, ensuring that the firmware is notified of any PCIe reset.
