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.
