[edk2-devel] [PATCH edk2-platforms v1 4/6] Platform/ARM: Juno: Remove PL050 KMI description from DSDT

[Sami Mujawar]

Remove the PL050 PS/2 Keyboard/Mouse Interface (KMI) controller
description from the Juno DSDT as:
 - PS/2 ports are now considered as legacy ports. Alternatively,
   a USB Keyboard/Mouse can be connected to Juno USB ports.
 - Concurrent usage of the Juno KMI and USB appear to trigger
   I/O errors from the USB mass storage driver. This has proven
   to be problematic as USB drivers typically cannot recover from
   this issue.
