[PATCH 5.10 071/252] serial: 8250_dw: Add device HID for new AMD UART controller

[Greg Kroah-Hartman]

From: Maximilian Luz <luzmaximilian@xxxxxxxxx>

commit 3c35d2a960c0077a4cb09bf4989f45d289332ea0 upstream.

Add device HID AMDI0022 to the AMD UART controller driver match table
and create a platform device for it. This controller can be found on
Microsoft Surface Laptop 4 devices and seems similar enough that we can
just copy the existing AMDI0020 entries.
