[net-next: PATCH v2 5/7] net: mvmdio: add ACPI support

From: Marcin Wojtas
Date: Wed Jun 16 2021 - 15:08:46 EST


This patch introducing ACPI support for the mvmdio driver by adding
acpi_match_table with two entries:

* "MRVL0100" for the SMI operation
* "MRVL0101" for the XSMI mode

Also clk enabling is skipped, because the tables do not contain
such data and clock maintenance relies on the firmware.
