[v7] Linux SBI MPXY and RPMI drivers

[PATCH v7 16/24] ACPI: scan: Update honor list for RPMI System MSI

Posted by Anup Patel 5 months, 2 weeks ago

From: Sunil V L <sunilvl@ventanamicro.com>

The RPMI System MSI interrupt controller (just like PLIC and APLIC)
needs to probed prior to devices like GED which use interrupts provided
by it. Also, it has dependency on the SBI MPXY mailbox device.

Add HIDs of RPMI System MSI and SBI MPXY mailbox devices to the honor
list so that those dependencies are handled.
