Subject: [SRU][R][PATCH 0/1] platform/x86/amd/pmf: Add AMDI0112 ACPI ID

BugLink: https://bugs.launchpad.net/bugs/2165251

[ Impact ]

To support PMF driver on new AMD silicon, ID AMDI0112 needs to be added into the PMD driver.

[ Fix ]

Backport the following patch:

1. [PATCH] platform/x86/amd/pmf: Add AMDI0112 ACPI ID[1]

[ Test Plan ]

Boot the kernel with the said patch. The PMF driver should bind.

[ Where problems could occur ]

Unless there is existing hardware using this ID already (which likely would be an BIOS issue), this is new hardware enablement, so nothing earlier to regress from.

Although it's just adding an ID, this patch won't apply on 7.0-oem, because it depends on the code context from [2] and [3], which are PMF support for even newer silicon. It'll take another 2 patch series (12 patches) to make this patch apply cleanly and PMF for this ID doesn't need those patches to work. This ID is added at this point of time as an afterthought for older silicon.

Originally I sent this to 7.0-oem kernel only. However, comment in [1] seems to imply that it's more desirable to send this to generic. So send it here.
