Subject: [PATCH v4] platform/x86: bitland-mifs-wmi: Fix TM2107 profile handling
Date: Thu, 22 Oct 2026 12:02:21 -0300	[thread overview]
Message-ID: <20261022150221.26879-1-matias.civadda2342001@gmail.com> (raw)

The TIMI Redmi Book Pro 14 2022 (TM2107) stores the MIFS WMI return
code at the end of the response and uses different profile values:
0 for performance, 1 for balanced and 2 for low power.

Add a DMI entry using the existing quirks infrastructure to select
the correct response layout and profile mapping.

Skip the adapter-type query on this model to allow performance mode
with its USB-C charger, while retaining the external-power check.

Changes in v4:
- Rebase onto Mingyou Chen's complete v13 series.
