[PATCH v5 0/6] Merge redmi-wmi into bitland-mifs-wmi

From: Mingyou Chen

Date: Sun Aug 16 2026 - 06:08:42 EST


This patch series consolidates the standalone 'redmi-wmi' driver into the
'bitland-mifs-wmi' driver to eliminate code duplication and centralize
the maintenance of overlapping ACPI WMI event streams.

Bitland is the ODM manufacturer for various Xiaomi Redmibook models. Both
platforms share the exact same keyboard event stream WMI GUID
(46C93E13-EE9B-4262-8488-563BCA757FEF). While redmi-wmi previously parsed
the 4-byte payload as a bulk u32 scancode, bitland-mifs-wmi deconstructed
it into discrete type/id/value fields.

Redmi operations are not verified on real hardware, the operations are
reversed from the proprietary software (XiaomiGCommandCenter)

Additionally, this series cleans up the redundant Kconfig/Makefile hooks,
updates the MAINTAINERS entry accordingly, and introduces a newly reported
mic-mute hotkey definition for Redmibooks.

Testing status:
- Fully regression-tested on native Bitland hardware.
- Redmi-specific logic blocks are compile-tested only.
Feedback from Redmibook hardware owners is highly appreciated.

v5:
Correct Xiaomi DMI vendor name

v4:
Map PLATFORM_PROFILE_PERFORMANCE to wmi performance mode if the device
doesn't support full-speed mode.
