Subject: [PATCH v6 07/13] platform/x86: lenovo-wmi-other: Add missing CPU tunable attributes
Date: Tue, 31 Mar 2026 18:12:02 +0000	[thread overview]
Message-ID: <20260331181208.421552-8-derekjohn.clark@gmail.com> (raw)
In-Reply-To: <20260331181208.421552-1-derekjohn.clark@gmail.com>

Use an enum for all device ID's and CPU attribute feature ID's,
add missing CPU attributes.

v4:
  - Align type ID defines.
  - Align CPU feature enum values.
  - remove cpu_oc_stat from Documentation.
v3:
  - Remove cpu_oc_stat.
