[PATCH v2 0/4] platform/surface: Add platform profile driver for Surface devices

[Maximilian Luz <luzmaximilian@gmail.com>]

This series adds a driver to provide platform profile support on 5th-
and later generation Microsoft Surface devices with a Surface System
Aggregator Module. On those devices, the platform profile can be used to
influence cooling behavior and power consumption.

To achieve this, a new platform profile is introduced: the
'balanced-performance' profile.

In addition, a couple of fix-ups are performed:
- Hide CONFIG_ACPI_PLATFORM_PROFILE and change drivers so that it is
  selected instead of depended on.
- Fix some references to documentation in a comment.

Note: This series (or more specifically "platform/surface: Add platform
profile driver") depends on the "platform/surface: Add Surface
Aggregator device registry" series.

Changes in v2:
 - Introduce new 'balanced-performance' platform profile and change
   profile mapping in driver.
 - Perform some fix-ups for the ACPI platform profile implementation:
   - Fix some references to documentation in a comment.
   - Hide CONFIG_ACPI_PLATFORM_PROFILE
