      ACPI / processor_idle: Add support for Low Power Idle(LPI) states · a36a7fec
      Sudeep Holla authored
      ACPI 6.0 introduced an optional object _LPI that provides an alternate
      method to describe Low Power Idle states. It defines the local power
      states for each node in a hierarchical processor topology. The OSPM can
      use _LPI object to select a local power state for each level of processor
      hierarchy in the system. They used to produce a composite power state
      request that is presented to the platform by the OSPM.
      
      Since multiple processors affect the idle state for any non-leaf hierarchy
      node, coordination of idle state requests between the processors is
      required. ACPI supports two different coordination schemes: Platform
      coordinated and  OS initiated.
      
      This patch adds initial support for Platform coordination scheme of LPI.

      ACPI / processor_idle: introduce ACPI_PROCESSOR_CSTATE · 35ae7133
      Sudeep Holla authored
      ACPI 6.0 adds a new method to specify the CPU idle states(C-states)
      called Low Power Idle(LPI) states. Since new architectures like ARM64
      use only LPIs, introduce ACPI_PROCESSOR_CSTATE to encapsulate all the
      code supporting the old style C-states(_CST).
      
      This patch will help to extend the processor_idle module to support
      LPI.

      ACPI / video: mark acpi_video_get_levels() inline · e4f35c13
      Arnd Bergmann authored
      A recent patch added a stub function for acpi_video_get_levels when
      CONFIG_ACPI_VIDEO is disabled. However, this is marked as 'static'
      and causes a warning about an unused function whereever the header
      gets included:
      
      In file included from ../drivers/gpu/drm/radeon/radeon_acpi.c:28:0:
      include/acpi/video.h:74:12: error: 'acpi_video_get_levels' defined but not used [-Werror=unused-function]
      
      This makes the declaration 'static inline', which gets rid of the
      warning.
