Subject: [PATCH 0/2] amd-pstate: Add unit tests for state machine

From: Mario Limonciello <mario.limonciello@....com>

The state machine for amd-pstate allows changing from any supported
mode to another.  This is a relatively large matrix of possible moves
that doesn't have test coverage.

Walk through the matrix as part of amd-pstate-ut tests to make sure
that all transitions work.

Mario Limonciello (2):
  cpufreq/amd-pstate: Export symbols for changing modes
  cpufreq/amd-pstate-ut: Add test case for mode switches
