tests: Test suspend/resume on active pipelines
Provide a test to verify the hardware completes a functional test whilst performing a suspend resume cycle in parallel. Make use of the /sys/power/pm_test functionality provided by CONFIG_PM_DEBUG to perform the testing Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
