malidp_pm_suspend_late checks if the runtime status is not suspended and if so, invokes malidp_runtime_pm_suspend which disables the display engine/core interrupts and the clocks. It sets the runtime status as suspended. The difference between suspend() and suspend_late() is as follows:- 1. suspend() makes the device quiescent. In our case, we invoke the DRM helper which disables the CRTC. This would have invoked runtime pm suspend but the system suspend process disables runtime pm. 2. suspend_late() It continues the suspend operations of the drm device which was started by suspend(). In our case, it performs the same functionality as runtime_suspend(). The complimentary functions are resume() and resume_early(). In the case of resume_early(), we invoke malidp_runtime_pm_resume() which enables the clocks and the interrupts. It sets the runtime status as active. If the device was in runtime suspend mode before system suspend was called, pm_runtime_work() will put the device back in runtime suspended mode( after the complete system has been resumed).
