Dmitry Baryshkov authored
Since commit 8f59ee9a ("drm/msm/dsi: Adjust probe order"), the DSI host gets initialized earlier, but this caused unability to probe the entire stack of components because they all depend on interrupts coming from the main `mdss` node (mdp5, or dpu1). To fix this issue, move mdss device initialization (which include irq domain setup) to msm_mdev_probe() time, as to make sure that the interrupt controller is available before dsi and/or other components try to initialize, finally satisfying the dependency.

AngeloGioacchino Del Regno authored
In preparation for registering the mdss interrupt controller earlier, move the allocation of msm_drm_private from component bind time to msm_drv probe; this also allows us to use the devm variant of kzalloc. Since it is not right to allocate the drm_device at probe time (as it should exist only when all components are bound, and taken down when components get cleaned up), the only way to make this happen is to pass a pointer to msm_drm_private as driver data (like done in many other DRM drivers), instead of one to drm_device like it's currently done in this driver. This is also simplifying some bind/unbind functions around drm/msm, as some of them are using drm_device just to grab a pointer to the msm_drm_private structure, which we now retrieve in one call.

Re-work the boost and idle clamping to use PM QoS requests instead, so they get aggreggated with other requests (such as cooling device). This does have the minor side-effect that devfreq sysfs min_freq/ max_freq files now reflect the boost and idle clamping, as they show (despite what they are documented to show) the aggregated min/max freq. Fixing that in devfreq does not look straightforward after considering that OPPs can be dynamically added/removed.

This regresses some of the 30 fps usecases where the workload on gpu (at 33ms internval) is very small which it can finish at the lowest OPP before the deadline.
