With the input_configured() callback in place, the setup and frame synchronization can be simplified. The input device initialization is moved to mt_input_configured(), to make sure the full HID report has been seen.

A hid device may create several input devices, and a driver may need to prepare or finalize the configuration per input device. Currently, there is no sane way for a driver to know when a device has been configured. This patch adds a callback providing that information.

Some devices use an internal key for tracking which cannot be directly mapped to slots. This patch provides a key-to-slot mapping, which can be used by drivers of such devices.

With the INPUT_MT_TRACK flag set, the function input_mt_assign_slots() can be used to match a new set of contacts against the currently used slots. The algorithm used is based on Lagrange relaxation, and performs very well in practice; slower than mtdev for a few corner cases, but faster in most commonly occuring cases.

Most MT drivers perform the same actions on frame synchronization. Some actions, like dropping unseen contacts, are also unnecessarily complex. Collect common frame synchronization tasks in a new function, input_mt_sync_frame(). Depending on the flags set, it drops unseen contacts and performs pointer emulation. With init flags and frame synchronization in place, most MT drivers can be simplified. First out are the bcm5974 and hid-multitouch drivers, following this patch.

By sending a full frame of events at the same time, the irqsoff latency at heavy load is brought down from 200 us to 100 us.

On heavy event loads, such as a multitouch driver, the irqsoff latency can be as high as 250 us. By accumulating a frame worth of data before passing it on, the latency can be dramatically reduced. As a side effect, the special EV_SYN handling can be removed, since the frame is now atomic. This patch adds the events() handler callback and uses it if it exists. The latency is improved by 50 us even without the callback.

The events-per-packet estimate has so far been used by MT devices only. This patch adjusts the packet buffer size to also accomodate the KEY and MSC events. Keyboards normally send one or two keys at a time. MT devices normally send a number of button keys along with the MT information. The buffer size chosen here covers those cases, and matches the default buffer size in evdev. Since the input estimate is now preferred, remove the special input-mt estimate.

[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).

Power gating is per crtc pair, but the powergating registers should be called individually. The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.

The ordering is important and the current drm code wasn't cutting it for modern DIG encoders. We need to have information about crtc before setting up the encoders so I've shifted the ordering a bit.

Checking of the second colorbuffer was skipped on r700, because CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff, so we must set the number of samples of the second colorbuffer to 1 in order to pass the CS checker. The DRM version is bumped, because RESOLVE_BOX is always rejected without this fix on r600.
