Hi Inki,

This patchset contains fixes and improvements related to SW-TRIGGER.
The core patch moves all TE related stuff from panel(bindings) and
HDMI(irq handler) to DECON. This move allows to fix races between interrupt
handlers and DECON disable. It allows also to eliminate all DECON flags and
related checks in subsequent patches. Additionally SW-TRIGGER can be enabled
by adding TE interrupt to DECON dts node.
Another important fix is uncoditional SW-TRIGGER during enabled VBLANKs, this
way no VBLANK timeouts happens when drm-core or userspace waits for VBLANK.

First 5 patches could be treated as fixes, but since they depends on my previous
work which is not yet merged, I have not separated it.

As I said before the patchset depends on my vblank patchset[1] and recent fix
of hdmi pipeline disable order[2].
