drm/msm/mdp5: update irqs on crtc<->encoder link change

2014-12-18T19:32:14+00:00

If crtc <-> encoder linkage changes, we could end up with the CRTC
listening for the wrong error or vsync irqs.  Generally this problem
would correct itself relatively quickly, since we update the global
irqmask after dispatching irqs, but to be sure let the CRTC trigger
update_irq().

drm/msm: block incoming update on pending updates

2014-12-18T19:32:14+00:00

We can't have multiple updates pending on a given CRTC, and we don't
want a sync update to race w/ an async update that preceeded it.  So
keep track of which CRTCs have updates in flight, and block later
updates that would conflict.

drm/plane: Pass old state to ->atomic_update()

2014-11-25T12:27:58+00:00

In most situations it will be useful to have the old state passed to the
->atomic_update() callback. For example if a plane is being disabled the
new state's .crtc field will be NULL, but some drivers may rely on this
field to program the CRTCs registers.

v2: rename variable to old_plane_state and remove redundant comment as
suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to
drm-next and add a hunk for pending MSM mdp5 changes

drm/msm/mdp4: fix mixer setup for multi-crtc + planes

2014-11-21T20:32:37+00:00

On mdp4 there is a single global LAYERMIXER_IN_CFG register.  The
previous logic to share that between multiple crtcs didn't actually
handle plane-disable very well.  Easier just to look at all of the
crtcs each time.

drm/msm/mdp5: dpms(OFF) cleanups

2014-11-21T13:59:24+00:00

When disabling the interface (INTF), the change doesn't latch until next
vblank, so we need to wait for vblank.

Also, to be pedantic, in the crtc, set all the mixer stages to unused.
It shouldn't really matter, since at this point we have already disabled
the INTF and waited for necessary vblank.

drm/msm/mdp5: atomic

2014-11-21T13:59:18+00:00

Convert mdp5 over to atomic helpers.  Extend/wrap drm_plane_state to
track plane zpos and to keep track of the needed when applying the
atomic update.  In mdp5's plane->atomic_check() we also need to check
for updates which require SMP reallocation, in order to trigger full
modeset.

drm/msm/mdp5: remove global mdp5_ctl_mgr

2014-11-21T13:57:21+00:00

A bit cleaner.. and won't resulting in an attempt to kfree() a static
global in unload path.

drm/msm/mdp5: don't use void * for opaque types

2014-11-21T13:57:20+00:00

For example, use 'struct mdp5_smp *' everywhere instead of 'void *', but
only declare it as 'struct mdp5_smp;' in common headers, so the struct
body is still private.  The accomplishes the desired modularity while
still letting the compiler provide some type checking for us.

drm/msm: add multiple CRTC and overlay support

2014-11-21T13:57:19+00:00

MDP5 currently support one single CRTC with its private pipe.
This change allows the configuration of multiple CRTCs with
the possibility to attach several public planes to these CRTCs.
