Normally these are called from within drm core, from the EDID parsing
code. But for dual-dsi in some drivers (at least drm/msm) we need to
call these from the driver. So they should be exported.

Note that only one external display interface is present in this

once drm/msm driver supports DSI connectors.

SMP blocks are configured for specific client IDs (ports).
These client IDs can be different from one chip to another for a
given pipe.
e.g.: DMA0 pipe fetch Y component is connected to:
- port #10 for MDP5 v1.3
- port #4 for MDP5 v1.6
In order to be compatible for upcoming versions of MDP5, the
client ID list is passed through the MDP5 config module rather
than using a list of hard-coded enum values.

MDP block is actually contained inside the MDSS block. For some

Like CTL and LM blocks, this changes introduce a dynamic offset

Some interfaces (WB, DSI Command Mode) need to be kicked off
through a START Signal. This signal needs to be sent at the right
time and requests in some cases to keep track of the pipeline

buffers are ready, in case of WB interface).

DSI and WB interfaces need a more complex pipeline configuration
than the current mdp5_ctl_set_intf().
For example, memory output connections need to be selected for
WB. Interface mode (Video vs. Command modes) also need to be
configured for DSI.
This change takes care of configuring the whole pipeline as far
as operation mode goes. DSI and WB interfaces will be added
later.

MDP5 hardware has some limitation and requires to avoid flushing
registers more than once between two Vblanks.
This change removes all FLUSH operations (except for HW cursor)
beside the one coming from a CRTC's ->atomic_flush().
This avoid this type of behavior (eg: CRTC + 1 plane overlay):
[drm:mdp5_crtc_vblank_irq] vblank
[drm:mdp5_ctl_commit] flush (20048) CTL + LM0 + RGB0
[drm:mdp5_ctl_commit] flush (20040) CTL + LM0
[drm:mdp5_crtc_vblank_irq] blank
[drm:mdp5_ctl_commit] flush (20049) CTL + LM0 + RGB0 + VIG0
[drm:mdp5_crtc_vblank_irq] blank
and replaces it by:
[drm:mdp5_crtc_vblank_irq] vblank
[drm:mdp5_ctl_commit] flush (20048) CTL + LM0 + RGB0
[drm:mdp5_crtc_vblank_irq] blank
[drm:mdp5_ctl_commit] flush (20049) CTL + LM0 + RGB0 + VIG0

Users of the atomic state assume that if the pointer to a crtc, plane or
connector is not NULL in the respective object vector, than the state
for that object in *_states vector also won't be NULL. That assumption
was broken by drm_atomic_state_clear(), which would clear the state
pointer but leave the pointer to the object still set.
This fixes a NULL pointer dereference in i915 caused by the use of
drm_atomic_state_clear().

- Lines-wise, largest is a PXA fix for dealing with interrupts on DT that was

it seemed appropriate to include now
- Some GPIO fixes for OMAP platforms added a few lines. This was also fixes for

- Small OMAP timer fix to behave better with partially upstreamed platforms,

Dots aren't usually used in node names even though ePAPR permits

arm: pxa: fixes for v4.0-rc5
There are only 2 fixes, one for the zeus board about the regulator changes,
where a typo prevented the zeus board from having a working can regulator,
and one regression triggered by the interrupts IRQ shift of 16 affecting all
boards.

Pull x86 fix from Ingo Molnar:
"Fix x86 syscall exit code bug that resulted in spurious non-execution
of TIF-driven user-return worklets, causing big trouble for things
like KVM that rely on user notifiers for correctness of their vcpu
model, causing crashes like double faults"

Pull parsic fixes from Helge Deller:
"One patch from Mikulas fixes a bug on parisc by artifically
incrementing the counter in pmd_free when the kernel tries to free
the preallocated pmd.
Other than that we now prevent that syscalls gets added without
incrementing __NR_Linux_syscalls and fix the initial pmd setup code
if a default page size greater than 4k has been selected"

parisc: Fix pmd code to depend on PT_NLEVELS value, not on CONFIG_64BIT

parisc: Add compile-time check when adding new syscalls
