During board bringups its useful to have a DSI test pattern
generator to isolate a DPU vs a DSI issue and focus on the relevant
hardware block.
To facilitate this, add an API which triggers the DSI controller
test pattern. The expected output is a rectangular checkered pattern.
This has been validated on a single DSI video mode panel by calling it
right after drm_panel_enable() which is also the ideal location to use
this as the DSI host and the panel have been initialized by then.
Further validation on dual DSI and command mode panel is pending.
If there are any fix ups needed for those, it shall be applied on top
of this change.
Changes in v2:
- generate the new dsi.xml.h and update the bitfield names

For existing adrenos, there is one or more ringbuffer, depending on
whether preemption is supported. When preemption is supported, each
ringbuffer has it's own priority. A submitqueue (which maps to a
gl context or vk queue in userspace) is mapped to a specific ring-
buffer at creation time, based on the submitqueue's priority.
Each ringbuffer has it's own drm_gpu_scheduler. Each submitqueue
maps to a drm_sched_entity. And each submit maps to a drm_sched_job.

Previously the (non-fd) fence returned from submit ioctl was a raw
seqno, which is scoped to the ring. But from UABI standpoint, the
ioctls related to seqno fences all specify a submitqueue. We can
take advantage of that to replace the seqno fences with a cyclic idr
handle.
This is in preperation for moving to drm scheduler, at which point
the submit ioctl will return after queuing the submit job to the
scheduler, but before the submit is written into the ring (and
therefore before a ring seqno has been assigned). Which means we
need to replace the dma_fence that userspace may need to wait on
with a scheduler fence.

This adds a few things to try and make frequency scaling better match
the workload:
1) Longer polling interval to avoid whip-lashing between too-high and
too-low frequencies in certain workloads, like mobile games which
throttle themselves to 30fps.
Previously our polling interval was short enough to let things
ramp down to minimum freq in the "off" frame, but long enough to
not react quickly enough when rendering started on the next frame,
leading to uneven frame times. (Ie. rather than a consistent 33ms
it would alternate between 16/33/48ms.)
2) Awareness of when the GPU is active vs idle. Since we know when
the GPU is active vs idle, we can clamp the frequency down to the
minimum while it is idle. (If it is idle for long enough, then
the autosuspend delay will eventually kick in and power down the
GPU.)
Since devfreq has no knowledge of powered-but-idle, this takes a
small bit of trickery to maintain a "fake" frequency while idle.
This, combined with the longer polling period allows devfreq to
arrive at a reasonable "active" frequency, while still clamping
to minimum freq when idle to reduce power draw.
3) Boost. Because simple_ondemand needs to see a certain threshold
of busyness to ramp up, we could end up needing multiple polling
cycles before it reacts appropriately on interactive workloads
(ex. scrolling a web page after reading for some time), on top
of the already lengthened polling interval, when we see a idle
to active transition after a period of idle time we boost the
frequency that we return to.

gcc doesn't care, but clang quite reasonably pointed out that the recent
commit e9ba16e68c ("smpboot: Mark idle_init() as __always_inlined to
work around aggressive compiler un-inlining") did some really odd
things:
kernel/smpboot.c:50:20: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier]
static inline void __always_inline idle_init(unsigned int cpu)
^
which not only has that duplicate inlining specifier, but the new
__always_inline was put in the wrong place of the function definition.
We put the storage class specifiers (ie things like "static" and
"extern") first, and the type information after that. And while the
compiler may not care, we put the inline specifier before the types.
So it should be just
static __always_inline void idle_init(unsigned int cpu)
instead.

Pull timer fixes from Thomas Gleixner:
"A small set of timer related fixes:
- Plug a race between rearm and process tick in the posix CPU timers
code
- Make the optimization to avoid recalculation of the next timer
interrupt work correctly when there are no timers pending"
