Add COMPILE_TEST dependency to force exynos driver to
built for more than arm and to built modules
that otherwise required other symbols to be de-selected.
This will increase build coverage of the exynos driver
thus allowing most trivial build errors to be detected/fixed early.
This introduces one warning when built using sh:
exynos7_drm_decon.c: In function ‘decon_remove’:
exynos7_drm_decon.c:769:24: warning: unused variable ‘ctx’
struct decon_context *ctx = dev_get_drvdata(&pdev->dev);
This is due to the definition of iounmap() in sh,
and nothing that exynos driver can fix.
Include fix of exynos build for alpha.

Jani wrote the idential patch, so for posterity:
The static keyword was apparently accidentally removed in commit
08fa8fd0faa5 ("drm/i915: Switch to per-crtc vblank vfuncs"), leading to
sparse warning:
drivers/gpu/drm/i915/i915_irq.c:3382:6: warning: symbol

Make the function static again.

Transfer size of zero means a request to do an address-only
transfer. Since the HW support this, we probably shouldn't be just
ignoring such requests. While at it allow DP_AUX_I2C_MOT flag to pass
through, since it is supported by the HW as well.

tc_wait_pll_lock() is always called as a follow-up for updating
PLLUPDATE and PLLEN bit of a given PLL control register. To simplify
things, merge the two operation into a single helper function
tc_pllupdate() and convert the rest of the code to use it. No

Don't assume that requested data transfer size is the same as amount
of data that was transferred. Change the code to get that information
from DP0_AUXSTATUS instead.
Since the check for AUX_BUSY in tc_aux_get_status() is pointless (it
will always called after tc_aux_wait_busy()) and there's only one user
of it, inline its code into tc_aux_transfer() instead of trying to
accommodate the change above.

According to the datasheet tc358767 can transfer up to 16 bytes via
its AUX channel, so the artificial limit of 8 appears to be too
low. However only up to 15-bytes seem to be actually supported and
trying to use 16-byte transfers results in transfers failing
sporadically (with bogus status in case of I2C transfers), so limit it
to 15.

Simplify AUX data write by dropping index arithmetic and shifting and
replacing it with a call to a helper function that does two things:
1. Copies user-provided data into a write buffer
2. Transfers contents of the write buffer to up to 4 32-bit
registers on the chip
Note that separate data endianness fix:
tmp = (tmp << 8) | buf[i];
that was reserved for DP_AUX_I2C_WRITE looks really strange, since it
will place data differently depending on the passed user-data
size. E.g. for a write of 1 byte, data transferred to the chip would
look like:
[byte0] [dummy1] [dummy2] [dummy3]
whereas for a write of 4 bytes we'd get:
[byte3] [byte2] [byte1] [byte0]
Since there's no indication in the datasheet that I2C write buffer
should be treated differently than AUX write buffer and no comment in
the original code explaining why it was done this way, that special
I2C write buffer transformation was dropped in this patch.

A very unfortunate aspect of tc_write()/tc_read() macro helpers is
that they capture quite a bit of context around them and thus require
the caller to have magic variables 'ret' and 'tc' as well as label
'err'. That makes a number of code paths rather counter-intuitive and
somewhat clunky, for example tc_stream_clock_calc() ends up being like
this:
int ret;
tc_write(DP0_VIDMNGEN1, 32768);
return 0;
err:
return ret;
which is rather surprising when you read the code for the first
time. Since those helpers arguably aren't really saving that much code
and there's no way of fixing them without making them too verbose to
be worth it change the driver code to not use them at all.

With the subdirectories we lost the ability to build individual files on
the command line, for example:
$ make drivers/gpu/drm/i915/display/intel_display.o
This was due to the top level directory missing from header search
path. Add the header search paths to subdir Makefiles.
Note that none of the other options in the top level i915 Makefile are
taken into account when building individual files. Usually this is not a
concern.

We're now guaranteed to no longer race against prepare_fb/cleanup_fb,
which means we can access ->vaddr without having to hold a lock.
Before the previous patches it was fairly easy to observe the cursor
->vaddr being invalid, but that's now gone, so we can upgrade to a
full WARN_ON.

The crc computation worker needs to be able to get at some data
structures and framebuffer mappings, while potentially more atomic
updates are going on. The solution thus far is to copy relevant bits
around, but that's very tedious.
Here's a new approach, which tries to be more clever, but relies on a
few not-so-obvious things:
- crtc_state is always updated when a plane_state changes. Therefore
we can just stuff plane_state pointers into a crtc_state. That
solves the problem of easily getting at the needed plane_states.
- with the flushing changes from previous patches the above also holds
without races due to the next atomic update being a bit eager with
cleaning up pending work - we always wait for all crc work items to
complete before unmapping framebuffers.
- we also need to make sure that the hrtimer fires off the right
worker. Keep a new distinct crc_state pointer, under the
vkms_output->lock protection for this. Note that crtc->state is
updated very early in the atomic commit, way before we arm the
vblank event - the vblank event should always match the buffers we
use to compute the crc. This also solves an issue in the hrtimer,
where we've accessed drm_crtc->state without holding the right locks
(we held none - oops).
- in the worker itself we can then just access the plane states we
need, again solving a bunch of ordering and locking issues.
Accessing plane->state requires locks, accessing the private
vkms_crtc_state->active_planes pointer only requires that the memory
doesn't get freed too early.
The idea behind vkms_crtc_state->active_planes is that this would
contain all visible planes, in z-order, as a first step towards a more
generic blending implementation.
Note that this patch also fixes races between prepare_fb/cleanup_fb
and the crc worker accessing ->vaddr.

Currently, we flush pending CRC workers very late in the commit flow,
when we destroy all the old crtc states. Unfortunately, at that point,
the framebuffers are already unpinned (and our vaddr possible gone), so
this isn't good. Also, the plane_states we need might also already be
cleaned up, since cleanup order of state structures isn't well defined.
Fix this by waiting for all CRC workers of the old state to complete
before we start any of the cleanup work. For correct ordering and
avoiding races, we can only flush_work after
drm_atomic_helper_wait_for_vblanks() since we know that all subsequent
queue_work will be for the new state. Only once that's done is
flush_work() useful, before that we might flush the work, and then right
after the hrtimer that simulates vblank queues it again. Every time you
have a flush_work before cleaning up the work structure, the following
sequence must be obeyed, or it can go wrong:
1. Make sure no one else can re-queue the work anymore (in our case
that's done by a combination of first updating output->crc_state and
then waiting for the vblank to pass to make sure the hrtimer has noticed
that change).
2. flush_work()
3. Actually clean up stuff (which isn't done here).
Doing the flush_work before we even completed the output->state update,
much less waited for the vblank to make sure that's happened, missed the
point.
Note that this is not yet race-free because of the hrtimer and crc
worker look at the wrong state pointers, but that will be fixed in
subsequent patches.

The issue we have is that the crc worker might fall behind. We've
tried to handle this by tracking both the earliest frame for which it
still needs to compute a crc, and the last one. Plus when the
crtc_state changes, we have a new work item, which are all run in
order due to the ordered workqueue we allocate for each vkms crtc.
Trouble is there's been a few small issues in the current code:
- we need to capture frame_end in the vblank hrtimer, not in the
worker. The worker might run much later, and then we generate a lot
of crc for which there's already a different worker queued up.
- frame number might be 0, so create a new crc_pending boolean to
track this without confusion.
- we need to atomically grab frame_start/end and clear it, so do that
all in one go. This is not going to create a new race, because if we
race with the hrtimer then our work will be re-run.
- only race that can happen is the following:
1. worker starts
2. hrtimer runs and updates frame_end
3. worker grabs frame_start/end, already reading the new frame_end,
and clears crc_pending
4. hrtimer calls queue_work()
5. worker completes
6. worker gets re-run, crc_pending is false
Explain this case a bit better by rewording the comment.
v2: Demote warning level output to debug when we fail to requeue, this
is expected under high load when the crc worker can't quite keep up.

TDA998x updates:
- improve the driver's approach to audio, adding support for more I2S
based formats, particularly other justifications, and preparing the
driver to support other bclk ratios.
- add support for pixel repeated modes, tested with a Panasonic TV.
- correct the quantisation range handling; in particular, do not send
full range RGB to the sink when the sink does not support full range
RGB.
- Send the HDMI vendor info frame when required.
