drm/edid: Fix HDMI VIC handling
Extract drm_mode_hdmi_vic() to correctly calculate the final HDMI
VIC for us. Currently this is being done a bit differently between
the AVI and HDMI infoframes. Let's get both to agree on this.
We need to allow the case where a mode is both 3D and has a HDMI
VIC. Currently we'll just refuse to generate the HDMI infoframe when
we really should be setting HDMI VIC to 0 and instead enabling 3D
stereo signalling.
If the sink doesn't even support the HDMI infoframe we should
not be picking the HDMI VIC in favor of the CEA VIC, because then
we'll end up not sending either VIC in the end.

drm: add mmap() to drm_gem_object_funcs
drm_gem_object_funcs->vm_ops alone can't handle everything which needs
to be done for mmap(), tweaking vm_flags for example. So add a new
mmap() callback to drm_gem_object_funcs where this code can go to.
Note that the vm_ops field is not used in case the mmap callback is
present, it is expected that the callback sets vma->vm_ops instead.
Also setting vm_flags and vm_page_prot is the job of the new callback.
so drivers have more control over these flags.
drm_gem_mmap_obj() will use the new callback for object specific mmap
setup. With this in place the need for driver-speific fops->mmap
callbacks goes away, drm_gem_mmap can be hooked instead.
drm_gem_prime_mmap() will use the new callback too to just mmap gem
objects directly instead of jumping though loops to make
drm_gem_object_lookup() and fops->mmap work.

drm/omap: add OMAP_BO flags to affect buffer allocation
On SoCs with DMM/TILER, we have two ways to allocate buffers: normal
dma_alloc or via DMM (which basically functions as an IOMMU). DMM can
map 128MB at a time, and we only map the DMM buffers when they are used
(i.e. not at alloc time). If DMM is present, omapdrm always uses DMM.
There are use cases that require lots of big buffers that are being used
at the same time by different IPs. At the moment the userspace has a
hard maximum of 128MB.
This patch adds three new flags that can be used by the userspace to
solve the situation:
OMAP_BO_MEM_CONTIG: The driver will use dma_alloc to get the memory.
This can be used to avoid DMM if the userspace knows it needs more than
128M of memory at the same time.
OMAP_BO_MEM_DMM: The driver will use DMM to get the memory. There's not
much use for this flag at the moment, as on platforms with DMM it is
used by default, but it's here for completeness.
OMAP_BO_MEM_PIN: The driver will pin the memory at alloc time, and keep
it pinned. This can be used to 1) get an error at alloc time if DMM
space is full, and 2) get rid of the constant pin/unpin operations which
may have some effect on performance.
If none of the flags are given, the behavior is the same as currently.

According to the docs and general consensus, select should only be used
for non user-visible symbols, but both RC_CORE and INPUT are
user-visible. Furthermore almost all other references to INPUT
throughout the kernel config are depends, not selects. For this reason
the first part of this change reverts the commit.
In order to address the original reason for the commit, namely
that not all boards use the remote controller functionality and hence
should not need have to deal with RC_CORE, the second part of this
change now makes the remote control support in the driver optional and
contingent on RC_CORE being defined. And with this the hard dependency
on INPUT also goes away as that is only needed if RC_CORE is defined
(which in turn already depends on INPUT).

drm/rockchip: Round up _before_ giving to the clock framework
I'm embarassed to say that even though I've touched
vop_crtc_mode_fixup() twice and I swear I tested it, there's still a
stupid glaring bug in it. Specifically, on veyron_minnie (with all
the latest display timings) we want to be setting our pixel clock to
66,666,666.67 Hz and we tell userspace that's what we set, but we're
actually choosing 66,000,000 Hz. This is confirmed by looking at the
clock tree.
The problem is that in drm_display_mode_from_videomode() we convert
from Hz to kHz with:
dmode->clock = vm->pixelclock / 1000;
...and drm_display_mode_from_videomode() is called from panel-simple
when we have an "override_mode" like we do on veyron_minnie. See
commit
123643e5c40a ("ARM: dts: rockchip: Specify
rk3288-veyron-minnie's display timings").
...so when the device tree specifies a clock of
66666667 for the panel
then DRM translates that to
66666000. The clock framework will always
pick a clock that is _lower_ than the one requested, so it will refuse
to pick
66666667 and we'll end up at
66000000.
While we could try to fix drm_display_mode_from_videomode() to round
to the nearest kHz and it would fix our problem, it wouldn't help if
the clock we actually needed was 60,000,001 Hz. We could
alternatively have DRM always round up, but maybe this would break
someone else who already baked in the assumption that DRM rounds down.
Specifically note that clock drivers are not consistent about whether
they round up or round down when you call clk_set_rate(). We know how
Rockchip's clock driver works, but (for instance) you can see that on
most Qualcomm clocks the default is clk_rcg2_ops which rounds up.
Let's solve this by just adding 999 Hz before calling
clk_round_rate(). This should be safe and work everywhere. As
discussed in more detail in comments in the commit, Rockchip's PLLs
are configured in a way that there shouldn't be another PLL setting
that is only a few kHz off so we won't get mixed up.
NOTE: if this is picked to stable, it's probably easiest to first pick
commit
527e4ca3b6d1 ("drm/rockchip: Base adjustments of the mode based
on prev adjustments") which shouldn't hurt in stable.

drm/panfrost: Handle resetting on timeout better
Panfrost uses multiple schedulers (one for each slot, so 2 in reality),
and on a timeout has to stop all the schedulers to safely perform a
reset. However more than one scheduler can trigger a timeout at the same
time. This race condition results in jobs being freed while they are
still in use.
When stopping other slots use cancel_delayed_work_sync() to ensure that
any timeout started for that slot has completed. Also use
mutex_trylock() to obtain reset_lock. This means that only one thread
attempts the reset, the other threads will simply complete without doing
anything (the first thread will wait for this in the call to
cancel_delayed_work_sync()).
While we're here and since the function is already dependent on
sched_job not being NULL, let's remove the unnecessary checks.

drm: two planes with the same zpos have undefined ordering
Currently the property docs don't specify whether it's okay for two planes to
have the same zpos value and what user-space should expect in this case.
The unspoken, legacy rule used in the past was to make user-space figure
out the zpos from object IDs. However some drivers break this rule,
that's why the ordering is documented as unspecified in case the zpos
property is missing. User-space should rely on the zpos property only.
There are some cases in which user-space might read identical zpos
values for different planes.
For instance, in case the property is mutable, user-space might set two
planes' zpos to the same value. This is necessary to support user-space
using the legacy DRM API where atomic commits are not possible:
user-space needs to update the planes' zpos one by one.
Because of this, user-space should handle multiple planes with the same
zpos.
While at it, remove the assumption that zpos is only for overlay planes.
Additionally, update the drm_plane_state.zpos docs to clarify that zpos
disambiguation via plane object IDs is a recommendation for drivers, not
something user-space can rely on. In other words, when user-space sets
the same zpos on two planes, drivers should rely on the plane object ID.
v2: clarify drm_plane_state.zpos docs (Daniel)
v3: zpos is for all planes (Marius, Daniel)
v4: completely reword the drm_plane_state.zpos docs to make it clear the
recommendation to use plane IDs is for drivers in case user-space uses
duplicate zpos values (Pekka)
v5: reword commit message (Pekka, James)
v6: remove mention of Arm GPUs having planes which can't overlap,
because this isn't uAPI yet (Daniel)

drm/drm_vblank: Change EINVAL by the correct errno
For historical reasons, the function drm_wait_vblank_ioctl always return
-EINVAL if something gets wrong. This scenario limits the flexibility
for the userspace to make detailed verification of any problem and take
some action. In particular, the validation of “if (!dev->irq_enabled)”
in the drm_wait_vblank_ioctl is responsible for checking if the driver
support vblank or not. If the driver does not support VBlank, the
function drm_wait_vblank_ioctl returns EINVAL, which does not represent
the real issue; this patch changes this behavior by return EOPNOTSUPP.
Additionally, drm_crtc_get_sequence_ioctl and
drm_crtc_queue_sequence_ioctl, also returns EINVAL if vblank is not
supported; this patch also changes the return value to EOPNOTSUPP in
these functions. Lastly, these functions are invoked by libdrm, which is
used by many compositors; because of this, it is important to check if
this change breaks any compositor. In this sense, the following projects
were examined:
* Drm-hwcomposer
* Kwin
* Sway
* Wlroots
* Wayland
* Weston
* Mutter
* Xorg (67 different drivers)
For each repository the verification happened in three steps:
* Update the main branch
* Look for any occurrence of "drmCrtcQueueSequence",
"drmCrtcGetSequence", and "drmWaitVBlank" with the command git grep -n
"STRING".
* Look in the git history of the project with the command
git log -S<STRING>
None of the above projects validate the use of EINVAL when using
drmWaitVBlank(), which make safe, at least for these projects, to change
the return values. On the other hand, mesa and xserver project uses
drmCrtcQueueSequence() and drmCrtcGetSequence(); this change is harmless
for both projects.

Delete the header files and delete the corresponding todo entry.
When we started this quest there was more than 700 users of drmP.h.
And drmP.h was a huge cover-it-all header file.
Daniel Vetter is the one that followed the work from start
to the end and in between many people have contributed to the
removal process - thanks to everyone!

drm: damage_helper: Fix race checking plane->state->fb
Since the dirtyfb ioctl doesn't give us any hints as to which plane is
scanning out the fb it's marking as damaged, we need to loop through
planes to find it.
Currently we just reach into plane state and check, but that can race
with another commit changing the fb out from under us. This patch locks
the plane before checking the fb and will release the lock if the plane
is not displaying the dirty fb.

The DSI driver misinterpreted the vbp term from the BSP code to refer
only to the backporch, when in fact it was backporch + sync. Thus the
driver incorrectly used the vertical front porch plus sync in its
calculation of the DRQ set bit value, when it should not have included
the sync timing.
Including additional sync timings leads to flip_done timed out as:

display via I2C, which is typically followed by a multi-byte
response. The internal I2C controller only allows single byte
reads/writes or reads of 8 sequential bytes, hence DDC/CI is not
supported when the internal I2C controller is used. The I2C
transfers complete without errors, however the data in the response

typical real-world scenario is that where one adapter is used when the

powered up.
The cec-notifier changes were made with that in mind, but I missed that in
order to support this you need to tell cec_notifier_cec_adap_unregister()
which adapter you are unregistering from the notifier.
Add this additional argument. It is currently unused, but once all drivers
