The idea is that gem_prime_export is deprecated in favor of
obj_funcs.export. That's much easier to do if both have matching
function signatures.

This is a no-op on atomic drivers because with atomic it's simply too
complicated to get all the locking and workers and nonblocking
synchronization correct, from essentially an NMI context. Well, too
complicated = impossible. Also, omapdrm never implemented the
mode_set_base_atomic hook, so I kinda wonder why this was ever added.
Drop the hooks.

Drivers must fill out the handle_to_fd and fd_to_handle hooks to
enable export/import prime functionality already. The additional
DRIVER_PRIME flag doesn't serve any real purpose, since the overall
flag doesn't even tell you whether import or export or maybe even both
is supported.
Ditch it.
This patch just makes it defunct, subsequent patches will remove it
from all the drivers.
Note this changes the userspace visible errno in some situations from
EOPNOTSUPP to ENOSYS. Userspace already needs to treat both as "no
prime support", so this should break anything.
v2: Improve commit message as suggested by Emil

Yes this is a bit a big patch, but since it's essentially a complete
rewrite of all the prime docs I didn't see how to better split it up.
Changes:
- Consistently point to drm_gem_object_funcs as the preferred hooks,
where applicable.
- Document all the hooks in &drm_driver that lacked kerneldoc.
- Completely new overview section, which now also includes the cleaned
up lifetime/reference counting subchapter. I also mentioned the weak
references in there due to the lookup caches.
- Completely rewritten helper intro section, highlight the
import/export related functionality.
- Polish for all the functions and more cross references.
I also sprinkled a bunch of todos all over.
Most important: 0 code changes in here. The cleanup motivated by
reading and improving all this will follow later on.
v2: Actually update the prime helper docs. Plus add a few FIXMEs that
I won't address right away in subsequent cleanup patches.
v3:
- Split out the function moving. This patch is now exclusively
documentation changes.
- Typos and nits (Sam).
v4: Polish suggestions from Noralf.

Add a KMS driver for the Ingenic JZ47xx family of SoCs.
This driver is meant to replace the aging jz4740-fb driver.
This driver does not make use of the simple pipe helper, for the reason
that it will soon be updated to support more advanced features like
multiple planes, IPU integration for colorspace conversion and up/down
scaling, support for DSI displays, and TV-out and HDMI outputs.
Notes:
v2: - Remove custom handling of panel. The panel is now discovered using
the standard API.
- Lots of small tweaks suggested by upstream
v3: - Use devm_drm_dev_init()
- Update compatible strings to -lcd instead of -drm
- Add destroy() callbacks to plane and crtc
- The ingenic,lcd-mode is now read from the bridge's DT node
v4: Remove ingenic,lcd-mode property completely. The various modes are now
deduced from the connector type, the pixel format or the bus flags.
v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers
- Use 32bpp framebuffer instead of 16bpp, as it'll work with both
16-bit and 24-bit panel
- Get rid of drm_format_plane_cpp() which has been dropped upstream
- Avoid using drm_format_info->depth, which is deprecated.

Rotations and reflections setup are needed in some scenarios to initialise
properly the initial framebuffer. Some drivers already had a bunch of
quirks to deal with this, such as either a private kernel command line
parameter (omapdss) or on the device tree (various panels).
In order to accomodate this, let's create a video mode parameter to deal
with the rotation and reflexion.

The drm subsystem also uses the video= kernel parameter, and in the
documentation refers to the fbdev documentation for that parameter.
However, that documentation also says that instead of giving the mode using
its resolution we can also give a name. However, DRM doesn't handle that
case at the moment. Even though in most case it shouldn't make any
difference, it might be useful for analog modes, where different standards
might have the same resolution, but still have a few different parameters
that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

The drm_client_rotation has a check on the rotation value, but the
reflections are also stored in the same variable, and the check doesn't
take this into account.
Therefore, even though we might have a valid rotation, if we're also using
a reflection parameter, the test will fail for no particular reason.

The drm_client_modeset_commit_atomic function uses two times the
plane_state variable in inner blocks of code, but the variable has a scope
global to this function.
This will lead to inadvertent devs to reuse the variable in the second
block with the value left by the first, without any warning from the
compiler since value would have been initialized.
Fix this by moving the variable declaration to the proper scope.

Since commit 4b050ba7a66c ("MIPS: pgtable.h: Implement the
pgprot_writecombine function for MIPS") and commit c4687b15a848 ("MIPS: Fix
definition of pgprot_writecombine()") write-combine vma mapping is
available to be used by kernel subsystems for MIPS. In particular the
uncached accelerated attribute is requested to be set by ioremap_wc()
method and by generic PCI memory pages/ranges mapping methods. The same
is done by the drm_io_prot()/ttm_io_prot() functions in case if
write-combine flag is set for vma's passed for mapping. But for some
reason the pgprot_writecombine() method calling is ifdefed to be a
platform-specific with MIPS system being marked as lacking of one. At the
very least it doesn't reflect the current MIPS platform implementation.
So in order to improve the DRM subsystem performance on MIPS with UCA
mapping enabled, we need to have pgprot_writecombine() called for buffers,
which need store operations being combined. In case if particular MIPS
chip doesn't support the UCA attribute, the mapping will fall back to
noncached.

Expose performance counters through 2 driver specific ioctls: one to
enable/disable the perfcnt block, and one to dump the counter values.
There are discussions to expose global performance monitors (those
counters that can't be retrieved on a per-job basis) in a consistent
way, but this is likely to take time to settle on something that works
for various HW/users.
The ioctls are marked unstable so we can get rid of them when the time
comes. We initally went for a debugfs-based interface, but this was
making the transition to per-FD address space more complicated (we need
to specify the namespace the GPU has to use when dumping the perf
counters), hence the decision to switch back to driver specific ioctls
which are passed the FD they operate on and thus will have a dedicated
address space attached to them.
Other than that, the implementation is pretty simple: it basically dumps
all counters and copy the values to a userspace buffer. The parsing is
left to userspace which has to know the specific layout that's used
by the GPU (layout differs on a per-revision basis).

We plan to expose performance counters through 2 driver specific
ioctls until there's a solution to expose them in a generic way.
In order to be able to deprecate those ioctls when this new
infrastructure is in place we add an unsafe module parameter that
will keep those ioctls hidden unless it's set to true (which also
has the effect of tainting the kernel).
All unstable ioctl handlers should use panfrost_unstable_ioctl_check()
to check whether they're supposed to handle the request or reject it
with ENOSYS.

Pull timer fixes from Thomas Gleixner:
"A set of small fixes:
- Repair the ktime_get_coarse() functions so they actually deliver
what they are supposed to: tick granular time stamps. The current
code missed to add the accumulated nanoseconds part of the
timekeeper so the resulting granularity was 1 second.
- Prevent the tracer from infinitely recursing into time getter
functions in the arm architectured timer by marking these functions
notrace

In vop_crtc_mode_fixup() we fixup the mode to show what we actually
will be able to achieve. However we should base our adjustments on
any previous adjustments that were made.
As an example, the dw_hdmi driver may wish to make some small
adjustments to clock rates in its atomic_check() function. If it
does, it will update the adjusted_mode. We shouldn't throw away those
adjustments.
NOTE: the version of the dw_hdmi driver upstream doesn't _actually_
make such adjustments, but downstream in Chrome OS it does. It is
plausible that one day we'll figure out how to cleanly make that
happen in an upstream-friendly way, so we should prepare by using the
right mode.

When fixing up the clock in vop_crtc_mode_fixup() we're not doing it
quite correctly. Specifically if we've got the true clock 266666667 Hz,
we'll perform this calculation:
266666667 / 1000 => 266666
Later when we try to set the clock we'll do clk_set_rate(266666 *
1000). The common clock framework won't actually pick the proper clock
in this case since it always wants clocks <= the specified one.
Let's solve this by using DIV_ROUND_UP.
