According to disable Documentation/admin-guide/kernel-parameters.txt, this
parameter can be used to disable kernel modesetting.
DRM drivers will not perform display-mode changes or accelerated rendering
and only the system framebuffer will be available if it was set-up.
But only a few DRM drivers currently check for nomodeset, make this driver
to also support the command line parameter.

Pull drm updates from Dave Airlie:
"Highlights:
- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward
This has all been audited with known userspace, but there may be
some pitfalls that were missed.
- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs
- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support
- amdgpu adds support for Cyan Skillfish
- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.
Otherwise the usual smattering of stuff everywhere, panels, bridges,
refactorings.

The conversion to drm managed resources introduced two bugs: the plane is now
always initialized with the linear-only list, while the list with the Vivante
GPU modifiers should have been used when the PRG/PRE engines are present. This
masked another issue, as ipu_plane_format_mod_supported() is now called before
the private plane data is set up, so if a non-linear modifier is supplied in
the plane modifier list, we run into a NULL pointer dereference checking for
the PRG presence. To fix this just remove the check from this function, as we
know that it will only be called with a non-linear modifier, if the plane init
code has already determined that the PRG/PRE is present.

Some standard resolutions like 1366x768 do not work properly with
i.MX6 SoCs, since the horizontal resolution needs to be aligned
to 8 pixels (so 1360x768 or 1368x768 would work).
This patch allocates framebuffers allocated to 8 pixels. The extra
time required to send the extra pixels are removed from the blank
time. In order to expose the correct display size to userspace,
the stride is increased without increasing the width.
Without this patch systems with this display resolution hang
indefinitely during boot up.

drm_atomic_helper_commit_hw_done() is the last thing (no plane cleanup
apparrently), so it's the entire function. And a nice comment
explaining why the wait_for_flip_done is ahead, unlike the usual
sequence.
Aside, I think since the atomic helpers do track plane disabling now
separately this might no longer be a real problem since:

When CONFIG_OF is disabled, building with 'make W=1' produces warnings
about out of bounds array access:
drivers/gpu/drm/imx/imx-ldb.c: In function 'imx_ldb_set_clock.constprop':
drivers/gpu/drm/imx/imx-ldb.c:186:8: error: array subscript -22 is below array bounds of 'struct clk *[4]' [-Werror=array-bounds]
Add an error check before the index is used, which helps with the
warning, as well as any possible other error condition that may be
triggered at runtime.
The warning could be fixed by adding a Kconfig depedency on CONFIG_OF,
but Liu Ying points out that the driver may hit the out-of-bounds
problem at runtime anyway.

Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.
Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.
This was made using the coccinelle script below:

Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_check hook, which would be the old
plane state in the global atomic state since _swap_state hasn't happened
when atomic_check is run.
Use the drm_atomic_get_old_plane_state helper to get that state to make
it more obvious.
This was made using the coccinelle script below:

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert all the remaining helpers to provide a consistent
interface, starting with the planes atomic_check.
The conversion was done using the coccinelle script below plus some
manual changes for vmwgfx, built tested on all the drivers.

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.
Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.
v3:
* remove out-comented line in drm_gem_framebuffer_helper.h
(Maxime)
v2:
* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
* add tutorial-style documentation

Use use drmm_crtc_alloc_with_planes() to align crtc memory lifetime
with the drm device. drm_crtc_cleanup() is called automatically before
the memory is freed.
Also use drmm_add_action_or_reset() to make sure IPU resources are
released automatically.

Also move the call to ipu_plane_get_resources() into ipu_plane_init()
and use drm managed resources to put IPU resources automatically when
required. Handle error return values of the plane property creation
functions.
