Some DRM drivers lacked the drm_panel.h include to use drm_panel_put()
after the commit b71a623598d3 ("drm/panel: of_drm_find_panel() return a counted reference").

Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge()
receive a pointer with no reference held, creating a window where
the panel device can be unregistered and freed between the lookup
and first use (e.g., drm_panel_prepare()).
Fix the lookup function by acquiring a reference with drm_panel_get()
before returning, under panel_lock. Callers are now responsible for
calling drm_panel_put() when they no longer need the pointer.
For bridge drivers that immediately wrap the panel in a panel_bridge
(which acquires its own reference), release the lookup reference right
after the bridge creation call.
For analogix-anx6345, which stores the panel for direct use, release
the reference in the i2c remove path.
For platform drivers using analogix_dp_core with a component lifecycle
(exynos_dp, rockchip analogix_dp), release the lookup reference in the
platform remove() function. The panel_bridge created during bind() holds
a separate reference that devm cleanup releases after remove() returns.
Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in
bridge/panel.c itself, update a second batch of drivers calling
of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the
lookup reference after wrapping the panel in a bridge, and handle the
cases where a panel is found but cannot be used, dropping the reference
immediately in those paths.

lcdif_attach_bridge() uses dev_err_probe() on all its error returns to
store a specific deferral message.
However its caller lcdif_load() calls dev_err_probe() again on error,
overwriting the specific deferral messages with a unique, unavoidably
generic, message.
Make the specific deferral message visible by using a plain 'return ret' on
the caller.

It is necessary to wait for the full frame to finish streaming
through the DMA engine before we can safely disable it by removing
the DISP_PARA_DISP_ON bit. Disabling it in-flight can leave the
hardware confused and unable to resume streaming for the next frame.
This causes the FIFO underrun and empty status bits to be set and
a single solid color to be shown on the display, coming from one of
the pixels of the previous frame. The issue occurs sporadically when
a new mode is set, which triggers the crtc disable and enable paths.
Setting the shadow load bit and waiting for it to be cleared by the
DMA engine allows waiting for completion.
The NXP BSP driver addresses this issue with a hardcoded 25 ms sleep.

The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.
Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.
We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.
This patch was created using:
rg -l drm_atomic_state | \
xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'

Convert this driver to DRM_BRIDGE_ATTACH_NO_CONNECTOR and to the
drm_bridge_connector framework which is the current DRM bridge best
practice.
Based on the in-tree dts[i] files this introduces no regression. Based on
the kernel doc of drm_bridge_connector.c:
* To make use of this helper, all bridges in the chain shall report bridge
* operation flags (&drm_bridge->ops) and bridge output type
* (&drm_bridge->type), as well as the DRM_BRIDGE_ATTACH_NO_CONNECTOR attach
* flag (none of the bridges shall create a DRM connector directly).
and each of the 3 LCDIF blocks in the i.MX8MP, all of them comply with the
above requirement:
* For the LCDIF3, the pipeline is:
LCDIF3 -> fsl,imx8mp-hdmi-pvi -> fsl,imx8mp-hdmi-tx -> HDMI connector
And the involved bridges are:
* fsl,imx8mp-hdmi-pvi has ops = 0 (it doesn't set it) because it
implements none the optional features mentioned by those flags, and it
honors the DRM_BRIDGE_ATTACH_NO_CONNECTOR by propagating it
* fsl,imx8mp-hdmi-tx is implemented based on dw-hdmi, which sets ops as
appropriate and also propagates the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag
* display-connector (enabled via the DT overlay if needed) sets ops and
makes DRM_BRIDGE_ATTACH_NO_CONNECTOR mandatory
* The LCDIF2 involves the panel-bridge, display-connector and lvds-decoder
(even though only the pane-bridge is currently supported), and all these
three also set ops as needed and propagate
DRM_BRIDGE_ATTACH_NO_CONNECTOR or make it mandatory.
* The LCDIF1 is used with the adv7511, tc358767 and the panel bridge
drivers which also comply with the requirements.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Decouple drm_get_format_info() from struct drm_mode_fb_cmd2 and just
pass the pixel format+modifier combo in by hand.
We may want to use drm_get_format_info() outside of the normal

creating a temporary one just for this seems silly.

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

In case an upstream bridge modified the required clock frequency
in its .atomic_check callback by setting adjusted_mode.clock ,
make sure that clock frequency is generated by the LCDIFv3 block.
This is useful e.g. when LCDIFv3 feeds DSIM which feeds TC358767
with (e)DP output, where the TC358767 expects precise timing on
its input side, the precise timing must be generated by the LCDIF.

In case the LCDIF is enabled in DT but unused, the clocks used by the
LCDIF are not enabled. Those clocks may even have a use count of 0 in
case there are no other users of those clocks. This can happen e.g. in
case the LCDIF drives HDMI bridge which has no panel plugged into the
HDMI connector.
Do not attempt to disable clocks in the suspend callback and re-enable
clocks in the resume callback unless the LCDIF is enabled and was in
use before the system entered suspend, otherwise the driver might end
up trying to disable clocks which are already disabled with use count
0, and would trigger a warning from clock core about this condition.
Note that the lcdif_rpm_suspend() and lcdif_rpm_resume() functions
internally perform the clocks disable and enable operations and act
as runtime PM hooks too.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert the mxsfb driver from always returning zero in the
remove callback to the void returning variant.

Ignoring errors from devm_clk_get() is wrong. To handle not all platforms
having an axi clk use devm_clk_get_optional() instead and do proper error
handling.
Also the clk API handles NULL as a dummy clk (which is also returned by
devm_clk_get_optional() if there is no clk) so there is no need to check
for NULL before calling clk_prepare_enable() or its counter part.
