for_each_endpoint_of_node() requires a call to of_node_put() for every
early exit. A new error path was added to the loop without observing
this requirement.
Add the missing call to of_node_put() in the error path.

The assignment of the of_node to the aux bridge needs to mark the
of_node as reused as well, otherwise resource providers like pinctrl will
report a gpio as already requested by a different device when both pinconf
and gpios property are present.
Fix that by using the device_set_of_node_from_dev() helper instead.

It is impossible to add each and every possible DDP path combination
for each and every possible combination of SoC and board: right now,
this driver hardcodes configuration for 10 SoCs and this is going to
grow larger and larger, and with new hacks like the introduction of
mtk_drm_route which is anyway not enough for all final routes as the
DSI cannot be connected to MERGE if it's not a dual-DSI, or enabling
DSC preventively doesn't work if the display doesn't support it, or
others.
Since practically all display IPs in MediaTek SoCs support being
interconnected with different instances of other, or the same, IPs
or with different IPs and in different combinations, the final DDP
pipeline is effectively a board specific configuration.
Implement OF graphs support to the mediatek-drm drivers, allowing to
stop hardcoding the paths, and preventing this driver to get a huge
amount of arrays for each board and SoC combination, also paving the
way to share the same mtk_mmsys_driver_data between multiple SoCs,
making it more straightforward to add support for new chips.
Note that the OVL_ADAPTOR software component driver needs relatively
big changes in order to fully support OF Graphs (and more SoCs anyway)
and such changes will come at a later time.
As of now, the mtk_disp_ovl_adaptor driver takes the MERGE components
(for example, on mt8195, merge 1 to 4) dynamically so, even though
later updates to the ovl-adaptor driver will *not* require bindings
changes, the merge1-4 will be temporarily omitted in the graph for the
MT8195 SoC.
This means that an example graph for this SoC looks like:
mdp_rdma (0 ~ 7) -> padding (0 ~ 7) -> ethdr -> merge5
and the resulting path in this driver will be `ovl_adaptor -> merge5`
Later updates to the ovl adaptor will expand it to support more SoCs
and, in turn, to also fully support graphs.

The display IPs in MediaTek SoCs support being interconnected with
different instances of DDP IPs (for example, merge0 or merge1) and/or
with different DDP IPs (for example, rdma can be connected with either
color, dpi, dsi, merge, etc), forming a full Display Data Path that
ends with an actual display.
The final display pipeline is effectively board specific, as it does
depend on the display that is attached to it, and eventually on the
sensors supported by the board (for example, Adaptive Ambient Light
would need an Ambient Light Sensor, otherwise it's pointless!), other
than the output type.
Add support for OF graphs to most of the MediaTek DDP (display) bindings
to add flexibility to build custom hardware paths, hence enabling board
specific configuration of the display pipeline and allowing to finally
migrate away from using hardcoded paths.
Please note that - while this commit retains retro-compatibility with
old device trees - it will break the ABI for mediatek,dsi and for
mediatek,dpi for the sake of consistency between the `ports` in all
MediaTek DRM drivers versus DRM bridge drivers as in the previous
binding, MediaTek was using `port` (implicitly, port@0) as an OUTPUT,
while now the first port is an INPUT, and the second one is an OUTPUT,
which is consistent with other DRM drivers which can be chained to
drm/mediatek.
As for maintainability concerns, I am aware that the old device tree
will not be actively tested anymore, but retrocompatibility breakages
will *not* be more likely to happen in the future because any addition
to the graph (new drivers) will be done only for features present on
newer SoCs, keeping the old ones (and their default pipeline) untouched.

Allison Karlitskaya <allison.karlitskaya@redhat.com> says:
In context of my work on composefs/bootc I've been testing the new support
for directly mounting files with erofs (ie: without a loopback device) and
it's working well. Thanks for adding this feature --- it's a huge quality
of life improvement for us.
I've observed a strange behaviour, though: when mounting a file as an
erofs, if you read() the filesystem context fd, you always get the
following error message reported: Can't lookup blockdev.
That's caused by the code in erofs_fc_get_tree() trying to call
get_tree_bdev() and recovering from the error in case it was ENOTBLK and
CONFIG_EROFS_FS_BACKED_BY_FILE. Unfortunately, get_tree_bdev() logs the
error directly on the fs_context, so you get the error message even on
successful mounts.
It looks something like this at the syscall level:
fsopen("erofs", FSOPEN_CLOEXEC) = 3
fsconfig(3, FSCONFIG_SET_FLAG, "ro", NULL, 0) = 0
fsconfig(3, FSCONFIG_SET_STRING, "source", "/home/lis/src/mountcfs/cfs", 0)
= 0
fsconfig(3, FSCONFIG_CMD_CREATE, NULL, NULL, 0) = 0
fsmount(3, FSMOUNT_CLOEXEC, 0) = 5
move_mount(5, "", AT_FDCWD, "/tmp/composefs.upper.KuT5aV",
MOVE_MOUNT_F_EMPTY_PATH) = 0
read(3, "e /home/lis/src/mountcfs/cfs: Can't lookup blockdev\n", 1024) = 52
This is kernel 6.12.0-0.rc0.20240926git11a299a7933e.13.fc42.x86_64 from
Fedora Rawhide.
It's a pretty minor issue, but it sent me on a wild goose chase for an hour
or two, so probably it should get fixed before the final release.

As Allison reported [1], currently get_tree_bdev() will store
"Can't lookup blockdev" error message. Although it makes sense for
pure bdev-based fses, this message may mislead users who try to use
EROFS file-backed mounts since get_tree_nodev() is used as a fallback
then.
Add get_tree_bdev_flags() to specify extensible flags [2] and
GET_TREE_BDEV_QUIET_LOOKUP to silence "Can't lookup blockdev" message
since it's misleading to EROFS file-backed mounts now.

detection issue
Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state
detection issue.
The _LID device incorrectly returns the lid status as "closed" during
boot, causing the system to enter a suspend loop right after booting.
The quirk ensures that the correct lid state is reported initially,
preventing the system from immediately suspending after startup. It
only addresses the initial lid state detection and ensures proper
system behavior upon boot.

PRMT needs to find the correct type of block to translate the PA-VA
mapping for EFI runtime services.
The issue arises because the PRMT is finding a block of type
EFI_CONVENTIONAL_MEMORY, which is not appropriate for runtime services
as described in Section 2.2.2 (Runtime Services) of the UEFI
Specification [1]. Since the PRM handler is a type of runtime service,
this causes an exception when the PRM handler is called.
[Firmware Bug]: Unable to handle paging request in EFI runtime service
WARNING: CPU: 22 PID: 4330 at drivers/firmware/efi/runtime-wrappers.c:341
__efi_queue_work+0x11c/0x170
Call trace:
Let PRMT find a block with EFI_MEMORY_RUNTIME for PRM handler and PRM
context.
If no suitable block is found, a warning message will be printed, but
the procedure continues to manage the next PRM handler.
However, if the PRM handler is actually called without proper allocation,
it would result in a failure during error handling.
By using the correct memory types for runtime services, ensure that the
PRM handler and the context are properly mapped in the virtual address
space during runtime, preventing the paging request error.
The issue is really that only memory that has been remapped for runtime
by the firmware can be used by the PRM handler, and so the region needs
to have the EFI_MEMORY_RUNTIME attribute.

step, so that any issues with the FB layout can be reported as early as
possible.
At the same time move the call to dpu_format_populate_addrs() to
dpu_plane_sspp_atomic_update(). This way the all layout management is
performed only for the visible planes: the .prepare_fb callback is
called for not visible planes too, so keeping dpu_format_populate_addrs

The struct dpu_hw_fmt_layout defines hardware data layout (addresses,
sizes and pitches. Drop format field from this structure as it's not a
part of the data layout.

The DPU driver isn't expected to be used without an IOMMU. Thus the
aspace will be always present. Not to mention that mdp4/mdp5 drivers
call msm_framebuffer_iova() without such checks, as the whole
msm_framebuffer layer is expected to support both IOMMU and IOMMU-less
configurations.
Drop these useless if (aspace) checks.

The dpu_plane_prepare_fb() already calls dpu_format_populate_layout().
Store the generated layout in the plane state and drop this call from
dpu_plane_sspp_update().

Add support for MSM8996, which - fun fact - was the SoC that this driver
(or rather SDE, its downstream origin) was meant for and first tested on.
It has some hardware that differs from the modern SoCs, so not a lot of
current structs could have been reused. It's also seemingly the only SoC
supported by DPU that uses RGB pipes.
Note, by default this platform is still handled by the MDP5 driver
unless the `msm.prefer_mdp5=false' parameter is provided.
