i.MX95 System Manager uses interrupt driven communication which requires
the caller to set Bit[0] of channel flags to 1. When transmission
completes and the previous general purpose interrupt has been processed
by the other core, i.MX95 System Manager will set General Purpose
Interrupt Control Register (GCR). U-Boot polls General-purpose Status
(GSR) to check if the operation is finished.

Add support for the LCD interfaces (LCDIF1/2). When probed, these
interfaces request numerous clocks and power domains, attach the bridge
and look for a panel in order to retrieve its capabilities and
properties.
There is a similar existing driver in the upper folder for other i.MX
targets, I discovered this driver a bit late. It is not targeting the
i.MX8MP and I have no idea how different can the LCDIF be on this SoC,
but I did not manage to get it work, especially because it is not fully
compliant with the device-model, especially on the clocks/power
management side which is all ad-hoc. This is normal though, it was
contributed more than ten years ago.

Add support for the LVDS Display Bridge (LDB) found on i.MX8MP.
When attached, the bridge driver looks for panels connected to one of
its two outputs and adapts its own configuration to use them. There is
currently no support for merged/split displays.
Note regarding the clock configuration:
The LDB output clock should be absolutely identical to the LCDIF output
clock so both blocks can talk to each other synchronously. However, the
LDB clock has an internal divisor of 7 (respectively 3.5 in dual
configuration) which means the LDB input clock must be explicitly set
once we know the configuration.
This driver was tested on i.MX8MP using a single panel connected to the
LVDS2 interface.

Reparenting a clock C with a new parent P means that C will only
continue clocking if P is already clocking when the mux is updated. In
case the parent is currently disabled, failures (stalls) are likely to
happen.
This is exactly what happens on i.MX8 when enabling the video
pipeline. We tell LCDIF clocks to use the VIDEO PLL as input, while the
VIDEO PLL is currently off. This all happens as part of the
assigned-clocks handling procedure, where the reparenting happens before
the enable() calls. Enabling the parents as part of the reparenting
procedure seems sane and also matches the logic applied in other parts
of the CCM.

It is very surprising that such an uclass, specifically designed to
handle resources that may be shared by different devices, is not keeping
the count of the number of times a power domain has been
enabled/disabled to avoid shutting it down unexpectedly or disabling it
several times.
Doing this causes troubles on eg. i.MX8MP because disabling power
domains can be done in recursive loops were the same power domain
disabled up to 4 times in a row. PGCs seem to have tight FSM internal
timings to respect and it is easy to produce a race condition that puts
the power domains in an unstable state, leading to ADB400 errors and
later crashes in Linux.
CI tests using power domains are slightly updated to make sure the count
of on/off calls is even and the results match what we *now* expect.
As we do not want to break existing users while stile getting
interesting error codes, the implementation is split between:
- a low-level helper reporting error codes if the requested transition
could not be operated,
- a higher-level helper ignoring the "non error" codes, like EALREADY and
EBUSY.

There are already several helpers to find a udevice based on its
position in a device tree, like getting a child or a node pointed by a
phandle, but there was no support for graph endpoints, which are very
common in display pipelines.
Add a new helper, named uclass_get_device_by_endpoint() which enters the
child graph reprensentation, looks for a specific port, then follows the
remote endpoint, and finally retrieves the first parent of the given
uclass_id.
This is a very handy and straightforward way to get a bridge or a panel
handle.

Caleb Connolly <caleb.connolly@linaro.org> says:
SCSI devices like UFS may maintain their own cache to speed up writes,
however this is lost on board reset (and may be lost on device removal
or reset by OS drivers).
Currently this can be worked around by "waiting for a while" after
writing data to disk, but of course this is not an acceptable solution.
Ideally U-Boot would have a mechanism to flush caches during board
reset, but until that logic is hooked up let's be sure that all writes
are actually propagated to the storage device so that we don't lose data
on board reset.
The same logic was already implemented just for the AHCI backend, this
duplicated logic has been removed and support for the SYNC_CACHE command
is added to AHCI.
This is particularly noticeable during capsule updates, since the update
file is deleted and the board is reset immediately afterwards which
resulted in the same capsule update being applied over and over again.
This specifically fixes Qualcomm SDM845 devices with UFS 2.1, but likely
all UFS devices that use a cache.
Link: https://lore.kernel.org/r/20250326-scsi-sync-on-write-v2-0-12ab05bd464b@linaro.org
The SCSI layer now issues a SYNC_CACHE command after every write to
ensure there is no data loss due to a board reset after write.
Implement support for this command and remove the same logic from the
ATA write path to be consistent with other SCSI backends.
Ranges are not supported and the whole cache will be flushed in all
cases.
This was done per iteration in ata_scsiop_read_write(), but it's not
clear why this was the case, calling it once for the entire write ought
to achieve the same result.

We don't have a mechanism to safely shutdown block devices prior to a
baord reset or driver removal. Prevent data loss by synchronizing the
SCSI cache after every write.
In particular this solves the issue of capsule updates looping on some
devices because the board resets immediately after deleting the capsule
file and this write wouldn't be flushed in time.
This may impact NAND wear, but should be negligible given the usecases
for disk write in U-Boot.
