Booting 6.16 on the Macchiatobin, I discover that I can no longer
access my disks, and thus the userspace boot fails. The cause appears
to be that one of the SATA controllers doesn't have any ports:
[ 1.190312] ahci f4540000.sata: supply ahci not found, using dummy regulator
[ 1.196255] ahci f4540000.sata: supply phy not found, using dummy regulator
[ 1.202026] ahci f4540000.sata: No port enabled
This is as a result of the blamed commit below which added a default
disabled status to the .dtsi, but didn't properly update the mcbin
dtsi file. Fix this regression.

This commit corrects the typo for the right channel, changing the

Current dma-buf vmap semantics require that the mapped buffer remains
in place until the corresponding vunmap has completed.
For GEM-SHMEM, this used to be guaranteed by a pin operation while creating
an S/G table in import. GEM-SHMEN can now import dma-buf objects without
creating the S/G table, so the pin is missing. Leads to page-fault errors,
such as the one shown below.

In this stack strace, udl (based on GEM-SHMEM) imported and vmap'ed a
dma-buf from amdgpu. Amdgpu relocated the buffer, thereby invalidating the
mapping.
Provide a custom dma-buf vmap method in amdgpu that pins the object before
mapping it's buffer's pages into kernel address space. Do the opposite in
vunmap.
Note that dma-buf vmap differs from GEM vmap in how it handles relocation.
While dma-buf vmap keeps the buffer in place, GEM vmap requires the caller
to keep the buffer in place. Hence, this fix is in amdgpu's dma-buf code
instead of its GEM code.
A discussion of various approaches to solving the problem is available
at [1].

- try (GTT | VRAM); drop CPU domain (Christian)

- only use mapable domains (Christian)

Use the modern PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

Add infrastructure to handle regulator undervoltage events for MMC/eMMC
cards. When an undervoltage is detected, the new handler performs a
controlled emergency suspend using a short power-off notification,
skipping the cache flush to maximize the chance of a safe shutdown.
After the operation, the card is marked as removed to prevent further
I/O and possible data corruption.
This is implemented by introducing MMC_POWEROFF_UNDERVOLTAGE to the
mmc_poweroff_type enum and refactoring the suspend logic into an
internal __mmc_suspend() helper that allows the caller to skip the cache
flush if required. The undervoltage handler is registered as a bus
operation and invoked from the core undervoltage path.
If power-off notification is not supported by the card, the handler
falls back to sleep or deselecting the card.
Additionally, update the shutdown path to avoid redundant shutdown
steps if the card is already removed

Implement the core infrastructure to allow MMC bus types to handle
REGULATOR_EVENT_UNDER_VOLTAGE events from power regulators. This is
primarily aimed at allowing devices like eMMC to perform an emergency
shutdown to prevent data corruption when a power failure is imminent.
This patch introduces:
- A new 'handle_undervoltage' function pointer to 'struct mmc_bus_ops'.
Bus drivers (e.g., for eMMC) can implement this to define their
emergency procedures.
- A workqueue ('uv_work') in 'struct mmc_supply' to handle the event
asynchronously in a high-priority context.
- A new function 'mmc_handle_undervoltage()' which is called from the
workqueue. It stops the host queue to prevent races with card removal,
checks for the bus op, and invokes the handler.
- Functions to register and unregister the regulator notifier, intended
to be called by bus drivers like 'mmc_attach_mmc' when a compatible
card is detected.
The notifier is only registered for the main vmmc supply, as
undervoltage handling for vqmmc or vqmmc2 is not required at this
time.
