Currently the AXP chip requires to have its IRQ line connected to some
interrupt controller, and will fail probing when this is not the case.
On a new Allwinner SoC (H616) there is no NMI pin anymore, and at
least one board does not connect the AXP's IRQ pin to anything else,
so the interrupt functionality of the AXP chip is simply not available.
Check whether the interrupt line number returned by the platform code is
valid, before trying to register the irqchip. If not, we skip this
registration, to avoid the driver to bail out completely.
Also we need to skip the power key functionality, as this relies on
a valid IRQ as well.

During more massive generation of interrupts, the IRQ got stuck,
and the subdevices did not see any new interrupts. That happens
especially at wonky USB supply in combination with ADC reads.
To fix that trigger the IRQ at level low instead of falling edge.

The commit 529a1101212a("mfd: syscon: Don't free allocated name
for regmap_config") doesn't free the allocated name field of struct
regmap_config, but introduce a memory leak. There is another
commit 94cc89eb8fa5("regmap: debugfs: Fix handling of name string
for debugfs init delays") fixing this debugfs init issue from root
cause. With this fixing, the name field in struct regmap_debugfs_node
is removed. When initialize debugfs for syscon driver, the name
field of struct regmap_config is not used anymore. So, the allocated
name field of struct regmap_config is need to be freed directly after
regmap initialization to avoid memory leak.

Currently the software node is removed in error case and at ->remove()
stage unconditionally, that ruins the symmetry. Besides, in some cases,
when mfd_add_device() fails, the device_remove_software_node() call
may lead to NULL pointer dereference:

Add compatible strings and interrupts for pmic keys

MT6358 has two interrupts per key: one for press, another one for

Some pmics of the mt6397 family (such as MT6358), have two IRQs per
physical key: one for press event, another for release event.
The mtk-pmic-keys driver assumes that each key only has one
IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping.
This won't work for MT6358, as we have multiple resources (2) for one key.
To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name
instead of by index.
Note: The keys_resources are not part of the device-tree bindings so
this won't break any DT schemas.

Commit b9d79e4ca4ff ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between
the "struct" keyword and the structure name.
It's a wonder that gcc accepts that silently, but clang quite reasonably
warns about it:

static const struct __maybe_unused seq_operations proc_fb_seq_ops = {

Pull scheduler fixes from Thomas Gleixner:
"A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup
move.
A recent commit combined two PSI callbacks to reduce the number of

cgroup_move_task() which then observes half updated state.
The fix is to solely use task::ps_flags instead of looking at the
potentially mismatching scheduler state

division which can lead to an off-by-one error exceeding the
buckets array size.
- Prevent unfairness caused by missing load decay when a task is
