This patch sets both the XPCS and MPCS blocks in reset when they aren't

The Synopsys SSI Controller has an interface clock, but most SoCs hide

Instead of having each psci init function taking care of the of_node_put(),
let's deal with that from psci_dt_init(), as this enables a bit simpler
error path for each psci init function.

Let's split the psci_dt_cpu_init_idle() function into two functions. This
makes the code clearer and provides better re-usability.

Instead of iterating through all the state nodes in DT, to find out how
many states that needs to be allocated, let's use the number already known
by the cpuidle driver. In this way we can drop the iteration altogether.

The files for the PSCI firmware driver were moved to a sub-directory, let's
update MAINTAINERS to reflect that.

Some following changes extends the PSCI driver with some additional new
files. Let's avoid to continue cluttering the toplevel firmware directory
and first move the PSCI files into a PSCI sub-directory.

Please don't move from one deprecated API to another one. If you feel
like cleaning up DMA API calls please move to dma_alloc_coherent,

The Synopsys I2C Controller has an interface clock that some SoCs
require to access the registers. This series also details the new clock
property in the bindings documentation.

instead of "peripheral clock".

From: Phil Edworthy
The Synopsys I2C Controller has an interface clock, but most SoCs hide
this away. However, on some SoCs you need to explicitly enable the
interface clock in order to access the registers. Therefore, add
support for an optional interface clock.

First, we have a race between perf_event_release_kernel() and
perf_free_event(), which happens when parent's event is released while the
child's fork fails (because of a fatal signal, for example), that looks
like this:

Generic register bitfield-based multiplexer that controls the multiplexer
producer defined under a parent node.
The driver corresponding to parent node provides register read/write
capabilities.

Per-patch changelog is missing here, would be good to include that to help
reviewers. I've done a very quick scroll through, looks like a nice&clean

Occasionally, during the disconnection procedure on XenBus which
includes hash cache deinitialization there might be some packets
still in-flight on other processors. Handling of these packets includes
hashing and hash cache population that finally results in hash cache
data structure corruption.
