Greetings,
This is v3 of the patchset that adds support to the optional
divider_by_two of LRADC channels.
Changes in v3:
- Fix merge conflict with previous existing patch.
- Fix ampersand in function callback assignment.
- Removed unused parameters of function to read single sample.
- Ennumerati
Some LRADC channels have fixed pre-dividers and all have an optional
divider by two which allows a maximum input voltage of VDDIO - 50mV.
This patch

- grabs the max reference voltage per channel from DT
(where the fixed pre-dividers apply)
- allow
Some LRADC channels have fixed pre-dividers so they can measure
different voltages at full scale. The reference voltage allows to
expose a scaling attribute through the IIO sysfs so that a user can
compute the real voltage out of a measured sample value.

The LRADC virtual channels have an 18 bit field to store the sum of up
to 2^5 accumulated samples. The read_raw function however only operates
over a single sample (12 bit resolution).
In order to use this field for scaling operations, we need it to be the
exact resolution value of the LRADC.
Besid
Added write_raw function to manipulate the optional divider_by_two
through the scaling attribute out of the available scales.

Every "file_operations" used by tracing_init_debugfs_percpu is buggy.

Currently you have to known that mem-loads is a PEBS event

After the previous changes trace_array_cpu->trace_cpu and
trace_array->trace_cpu becomes write-only. Remove these members
and kill "struct trace_cpu" as well.
As a side effect this also removes memset(per_cpu_memory, 0).

If gcc and python are not under the standard path, it could cause

Currently different drivers requiring to access cpu device node are
parsing the device tree themselves. Since the ordering in the DT need
not match the logical cpu ordering, the parsing logic needs to consider
that. However, this has resulted in lots of code duplicatio

Currently the topology code computes cpu capacity and stores it in
the list along with hwid(which is MPIDR) as it parses the CPU nodes
in the device tree. This is required as it needs to be mapped to the
logical CPU later.

Currently set_secondary_cpus_clock assume the CPU logical ordering
and the MPDIR in DT are same, which is incorrect.
Since the CPU device nodes can be retrieved in the logical ordering
using the DT helper, we can remove the devices tree parsing.

Since the CPU device nodes can be retrieved using arch_of_get_cpu_node,
we can use it to avoid parsing the cpus node searching the cpu nodes and
mapping to logical index.
This patch removes parsing DT for cpu nodes by using of_get_cpu_node.

Now that the cpu device registration initialises the of_node(if available)
appropriately for all the cpus, parsing here is redundant.
This patch removes all DT parsing and uses cpu->of_node instead.

OF/DT core library now provides architecture specific hook to match the
logical cpu index with the corresponding physical identifier. Most of the
cpu DT node parsing and initialisation is contained in devtree.c. So it's
better to define ARM specific arch_match_cpu_phys

Multiple drivers need to get the cpu device node from the cpu logical
index and then access the of_node.
This patch adds helper function to fetch the device node directly.

As more and more information is getting added into the cpu node, the number
of drivers needing to parse the device tree for CPU nodes are increasing.
Most of the time, the information needed from the cpu node is preferred
in the logical CPU order. Hence many drivers fi
It was observed that if order is passed as more than MAX_ORDER
allocation in __alloc_pages_nodemask, it will unnecessarily go to
slowpath and then return failure.
Since we know that more than MAX_ORDER will anyways fail, we can
avoid slowpath by returning failure in nodemask itself.

Few control settings done in architected timer as part of initialisation
can be lost when CPU enters deeper power states. They need to be
re-initialised when the CPU is (warm)reset again.
This patch adds CPU PM notifiers to do the timer initialisation on warm
resets.
From: Will Deacon
The ARM architected timer can generate events (used for waking up
CPUs executing the wfe instruction) at a frequency represented as a
power-of-2 divisor of the clock rate.
This patch configures the event stream, aiming for a period of 100us
between events. This can be used to i
