This driver adds support for the STM CoreSight IP block, allowing any
system compoment (HW or SW) to log and aggregate messages via a
single entity.
The CoreSight STM exposes an application defined number of channels
called stimulus port.
This patchset adds support for the CoreSight STM IP block.

Introduce config option to set the default value for memory hotplug
onlining policy (/sys/devices/system/memory/auto_online_blocks). The
reason one would want to turn this option on are to have early onlining
for hotpluggable memory available at boot and to not require any userspace
actions to

Some of kernel driver uses the IIO framework to get the sensor
value via ADC or IIO HW driver. The client driver get iio channel
by iio_channel_get_all() and release it by calling
iio_channel_release_all().
Add resource managed version (devm_*) of these APIs so that if client
calls the
Add following APIs in the list of managed resources of IIO:
devm_iio_channel_get()
devm_iio_channel_get_all()
devm_iio_channel_release()
devm_iio_channel_release_all()
