This patch introduces a character device interface for the Counter
subsystem. Device information and control is exposed through a standard
set of ioctl commands.
A high-level view of how a count value is passed down from a counter
driver can be exemplified by the following:

Over the past couple years we have noticed some shortcomings with the
Counter sysfs interface. Although useful in the majority of situations,
there are certain use-cases where interacting through sysfs attributes
can become cumbersome and inefficient. A desire to support more advanced

The system might go into suspend during recovery of any remoteproc.
This will interrupt the recovery process in between increasing the
recovery time. Make the platform device as wakeup capable and
use pm_stay_wake/pm_relax APIs to avoid system from going into
suspend during recovery.

As described in the big comment in the patch, earlycon initialization
can be deferred if, a) earlycon was supplied without arguments and, b)
the ACPI SPCR table hasn't yet been parsed.
Unfortunately, if deferred, then the earlycon is not ready during early
parameter parsing so kgdboc cannot use

There could be a scenario where f2fs_sync_node_pages gets
called during checkpoint, which in turn tries to flush
inline data and calls iput(). This results in deadlock as
iput() tries to hold cp_rwsem, which is already held at the
beginning by checkpoint->block_operations().

I think the original logic was if debugging, you'd see the load-time value in
