The macro CLOCKSOURCE_OF_DECLARE was renamed more TIMER_OF_DECLARE, and we
kept an alias CLOCKSOURCE_OF_DECLARE in order to smooth the transition for
drivers.
This change was done 1.5 year ago, we can reasonably remove this backward
compatible macro as it is no longer used anywhere.

The driver seems to abuse *unsigned long* not only for the (32-bit)
register values but also for the 'sh_cmt_channel::total_cycles' which
needs to always be 64-bit -- as a result, the clocksource's mask is
needlessly clamped down to 32-bits on the 32-bit machines...

It's not obvious how the code prevents adding more than 31 elements to

find_lock_lowest_rq may or not releease rq lock when return
lowest_rq=NULL, but it is fuzzy.
If not releasing rq lock, it is unnecessary to re-call

we'll try to use "default" policy node, then, if that doesn't exist,
we'll pick the first node, in order of creation. If that also fails,
we'll allocate M/C range from the beginning of the device's M/C range.

This adds support for CLOCKSYNC SyS-T packets, that establish correlation
between the transport clock (STP timestamps) and SyS-T timestamps. These
packets are sent periodically to allow the decoder to keep both time
sources in sync.

This adds support for MIPI SyS-T protocol as specified in an open
standard [1]. In addition to marking message boundaries, it also
supports tagging messages with the source UUID, to provide better
distinction between trace sources, including payload length and
timestamp in the message's metadata.
This adds a helper to paste 2 pointer arrays together, useful for merging
various types of attribute arrays. There are a few places in the kernel
tree where this is open coded, and I just added one more in the STM class.
The naming is inspired by memset_p() and memcat(), and partial credit for
it
Instead of a local copy, use the memcat_p() helper to merge policy
node attributes.

Add a helper to write a sequence of bytes as STP data packets. This
is used by protocol drivers to output their metadata, as well as the
actual data payload.

Now that the default framing protocol is factored out into its own driver,
switch over to using the driver for writing data. To that end, make the
policy code require a valid protocol name (or absence thereof, which is
equivalent to "p_basic").
Also, to make transition easier, make stm class reque
The current naming of stp-policy root type and group ops is confusing,
rename them for better readability.

At the moment, the stm class applies a certain STP framing pattern to
the data as it is written to the underlying STM device. In order to
allow different framing patterns (aka protocols), this patch introduces
the concept of STP protocol drivers, defines data structures and APIs
for the protocol dr
The STP framing pattern that the stm class implicitly applies to the
data payload is, in fact, a protocol. This patch moves the relevant code
out of the stm core into its own driver module.

This patch can be happily dropped, of course, if someone knows a new
