The mv88e6165 family has its global clock in the PTP global
registers. It does not support any form of PTP events. Add a function
to read the clock, fill in an ops structure, and register it with the
two members of the family.

The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Commit 784abe24c9 ("net: Add decrypted field to skb")
introduced a 'decrypted' field that is explicitly copied on skb
copy and clone.
Move it between headers_start[0] and headers_end[0], so that we
don't need to copy it explicitly as it's copied by the memcpy()
in __copy_skb_header().
While at it, drop the assignment in __skb_clone(), it was
already redundant.
This doesn't change the size of sk_buff or cacheline boundaries.
The 15-bits hole before tc_index becomes a 14-bits hole, and
will be again a 15-bits hole when this change is merged with
commit 8b7008620b ("net: Don't copy pfmemalloc flag in
__copy_skb_header()").
v2: as reported by kbuild test robot (oops, I forgot to build
with CONFIG_TLS_DEVICE it seems), we can't use
CHECK_SKB_FIELD() on a bit-field member. Just drop the
check for the moment being, perhaps we could think of some

CP2104 and the ECI interface of CP2105 support further baud rates than
the ones specified in AN205 table 1, and we can use the same equations
as for CP2102N to determine and report back the actual baud rates used.
Note that this could eventually be generalised also to CP2108, which
uses a different base clock. There appears to be an error in the CP2108
equations which needs to be confirmed on actual hardware first however
(specifically, the subtraction of one from the divisor appears to be
incorrect as it introduces larger errors).

Newer cp210x devices support higher line speeds than the older ones
which supported a discrete set of speeds up to 921.6 kbaud.
To support these higher speeds, we have for some time mapped speeds
lower than 1 Mbaud to the speeds supported by older devices, while
allowing the device to pick the closest possible rate for higher speeds
(without trying to guess and report back what rate was actually chosen).
As this implementation can lead to undefined behaviour for older devices
which do not support the higher rates, let's use the later-added
device-type detection to determine the maximum supported speed.
This will also be useful when adding support for cp2102n which can
handle rates up to 3 Mbaud.
As per the data sheets the following maximum speeds are used
cp2101 921.6 kbaud
cp2102/3 1 Mbaud
cp2104/8 2 Mbaud
cp2105
- ECI port 2 Mbaud
- SCI port 921.6 kbaud
while keeping the maximum 2 Mbaud for unknown device types in order to
avoid any regressions.
