Due to the platform's new project uart ip upgrade,
the new project's timeout interrupt needs to use bit17
while other projects' timeout interrupt needs to use
bit13, using private data to adapt and be compatible
with all projects.

Function pl011_throttle_rx() calls pl011_stop_rx() to disable RX, which
also disables the RX DMA by clearing the RXDMAE bit of the DMACR
register. However, to properly unthrottle RX when DMA is used, the
function pl011_unthrottle_rx() is expected to set the RXDMAE bit of
the DMACR register, which it currently lacks. This causes RX to stall
after the throttle API is called.
Set RXDMAE bit in the DMACR register while unthrottling RX if RX DMA is
used.

Commit 7c0cca7c847e ("tty: ldisc: add sysctl to prevent autoloading of
ldiscs") introduces the tty_ldisc_autoload sysctl with the wrong
proc_handler. .extra1 and .extra2 parameters are set to avoid other values
thant SYSCTL_ZERO or SYSCTL_ONE to be set but proc_dointvec do not uses
them.
This commit fixes this by using proc_dointvec_minmax instead of
proc_dointvec.

Complex Dies (CCDs) and enlarged L3 cache, enabling dynamic mode
switching between Frequency and Cache modes. To optimize performance,
implement the AMD 3D V-Cache Optimizer, which allows selecting either:
Frequency mode: cores within the faster CCD are prioritized before
those in the slower CCD.
Cache mode: cores within the larger L3 CCD are prioritized before
those in the smaller L3 CCD.

The current "measurement_chars" CHPID sysfs attribute exposes only a
limited, validity-filtered portion of data from the associated Channel-
Measurements Characteristics Block (CMCB). New machine models add data
that is relevant for userspace tooling to the "header"-portion of the
CMCB. This data that is not currently accessible to userspace.
To prevent having to add new sysfs attributes whenever a new bit of data
is added to the CMCB "header", add a new sysfs attribute named
"measurement_chars_full" that exposes the full, unfiltered CMCB.

The device reset assert and deassert length was created by usleep_range()
but that does not ensure optimal handling of all the different values from
device tree properties. By switching to the new flexible sleeping helper
function, fsleep(), the correct delay function is called depending on
delay length, e.g. udelay(), usleep_range() or msleep().
While at it, move out GPIO consumer name setting of the reset conditional,
the all necessary checks are already done there, so logically that call is
not related to the reset sequence.

of_find_compatible_node() increments the node's refcount, and it must be
decremented again with a call to of_node_put() when the pointer is no
longer required to avoid leaking the resource.
Instead of adding the missing calls to of_node_put() in all execution
paths, use the cleanup attribute for 'arm_timer' by means of the
__free() macro, which automatically calls of_node_put() when the
variable goes out of scope.

In a multi-cluster MIPS system, there are multiple GICs - one in each
cluster - each of which has its independent counter. The counters in
each GIC are not synchronized in any way, so they can drift relative
to one another through the lifetime of the system. This is problematic
for a clock source which ought to be global.
Avoid problems by always accessing cluster 0's counter, using
cross-cluster register access. This adds overhead so it is applied only
on multi-cluster systems.

The sp804 is currently only user selectable if COMPILE_TEST, this was
done by commit dfc82faad725 ("clocksource/drivers/sp804: Add
COMPILE_TEST to CONFIG_ARM_TIMER_SP804") in order to avoid it being
spuriously offered on platforms that won't have the hardware since it's
generally only seen on Arm based platforms. This config is overly
restrictive, while platforms that rely on the SP804 do select it in
their Kconfig there are others such as the Arm fast models which have a
SP804 available but currently unused by Linux. Relax the dependency to
allow it to be user selectable on arm and arm64 to avoid surprises and
in case someone comes up with a use for extra timer hardware.

"
The representee's link state is controlled through the
representor. Setting the representor administratively UP
or DOWN should cause carrier ON or OFF at the representee.
"
This patch enables
- Reflecting the link state of representor based on the VF state and
link state of VF based on representor.
- On VF interface up/down a notification is sent via mbox to representor
to update the link state.
eg: ip link set eth0 up/down will disable carrier on/off
of the corresponding representor(r0p1) interface.
- On representor interface up/down will cause the link state update of VF.
eg: ip link set r0p1 up/down will disable carrier on/off
of the corresponding representee(eth0) interface.
