[ Upstream commit ad2091f893bd5dfe2824f0d6819600d120698e9f ]
The Allwinner V3 SoC shares the same base as the V3s but comes with
extra pins and features available. As a result, it has its dedicated
compatible string (already used in device trees), which is added here.

Howerer we allow the WDT driver to omit the stop hook since commit
"d0684c8a93549" ("watchdog: Make stop function optional") and provide
a module parameter for user that controls the WDOG_STOP_ON_REBOOT flag
in commit 9232c80659e94 ("watchdog: Add stop_on_reboot parameter to
control reboot policy"). Together that commits make user potential to
insert a watchdog driver that don't provide a stop hook but with the

on system reboot.

issue.

[ Upstream commit f65607cdbc6b0da356ef5a22552ddd9313cf87a0 ]
When we set up a TDLS station, we set sta->sta.bandwidth solely based
on the capabilities, because the "what's the current bandwidth" check
is bypassed and only applied for other types of stations.
This leads to the unfortunate scenario that the sta->sta.bandwidth is
160 MHz if both stations support it, but we never actually configure
this bandwidth unless the AP is already using 160 MHz; even for wider
bandwidth support we only go up to 80 MHz (at least right now.)
For iwlwifi, this can also lead to firmware asserts, telling us that
we've configured the TX rates for a higher bandwidth than is actually
available due to the PHY configuration.
For non-TDLS, we check against the interface's requested bandwidth,
but we explicitly skip this check for TDLS to cope with the wider BW
case. Change this to
(a) still limit to the TDLS peer's own chandef, which gets factored
into the overall PHY configuration we request from the driver,
and
(b) limit it to when the TDLS peer is authorized, because it's only
factored into the channel context in this case.

[ Upstream commit 52719fce3f4c7a8ac9eaa191e8d75a697f9fbcbc ]
There are three ways pseries_suspend_begin() can be reached:
1. When "mem" is written to /sys/power/state:
kobj_attr_store()
-> state_store()
-> pm_suspend()
-> suspend_devices_and_enter()
-> pseries_suspend_begin()
This never works because there is no way to supply a valid stream id
using this interface, and H_VASI_STATE is called with a stream id of
zero. So this call path is useless at best.
2. When a stream id is written to /sys/devices/system/power/hibernate.
pseries_suspend_begin() is polled directly from store_hibernate()
until the stream is in the "Suspending" state (i.e. the platform is
ready for the OS to suspend execution):
dev_attr_store()
-> store_hibernate()
-> pseries_suspend_begin()
3. When a stream id is written to /sys/devices/system/power/hibernate
(continued). After #2, pseries_suspend_begin() is called once again
from the pm core:
dev_attr_store()
-> store_hibernate()
-> pm_suspend()
-> suspend_devices_and_enter()
-> pseries_suspend_begin()
This is redundant because the VASI suspend state is already known to
be Suspending.
The begin() callback of platform_suspend_ops is optional, so we can
simply remove that assignment with no loss of function.

Fix array names to match assignments for data items and data items
counter in 'mlxplat_mlxcpld_default_items' structure for:
.data = mlxplat_mlxcpld_default_pwr_items_data,
.count = ARRAY_SIZE(mlxplat_mlxcpld_pwr),
and
.data = mlxplat_mlxcpld_default_fan_items_data,
.count = ARRAY_SIZE(mlxplat_mlxcpld_fan),
Replace:
- 'mlxplat_mlxcpld_pwr' by 'mlxplat_mlxcpld_default_pwr_items_data' for
ARRAY_SIZE() calculation.
- 'mlxplat_mlxcpld_fan' by 'mlxplat_mlxcpld_default_fan_items_data'
for ARRAY_SIZE() calculation.

ARM virtual counter supports event stream, it can only trigger an event
when the trigger bit (the value of CNTKCTL_EL1.EVNTI) of CNTVCT_EL0 changes,
so the actual period of event stream is 2^(cntkctl_evnti + 1). For example,
when the trigger bit is 0, then virtual counter trigger an event for every
two cycles.
While we're at it, rework the way we compute the trigger bit position
by making it more obvious that when bits [n:n-1] are both set (with n
being the most significant bit), we pick bit (n + 1).
