[ Upstream commit b78ac6ecd1b6b46f8767cbafa95a7b0b51b87ad8 ]
Allow the configuration of the MDIO clock divider when the Device Tree
contains 'clock-frequency' property (similar to I2C and SPI buses).
Because the hardware may have lost its state during suspend/resume,
re-apply the MDIO clock divider upon resumption.

following commit:
commit d58e468b1112 ("flow_dissector: implements flow dissector BPF hook")
added struct bpf_flow_keys which conflicts with the struct with
same name in sockex2_kern.c and sockex3_kern.c
similar to commit:
commit 534e0e52bc23 ("samples/bpf: fix a compilation failure")
we tried the rename it "flow_keys" but it also conflicted with struct
having same name in include/net/flow_dissector.h. Hence renaming the
struct to "flow_key_record". Also, this commit doesn't fix the
compilation error completely because the similar struct is present in
sockex3_kern.c. Hence renaming it in both files sockex3_user.c and
sockex3_kern.c

This is a workaround for FW bug -
MFW generates bandwidth attention in single function mode, which
is only expected to be generated in multi function mode.
This undesired attention in SF mode results in incorrect HW

With introduction of MC-aware mode to mlxsw, it became necessary to
configure TCs above 7 as well. There is now code in mlxsw to disable ETS
for these higher classes, but disablement of max shaper was neglected.
By default, max shaper is currently disabled to begin with, so the
problem is just cosmetic. However, for symmetry, do like we do for ETS
configuration, and call mlxsw_sp_port_ets_maxrate_set() for both TC i
and i + 8.

The function of genphy_read_status is that reading phy information
from HW and using these information to update SW variable. If user
is using ethtool to setting the speed of phy and service task is calling
by hclge_get_mac_phy_link, the result of speed setting is uncertain.
Because ethtool cmd will modified phydev and hclge_get_mac_phy_link also
will modified phydev.
Because phy state machine will update phy link periodically, we can
just use phydev->link to check the link status. This patch removes
function call of genphy_read_status. To ensure accuracy, this patch
adds a phy state check. If phy state is not PHY_RUNNING, we consider
link is down. Because in some scenarios, phydev->link may be link up,
but phy state is not PHY_RUNNING. This is just an intermediate state.
In fact, the link is not ready yet.

When performing partition migrations all present CPUs must be online
as all present CPUs must make the H_JOIN call as part of the migration
process. Once all present CPUs make the H_JOIN call, one CPU is returned
to make the rtas call to perform the migration to the destination system.
During testing of migration and changing the SMT state we have found
instances where CPUs are offlined, as part of the SMT state change,
before they make the H_JOIN call. This results in a hung system where
every CPU is either in H_JOIN or offline.
To prevent this this patch disables CPU hotplug during the migration
process.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, also the implementation in this
driver has returns 'netdev_tx_t' value, so just change the function
return type to netdev_tx_t.

Looking at logs from systems all over the place, it looks like tons
of broken systems exist that set the base address to zero. I can
only guess that is some sort of non-standard idea to mark the
interface as not being present. It can't be zero, anyway, so just
complain and ignore it.

Mediatek SPI driver modifies some fields (tx_buf, rx_buf, len, tx_dma,
rx_dma) of the spi_transfer* passed in when doing transfer_one and in
interrupt handler. This is somewhat unexpected, and there are some
caller (e.g. Cr50 spi driver) that reuse the spi_transfer for multiple
messages. Add a field to record how many bytes have been transferred,
and calculate the right len / buffer based on it instead.

Commit d58e468b1112d ("flow_dissector: implements flow dissector BPF hook")
introduced struct bpf_flow_keys in include/uapi/linux/bpf.h and hence
caused the naming conflict with samples/bpf/sockex3_user.c.
The fix is to rename struct bpf_flow_keys in samples/bpf/sockex3_user.c
to flow_keys to avoid the conflict.

On the error path of mxs_auart_request_gpio_irq() is performed
backward iterating with index i of enum type. Underline enum type
may be unsigned char. In this case check (--i >= 0) will be always
true and error handling goes into infinite loop.
The patch changes the check so that it is valid for signed and unsigned
types.

The driver's suspend/resume functions were buggy.
If UART node contains any child node in the DT and
the child is established a communication path with
the parent UART. The relevant /dev/ttyPS* node will
be not available for other operations.
If the driver is trying to do any operations like
suspend/resume without checking the tty->dev status
it leads to the kernel crash/hang.
This patch fix this issue by call the device_may_wake()
with the generic parameter of type struct device.
in the uart suspend and resume paths.
It also fixes a race condition in the uart suspend
path(i.e uart_suspend_port() should be called at the
end of cdns_uart_suspend API this path updates the same)

[ Upstream commit 4d19db777a2f32c9b76f6fd517ed8960576cb43e ]
Calling napi_schedule() from process context does not ensure that the
NET_RX softirq is run in a timely fashion. So trigger it manually.
This is no big issue with current code. A call to ndo_open() is usually
followed by a ndo_set_rx_mode() call, and for qeth this contains a
spin_unlock_bh(). Except for OSN, where qeth_l2_set_rx_mode() bails out
early.
Nevertheless it's best to not depend on this behaviour, and just fix
the issue at its source like all other drivers do. For instance see
commit 83a0c6e58901 ("i40e: Invoke softirqs after napi_reschedule").

mode interface") but accidentally missed part of the locking change.
The lock has to be held earlier so that we're holding it when we do
"sc->tx99_vif = vif;" and also there in the current code there is a
stray unlock before we have taken the lock.

lpss_iosf_enter_d3_state() checks if all hw-blocks using the DMA
controllers are in d3 before powering down the DMA controllers.
But on devices, where the I2C bus connected to the PMIC is shared by
the PUNIT, the controller for that bus will never reach d3 since it has
an effectively empty _PS3 method. Instead it appears to automatically
power-down during S0i3 and we never see it as being in d3.
This causes the DMA controllers to never be powered-down on these devices,
causing them to never reach S0i3. This commit uses the ACPI _SEM method
to detect if an I2C bus is shared with the PUNIT and if it is, it removes
it from the mask of devices which lpss_iosf_enter_d3_state() checks for.
This fixes these devices never reaching any S0ix states.

The terminating NUL byte is only there because the buffer is
allocated with kzalloc(PAGE_SIZE, GFP_KERNEL), but since the
range-check is off-by-one, and PAGE_SIZE==PATH_MAX, the
returned string may not be zero-terminated if it is exactly
PATH_MAX characters long. Furthermore also the initial loop
may theoretically exceed PATH_MAX and cause a fault.

During component_bind_all(), if bind() fails for any
particular component associated with a master, unbind()
should be called for all previous components in that
master's match array, whose bind() might have completed
successfully. As per the current logic, if bind() fails
for the component at position 'n' in the master's match
array, it would start calling unbind() from component in
'n'th position itself and work backwards, and will always
skip calling unbind() for component in 0th position in the
master's match array.
Fix this by updating the loop condition, and the logic to
refer to the components in master's match array, so that
unbind() is called for all components starting from 'n-1'st
position in the array, until (and including) component in
0th position.
