In 69de4421bb4c ("drm/ttm: Initialize debugfs from
ttm_global_init()"), ttm_global_init was changed so that if creation
of the debugfs global root directory fails, ttm_global_init will bail
out early and return an error, leading to initialization failure of
DRM drivers. However, not every system will be using debugfs. On such
a system, debugfs directory creation can be expected to fail, but DRM
drivers must still be usable. This changes it so that if creation of
TTM's debugfs root directory fails, then no biggie: keep calm and
carry on.
Fixes: 69de4421bb4c ("drm/ttm: Initialize debugfs from ttm_global_init()")

Reading status register can fail in the interrupt handler. In such
case, the regmap_read() will not store anything useful under passed
'val' variable and random stack value will be used to determine type of
interrupt.
Handle the regmap_read() failure to avoid handling interrupt type and
triggering changed power supply event based on random stack value.

Adding generic ethtool per-queue statistic framework to display the
statistics for each rx/tx queue. In future, users can avail it to add
more per-queue specific counters. Number of rx/tx queues displayed is
depending on the available rx/tx queues in that particular MAC config
and this number is limited up to the MTL_MAX_{RX|TX}_QUEUES defined
in the driver.
Ethtool per-queue statistic display will look like below, when users
start adding more counters.
Example:
q0_tx_statA:
q0_tx_statB:
q0_tx_statC:

q0_tx_statX:

Each completion ring entry has a valid bit to indicate that the entry
contains a valid completion event. The driver's main poll loop
__bnxt_poll_work() has the proper dma_rmb() to make sure the valid
bit of the next entry has been checked before proceeding further.
But when we call bnxt_rx_pkt() to process the RX event, the RX
completion event consists of two completion entries and only the
first entry has been checked to be valid. We need the same barrier
after checking the next completion entry. Add missing dma_rmb()
barriers in bnxt_rx_pkt() and other similar locations.

The sja1105 driver's initialization and teardown sequence is a chaotic
mess that has gathered a lot of cruft over time. It works because there
is no strict dependency between the functions, but it could be improved.
The basic principle that teardown should be the exact reverse of setup
is obviously not held. We have initialization steps (sja1105_tas_setup,
sja1105_flower_setup) in the probe method that are torn down in the DSA
.teardown method instead of driver unbind time.
We also have code after the dsa_register_switch() call, which implicitly
means after the .setup() method has finished, which is pretty unusual.
Also, sja1105_teardown() has calls set up in a different order than the
error path of sja1105_setup(): see the reversed ordering between
sja1105_ptp_clock_unregister and sja1105_mdiobus_unregister.
Also, sja1105_static_config_load() is called towards the end of
sja1105_setup(), but sja1105_static_config_free() is also towards the
end of the error path and teardown path. The static_config_load() call
should be earlier.
Also, making and breaking the connections between struct sja1105_port
and struct dsa_port could be refactored into dedicated functions, makes
the code easier to follow.
We move some code from the DSA .setup() method into the probe method,
like the device tree parsing, and we move some code from the probe
method into the DSA .setup() method to be symmetric with its placement
in the DSA .teardown() method, which is nice because the unbind function
has a single call to dsa_unregister_switch(). Example of the latter type
of code movement are the connections between ports mentioned above, they
are now in the .setup() method.
Finally, due to fact that the kthread_init_worker() call is no longer
in sja1105_probe() - located towards the bottom of the file - but in
sja1105_setup() - located much higher - there is an inverse ordering
with the worker function declaration, sja1105_port_deferred_xmit. To
avoid that, the entire sja1105_setup() and sja1105_teardown() functions
are moved towards the bottom of the file.

The felix DSA driver, which is a wrapper over the same hardware class as
ocelot, is integrated with phylink, but ocelot is using the plain PHY
library. It makes sense to bring together the two implementations, which
is what this patch achieves.
This is a large patch and hard to break up, but it does the following:
The existing ocelot_adjust_link writes some registers, and
felix_phylink_mac_link_up writes some registers, some of them are
common, but both functions write to some registers to which the other
doesn't.
The main reasons for this are:
- Felix switches so far have used an NXP PCS so they had no need to
write the PCS1G registers that ocelot_adjust_link writes
- Felix switches have the MAC fixed at 1G, so some of the MAC speed
changes actually break the link and must be avoided.
The naming conventions for the functions introduced in this patch are:
- vsc7514_phylink_{mac_config,validate} are specific to the Ocelot
instantiations and placed in ocelot_net.c which is built only for the
ocelot switchdev driver.
- ocelot_phylink_mac_link_{up,down} are shared between the ocelot
switchdev driver and the felix DSA driver (they are put in the common
lib).
One by one, the registers written by ocelot_adjust_link are:
DEV_MAC_MODE_CFG - felix_phylink_mac_link_up had no need to write this
register since its out-of-reset value was fine and
did not need changing. The write is moved to the
common ocelot_phylink_mac_link_up and on felix it is
guarded by a quirk bit that makes the written value
identical with the out-of-reset one
DEV_PORT_MISC - runtime invariant, was moved to vsc7514_phylink_mac_config
PCS1G_MODE_CFG - same as above
PCS1G_SD_CFG - same as above
PCS1G_CFG - same as above
PCS1G_ANEG_CFG - same as above
PCS1G_LB_CFG - same as above
DEV_MAC_ENA_CFG - both ocelot_adjust_link and ocelot_port_disable
touched this. felix_phylink_mac_link_{up,down} also
do. We go with what felix does and put it in
ocelot_phylink_mac_link_up.
DEV_CLOCK_CFG - ocelot_adjust_link and felix_phylink_mac_link_up both
write this, but to different values. Move to the common
ocelot_phylink_mac_link_up and make sure via the quirk
that the old values are preserved for both.
ANA_PFC_PFC_CFG - ocelot_adjust_link wrote this, felix_phylink_mac_link_up
did not. Runtime invariant, speed does not matter since
PFC is disabled via the RX_PFC_ENA bits which are cleared.
Move to vsc7514_phylink_mac_config.
QSYS_SWITCH_PORT_MODE_PORT_ENA - both ocelot_adjust_link and
felix_phylink_mac_link_{up,down} wrote
this. Ocelot also wrote this register
from ocelot_port_disable. Keep what
felix did, move in ocelot_phylink_mac_link_{up,down}
and delete ocelot_port_disable.
ANA_POL_FLOWC - same as above
SYS_MAC_FC_CFG - same as above, except slight behavior change. Whereas
ocelot always enabled RX and TX flow control, felix
listened to phylink (for the most part, at least - see
the 2500base-X comment).
The registers which only felix_phylink_mac_link_up wrote are:
SYS_PAUSE_CFG_PAUSE_ENA - this is why I am not sure that flow control
worked on ocelot. Not it should, since the
code is shared with felix where it does.
ANA_PORT_PORT_CFG - this is a Frame Analyzer block register, phylink
should be the one touching them, deleted.
Other changes:
- The old phylib registration code was in mscc_ocelot_init_ports. It is
hard to work with 2 levels of indentation already in, and with hard to
follow teardown logic. The new phylink registration code was moved
inside ocelot_probe_port(), right between alloc_etherdev() and
register_netdev(). It could not be done before (=> outside of)
ocelot_probe_port() because ocelot_probe_port() allocates the struct
ocelot_port which we then use to assign ocelot_port->phy_mode to. It
is more preferable to me to have all PHY handling logic inside the
same function.
- On the same topic: struct ocelot_port_private :: serdes is only used
in ocelot_port_open to set the SERDES protocol to Ethernet. This is
logically a runtime invariant and can be done just once, when the port
registers with phylink. We therefore don't even need to keep the
serdes reference inside struct ocelot_port_private, or to use the devm
variant of of_phy_get().
- Phylink needs a valid phy-mode for phylink_create() to succeed, and
the existing device tree bindings in arch/mips/boot/dts/mscc/ocelot_pcb120.dts
don't define one for the internal PHY ports. So we patch
PHY_INTERFACE_MODE_NA into PHY_INTERFACE_MODE_INTERNAL.
- There was a strategically placed:
switch (priv->phy_mode) {
case PHY_INTERFACE_MODE_NA:
continue;
which made the code skip the serdes initialization for the internal
PHY ports. Frankly that is not all that obvious, so now we explicitly
initialize the serdes under an "if" condition and not rely on code
jumps, so everything is clearer.
- There was a write of OCELOT_SPEED_1000 to DEV_CLOCK_CFG for QSGMII
ports. Since that is in fact the default value for the register field
DEV_CLOCK_CFG_LINK_SPEED, I can only guess the intention was to clear
the adjacent fields, MAC_TX_RST and MAC_RX_RST, aka take the port out
of reset, which does match the comment. I don't even want to know why
this code is placed there, but if there is indeed an issue that all
ports that share a QSGMII lane must all be up, then this logic is
already buggy, since mscc_ocelot_init_ports iterates using
for_each_available_child_of_node, so nobody prevents the user from
putting a 'status = "disabled";' for some QSGMII ports which would
break the driver's assumption.
In any case, in the eventuality that I'm right, we would have yet
another issue if ocelot_phylink_mac_link_down would reset those ports
and that would be forbidden, so since the ocelot_adjust_link logic did
not do that (maybe for a reason), add another quirk to preserve the
old logic.
The ocelot driver teardown goes through all ports in one fell swoop.
When initialization of one port fails, the ocelot->ports[port] pointer
for that is reset to NULL, and teardown is done only for non-NULL ports,
so there is no reason to do partial teardowns, let the central
mscc_ocelot_release_ports() do its job.
Tested bind, unbind, rebind, link up, link down, speed change on mock-up
hardware (modified the driver to probe on Felix VSC9959). Also
regression tested the felix DSA driver. Could not test the Ocelot
specific bits (PCS1G, SERDES, device tree bindings).

ocelot_port_enable touches ANA_PORT_PORT_CFG, which has the following
fields:
- LOCKED_PORTMOVE_CPU, LEARNDROP, LEARNCPU, LEARNAUTO, RECV_ENA, all of
which are written with their hardware default values, also runtime
invariants. So it makes no sense to write these during every .ndo_open.
- PORTID_VAL: this field has an out-of-reset value of zero for all ports
and must be initialized by software. Additionally, the
ocelot_setup_logical_port_ids() code path sets up different logical
port IDs for the ports in a hardware LAG, and we absolutely don't want
.ndo_open to interfere there and reset those values.
So in fact the write from ocelot_port_enable can better be moved to
ocelot_init_port, and the .ndo_open hook deleted.
ocelot_port_disable touches DEV_MAC_ENA_CFG and QSYS_SWITCH_PORT_MODE_PORT_ENA,
in an attempt to undo what ocelot_adjust_link did. But since .ndo_stop
does not get called each time the link falls (i.e. this isn't a
substitute for .phylink_mac_link_down), felix already does better at
this by writing those registers already in felix_phylink_mac_link_down.
So keep ocelot_port_disable (for now, until ocelot is converted to
phylink too), and just delete the felix call to it, which is not
necessary.

There is a known bug on BCM2711's SDHCI core integration where the
controller will hang when the difference between the core clock and the
bus clock is too great. Specifically this can be reproduced under the
following conditions:
- No SD card plugged in, polling thread is running, probing cards at
100 kHz.
- BCM2711's core clock configured at 500MHz or more.
So set 200 kHz as the minimum clock frequency available for that board.

Remove "bResult" and "tmpchannel" and all tests and assignments that
are related to them in the code of PHY_SwChnl8188E().
"bResult" was always true, therefore its test led to a null statement.
"tmpchannel" was used only to restore "pHalData->CurrentChannel" to its
previous value only if _PHY_SwChnl8192C() was not called; therefore
assign "channel" to "pHalData->CurrentChannel" if and only if
_PHY_SwChnl8192C() is to be executed (and get rid of that temporary
storage).

The current_opp is released only when whole OPP table is released,
otherwise it's only marked as removed by dev_pm_opp_remove_table().
Functions like dev_pm_opp_put_clkname() and dev_pm_opp_put_supported_hw()
are checking whether OPP table is empty and it's not if current_opp is
set since it holds the refcount of OPP, this produces a noisy warning
from these functions about busy OPP table. Remove the checks to fix it.

Pull irq fixes from Thomas Gleixner:
"A set of fixes for PCI/MSI and x86 interrupt startup:
- Mask all MSI-X entries when enabling MSI-X otherwise stale unmasked
entries stay around e.g. when a crashkernel is booted.
- Enforce masking of a MSI-X table entry when updating it, which
mandatory according to speification
- Ensure that writes to MSI[-X} tables are flushed.
- Prevent invalid bits being set in the MSI mask register
- Properly serialize modifications to the mask cache and the mask
register for multi-MSI.
- Cure the violation of the affinity setting rules on X86 during
interrupt startup which can cause lost and stale interrupts. Move
the initial affinity setting ahead of actualy enabling the
interrupt.
- Ensure that MSI interrupts are completely torn down before freeing
them in the error handling case.
- Prevent an array out of bounds access in the irq timings code"

There is no reason to assume that the IRQ rising edge (indicating that
the device start up phase is done) will happen after we request the IRQ.
If the device is already up by the time we request it, the call to
'wait_for_completion_timeout()' will timeout and we will fail the device
probe even though there's nothing wrong.
Fix it by just polling the status register until we get the indication that
the device is up and running. As a side effect of this fix, requesting the
IRQ is also moved to after the setup function.

Commit 41a9ada3e6b4253f ("of/fdt: mark hotpluggable memory") introduced
two (for systems with and without memblock) weak versions of
early_init_dt_mark_hotplug_memory_arch(), that could be overridden by an
architecture-specific version. However, no overrides ever emerged.
Later, commit aca52c3983891060 ("mm: remove CONFIG_HAVE_MEMBLOCK")
removed the non-memblock version.
Remove early_init_dt_mark_hotplug_memory_arch(), and replace it by a
direct call to memblock_mark_hotplug().
