debug + add rate limiting
A RX overflow usually happens during high system load. Printing
overflow messages to the kernel log, which on embedded systems often
is outputted on the serial console, even increases the system load.
To decrease the system load in these situations, denote the messages
to debug level and wrap them with net_ratelimit().

This patch exchanges the order of open_candev() and
pm_runtime_get_sync(), so that open_candev() is called first.
A usual reason why open_candev() fails is missing CAN bit rate
configuration. It makes no sense to resume the device from PM sleep
first just to put it to sleep if the bit rate is not configured.

In commit 8a5a75e5e9e5 ("of/fdt: Make sure no-map does not remove
already reserved regions") we returned -EBUSY when trying to mark
regions as no-map when they intersect with reserved memory. The goal was
to find bad no-map reserved memory DT nodes that would unmap the kernel
text/data sections.
The problem is the reserved memory check will still trigger if the DT
has a /memreserve/ that completely subsumes the no-map memory carveouts
in the reserved memory node _and_ that region is also not part of the
memory reg property. For example in sc7180.dtsi we have the following
reserved-memory and memory node:
memory@80000000 {
/* We expect the bootloader to fill in the size */
reg = <0 0x80000000 0 0>;
};
smem_mem: memory@80900000 {
reg = <0x0 0x80900000 0x0 0x200000>;
no-map;
};
and the memreserve filled in by the bootloader is
/memreserve/ 0x80800000 0x400000;
while the /memory node is transformed into
memory@80000000 {
/* The bootloader fills in the size, and adds another region */
reg = <0 0x80000000 0 0x00800000>,
<0 0x80c00000 0 0x7f200000>;
};
The smem region is doubly reserved via /memreserve/ and by not being
part of the /memory reg property. This leads to the following warning
printed at boot.
OF: fdt: Reserved memory: failed to reserve memory for node 'memory@80900000': base 0x0000000080900000, size 2 MiB
Otherwise nothing really goes wrong because the smem region is not going
to be mapped by the kernel's direct linear mapping given that it isn't
part of the memory node. Therefore, let's only consider this to be a
problem if we're trying to mark a region as no-map and it is actually
memory that we're intending to keep out of the kernel's direct mapping
but it's already been reserved.

The cells_name field of of_phandle_iterator might be NULL. Use the
phandle name instead. With this change instead of:
OF: /soc/pinctrl@1000000: (null) = 3 found 2
We get:
OF: /soc/pinctrl@1000000: phandle pinctrl@1000000 needs 3, found 2
Which is a more helpful messages making DT debugging easier.
In this particular example the phandle name looks like duplicate of the
same node name. But note that the first node is the parent node
(it->parent), while the second is the phandle target (it->node). They
happen to be the same in the case that triggered this improvement. See

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:
ACPI_CUSTOM_DSDT_FILE
ARC_BUILTIN_DTB_NAME
ARC_TUNE_MCPU

Use the capabilities field to query the device for ENI stats
support.
This replaces the previous method that tried to get the ENI stats
during ena_probe() and used the success or failure as an indication
for support by the device.
Remove eni_stats_supported field from struct ena_adapter. This field
was used for the previous method of queriying for ENI stats support.
Change the severity level of the print in case of
ena_com_get_eni_stats() failure from info to error.
With the previous method of querying form ENI stats support, failure
to get ENI stats was normal for devices that don't support it.
With the use of the capabilities field such a failure is unexpected,
as it is called only if the device reported that it supports ENI
stats.

This bitmask field indicates what capabilities are supported by the
device.
The capabilities field differs from the 'supported_features' field which
indicates what sub-commands for the set/get feature commands are
supported. The sub-commands are specified in the 'feature_id' field of
the 'ena_admin_set_feat_cmd' struct in the following way:
struct ena_admin_set_feat_cmd cmd;
cmd.aq_common_descriptor.opcode = ENA_ADMIN_SET_FEATURE;
cmd.feat_common.feature_
The 'capabilities' field, on the other hand, specifies different
capabilities of the device. For example, whether the device supports
querying of ENI stats.
Also add an enumerator which contains all the capabilities. The
first added capability macro is for ENI stats feature.
Capabilities are queried along with the other device attributes (in
ena_com_get_dev_attr_feat()) during device initialization and are stored
in the ena_com_dev struct. They can be later queried using the
ena_com_get_cap() helper function.

Assuming the test setup described here:
https://patchwork.kernel.org/project/netdevbpf/cover/20210205130240.4072854-1-vladimir.oltean@nxp.com/
(swp1 and swp2 are in bond0, and bond0 is in a bridge with swp0)
it can be seen that when swp1 goes down (on either board A or B), then
traffic that should go through that port isn't forwarded anywhere.
A dump of the PGID table shows the following:
PGID_DST[0] = ports 0
PGID_DST[1] = ports 1

Whereas a "good" PGID configuration for that setup should have looked
like this:
PGID_DST[0] = ports 0
PGID_DST[1] = ports 1, 2
PGID_DST[2] = ports 1, 2
PGID_DST[3] = ports 3

PGID_AGGR[2] = ports 0, 2, 3, 4, 5
PGID_AGGR[3] = ports 0, 2, 3, 4, 5
PGID_AGGR[4] = ports 0, 2, 3, 4, 5
PGID_AGGR[5] = ports 0, 2, 3, 4, 5
PGID_AGGR[6] = ports 0, 2, 3, 4, 5

PGID_SRC[4] = no ports
PGID_SRC[5] = no ports
PGID_SRC[6] = ports 0, 1, 2, 3, 4, 5
In other words, in the "bad" configuration, the attempt is to remove the
inactive swp1 from the destination ports via PGID_DST. But when a MAC
table entry is learned, it is learned towards PGID_DST 1, because that
is the logical port id of the LAG itself (it is equal to the lowest
numbered member port). So when swp1 becomes inactive, if we set
PGID_DST[1] to contain just swp1 and not swp2, the packet will not have
any chance to reach the destination via swp2.
The "correct" way to remove swp1 as a destination is via PGID_AGGR
(remove swp1 from the aggregation port groups for all aggregation
codes). This means that PGID_DST[1] and PGID_DST[2] must still contain
both swp1 and swp2. This makes the MAC table still treat packets
destined towards the single-port LAG as "multicast", and the inactive
ports are removed via the aggregation code tables.
The change presented here is a design one: the ocelot_get_bond_mask()
function used to take an "only_active_ports" argument. We don't need
that. The only call site that specifies only_active_ports=true,
ocelot_set_aggr_pgids(), must retrieve the entire bonding mask, because
it must program that into PGID_DST. Additionally, it must also clear the
inactive ports from the bond mask here, which it can't do if bond_mask
just contains the active ports:
ac = ocelot_read_rix(ocelot, ANA_PGID_PGID, i);
ac &= ~bond_mask; <---- here
/* Don't do division by zero if there was no active
* port. Just make all aggregation codes zero.
*/
if (num_active_ports)
ac |= BIT(aggr_idx[i % num_active_ports]);
ocelot_write_rix(ocelot, ac, ANA_PGID_PGID, i);
So it becomes the responsibility of ocelot_set_aggr_pgids() to take
ocelot_port->lag_tx_active into consideration when populating the
aggr_idx array.

[Why]
To maintain compatibility with firmware older than 4.0.11.
Those firmware may have interrmittent hangs with RDCSPIPE or the PHY,
but we shouldn't regress their previous behavior.
[How]
Use the new path if firmware is development or 4.0.11 or newer. Use the
legacy path otherwise.

[Why]
PSP will suspend and resume DMCUB. Driver should just wait for DMCUB to
finish the auto load before continuining instead of placing it into
reset, wiping its firmware state and reinitializing.
If we don't let DMCUB fully finish initializing for S0ix then some state
will be lost and screen corruption can occur due to incorrect address
translation.
[How]
Use dmub_srv callbacks to determine in DMCUB is running and wait for
auto-load to complete before continuining.
In S0ix DMCUB will be running and DAL fw so initialize will skip.
In S3 DMCUB will not be running and we will do a full hardware init.
In S3 DMCUB will be running but will not be DAL fw so we will also do
a full hardware init.

[why]
1. Current code hard codes link to PHY mapping in dc link level per asic
per revision.
This is not scalable. In long term the mapping will be obatined from
DMUB and store in dc resource.
2. Depending on DCN revision and endpoint type, the definition of
dio_output_idx dio_output_type and phy_idx are not consistent. We need
to unify the meaning of these hardware indices across different system
configuration.
[how]
1. Temporarly move the hardcoded mapping to dc_resource level, which
should have full awareness of asic specific configuration and add a TODO
comment to move the mapping to DMUB.
2. populate dio_output_idx/phy_idx for all configuration, define
usb4_enabled bit instead of dio_output_type as an external enum.

[Why]
Depend on res_pool->res_cap->num_timing_generator to query timing
gernerator information, it would case underflow at the fused display
pipes case.
Due to the res_pool->res_cap->num_timing_generator records default
timing generator resource built in driver, not the current chip.
[How]
Some ASICs would be fused display pipes less than the default setting.
In dcnxx_resource_construct function, driver would obatin real timing
generator count and store it into res_pool->timing_generator_count.
