The SR-IOV spec requires that VFs must report zero for the INTx pin
register as VFs are precluded from INTx support. It's much easier for
the host kernel to understand whether a device is a VF and therefore
whether a non-zero pin register value is bogus than it is to do the
same in userspace. Override the INTx count for such devices and
virtualize the pin register to provide a consistent view of the device
to the user.
As this is clearly a spec violation, warn about it to support hardware
validation, but also provide a known whitelist as it doesn't do much
good to continue complaining if the hardware vendor doesn't plan to
fix it.

When a replicator port is enabled, we block the traffic
on the other port and route all traffic to the new enabled
port. If there are two active trace sessions each targeting
the two different paths from the replicator, the second session
will disable the first session and route all the data to the
second path.
ETR
/
e.g, replicator
\
ETB
If CPU0 is operated in sysfs mode to ETR and CPU1 is operated
in perf mode to ETB, depending on the order in which the
replicator is enabled one device is blocked.
Ideally we need trace-id for the session to make the
right choice. That implies we need a trace-id allocation
logic for the coresight subsystem and use that to route
the traffic. The short term solution is to only manage
the "target port" and leave the other port untouched.
That leaves both the paths unaffected, except that some
unwanted traffic may be pushed to the paths (if the Trace-IDs
are not far enough), which is still fine and can be filtered
out while processing rather than silently blocking the data.

>From the comment in the code, it claims the requirement for byte-address
alignment for RRP register: 'for 32-bit, 64-bit and 128-bit wide trace
memory, the four LSBs must be 0s. For 256-bit wide trace memory, the
five LSBs must be 0s'. This isn't consistent with the program, the
program sets five LSBs as zeros for 32/64/128-bit wide trace memory and
set six LSBs zeros for 256-bit wide trace memory.
After checking with the CoreSight Trace Memory Controller technical
reference manual (ARM DDI 0461B, section 3.3.4 RAM Read Pointer
Register), it proves the comment is right and the program does wrong
setting.
This patch fixes byte-address alignment for RRP by following correct

[ Upstream commit 96a7f64400 ]
Since the ETR could be driven either by SYSFS or by perf, it
becomes complicated how we deal with the buffers used for each
of these modes. The ETR driver cannot simply free the current
attached buffer without knowing the provider (i.e, sysfs vs perf).
To solve this issue, we provide:
1) the driver-mode specific etr buffer to be retained in the drvdata
2) the etr_buf for a session should be passed on when enabling the
hardware, which will be stored in drvdata->etr_buf. This will be
replaced (not free'd) as soon as the hardware is disabled, after
necessary sync operation.
The advantages of this are :
1) The common code path doesn't need to worry about how to dispose
an existing buffer, if it is about to start a new session with a
different buffer, possibly in a different mode.
2) The driver mode can control its buffers and can get access to the
saved session even when the hardware is operating in a different
mode. (e.g, we can still access a trace buffer from a sysfs mode
even if the etr is now used in perf mode, without disrupting the
current session.)
Towards this, we introduce a sysfs specific data which will hold the
etr_buf used for sysfs mode of operation, controlled solely by the
sysfs mode handling code.

We create a coresight trace path for each online CPU when
we start the event. We rely on the number of online CPUs
and then go on to allocate an array matching the "number of
online CPUs" for holding the path and then uses normal
CPU id as the index to the array. This is problematic as
we could have some offline CPUs causing us to access beyond
the actual array size (e.g, on a dual SMP system, if CPU0 is
offline, CPU1 could be really accessing beyond the array).
The solution is to switch to per-cpu array for holding the path.

[ Upstream commit c71369de02 ]
The coresight components could be operated either in sysfs mode or in perf
mode. For some of the components, the mode of operation doesn't matter as
they simply relay the data to the next component in the trace path. But for
sinks, they need to be able to provide the trace data back to the user.
Thus we need to make sure that "mode" is handled appropriately. e.g,
the sysfs mode could have multiple sources driving the trace data, while
perf mode doesn't allow sharing the sink.
The coresight_enable_sink() however doesn't really allow this check to
trigger as it skips the "enable_sink" callback if the component is
already enabled, irrespective of the mode. This could cause mixing
of data from different modes or even same mode (in perf), if the
sources are different. Also, if we fail to enable the sink while
enabling a path (where sink is the first component enabled),
we could end up in disabling the components in the "entire"
path which were not enabled in this trial, causing disruptions
in the existing trace paths.

This is only valid in bulk mode, as isochronous transfers have no

call returns an error when using isochronous endpoints, which we happily
ignore, but some UDCs complain in the kernel log. Fix this by only

It is good practice to make the setting of gpio-pinctrls explicitly in the
devicetree, and in this case even necessary.
Rockchip boards start with iomux settings set to gpio for most pins and
while the linux pinctrl driver also implicitly sets the gpio function if
a pin is requested as gpio that is not necessarily true for other drivers.
The issue in question stems from uboot, where the sdmmc_pwr pin is set
to function 1 (sdmmc-power) by the bootrom when reading the 1st-stage
loader. The regulator controlled by the pin is active-low though, so
when the dwmmc hw-block sets its enabled bit, it actually disables the
regulator. By changing the pin back to gpio we fix that behaviour.

Up until now, mlxsw tolerated firmware versions that weren't exactly
matching the required version, if the branch number matched. That
allowed the users to test various firmware versions as long as they were
on the right branch.
On the other hand, it made it impossible for mlxsw to put a hard lower
bound on a version that fixes all problems known to date. If a user had
a somewhat older FW version installed, mlxsw would start up just fine,
possibly performing non-optimally as it would use features that trigger
problematic behavior.
Therefore tweak the check to accept any FW version that is:
- on the same branch as the preferred version, and
- the same as or newer than the preferred version.

The microSD card slot in the Sapphire board is not working because of
several issues:
1.- The vmmc power supply is missing in the DTS. It is capable of 3.0V
and has a GPIO-based enable control.
2.- The vqmmc power supply can provide up to 3.3V, but it is capped in
the DTS to just 3.0V because of the vmmc capability. This results in a
conflict from the mmc driver requesting an unsupportable voltage range
from 3.3V to 3.0V (min > max) as reported in dmesg. So, extend the
range up to 3.3V. The hw should be able to stand this 0.3V tolerance.
See mmc_regulator_set_vqmmc in drivers/mmc/core/core.c.
3.- The card detect signal is non-working. There is a known conflict
with jtag, but the workaround in drivers/soc/rockchip/grf.c does not

setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80);
This is because it expands the macro into a non-functioning calling
sequence. The calling order must be:
outb(CX86_CCR2, 0x22);
inb(0x23);
From the comments:
* When using the old macros a line like
* setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
* gets expanded to:
* do {
* outb((CX86_CCR2), 0x22);
* outb((({
* outb((CX86_CCR2), 0x22);
* inb(0x23);
* }) | 0x88), 0x23);
* } while (0);
The new macros fix this problem, so use them instead.

[ Upstream commit 06983aa526 ]
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

[ Upstream commit b78ac6ecd1 ]
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.
