Add DT bindings for Broadcom STB USB EHCI and XHCI drivers.
NOTE: The OHCI driver is not included because it uses the generic
platform driver.

This patch adds USB role switch support to the tps6598x.
The setup to initiate or accept a data-role switch is both assumed and
currently required to be baked-into the firmware as described in TI's
document here.
Link: https://www.ti.com/lit/an/slva843a/slva843a.pdf
With this change its possible to use the USB role-switch API to detect and
notify role-switches to downstream consumers.
Tested with a ChipIdea controller on a Qualcomm MSM8939.

The SBU and HSL orientation may be fixed/static from the mux
PoW. Apparently the retimer may take care of the orientation
of these lines. Handling the static SBU (AUX) and HSL
orientation with device properties.
If the SBU orientation is static, a device property
"sbu-orintation" can be used. When the property exists, the
driver always sets the SBU orientation according to the
property value, and when it's not set, the driver uses the
cable plug orientation with SBU.
And with static HSL orientation, "hsl-orientation" device
property can be used in the same way.

Right now we don't report to user-space a role switch when doing a
usb_role_switch_set_role() despite having registered the uevent callbacks.
This patch switches on the notifications allowing user-space to see
role-switch change notifications and subsequently determine the current
controller data-role.

scsi_get_host_dev() will create a virtual device such that either
the target id is ignored from scanning (if 'this_id' is set to
something which can be reached during scanning) or if the driver
needs a scsi device for the HBA to send commands to.
Neither is true for sierra-ms; 'this_id' remains at the default
value '-1' and the created device is never ever used within
the driver.
So kill it.

The implementation of show_stack will panic with wrong fp:
addr = *fp++;
because the fp isn't checked properly.
The current implementations of show_stack, wchan and stack_trace
haven't been designed properly, so just deprecate them.
This patch is a reference to riscv's way, all codes are modified from
arm's. The patch is passed with:
- cat /proc/<pid>/stack
- cat /proc/<pid>/wchan
- echo c > /proc/sysrq-trigger

Addition of the new internal API to get the clkctrl names missed adding
the same conversion in place for the subclocks. This leads into missed
parent/child relationships (i.e. orphaned clocks) with mixed node name
handling, for example with omap4/omap5 where the l4_per clocks are using
new naming, but rest are using old. Fix by converting the subclock
registration to pick correct names for the clocks also.

Right now, trying to use RTC purely with the ti-sysc / clkctrl framework
fails to enable the RTC module properly. Based on experimentation, this
appears to be because RTC is sourced from the clkdiv32k optional clock.

The cipso and calipso code can set the MLS_CAT attribute on
successful parsing, even if the corresponding catmap has
not been allocated, as per current configuration and external
input.
Later, selinux code tries to access the catmap if the MLS_CAT flag
is present via netlbl_catmap_getlong(). That may cause null ptr
dereference while processing incoming network traffic.
Address the issue setting the MLS_CAT flag only if the catmap is
really allocated. Additionally let netlbl_catmap_getlong() cope
with NULL catmap.

pll_a_out0 and the I2S clocks are already configured to default to rates
corresponding to a 44.1 kHz sampling rate, but the pll_a configuration
was set to a default that is not listed in the frequency table, which
caused the PLL code to compute an invalid configuration. As a result of
this invalid configuration, Jetson TK1 fails to resume from suspend.
This used to get papered over because the ASoC driver would force audio
clocks to a 44.1 kHz configuration on boot. However, that's not really
necessary and was hence removed in commit ff5d18cb04f4 ("ASoC: tegra:
Enable audio mclk during tegra_asoc_utils_init()").
Fix the initial rate for pll_a so that it matches the 44.1 kHz entry in
the pll_a frequency table.

I was able to trigger it on other machines, when I added to the kernel
command line of both "ftrace=function" and "trace_options=func_stack_trace".
The cause is the "ftrace=function" would register the function tracer
and create a trampoline, and it will set it as executable and
read-only. Then the "trace_options=func_stack_trace" would then update
the same trampoline to include the stack tracer version of the function
tracer. But since the trampoline already exists, it updates it with
text_poke_bp(). The problem is that text_poke_bp() called while
system_state == SYSTEM_BOOTING, it will simply do a memcpy() and not
the page mapping, as it would think that the text is still read-write.
But in this case it is not, and we take a fault and crash.
Instead, lets keep the ftrace trampolines read-write during boot up,
and then when the kernel executable text is set to read-only, the
ftrace trampolines get set to read-only as well.

When multiple async FDs were allowed to exist the idea was for all
broadcast events to be delivered to all async FDs, however
IB_EVENT_DEVICE_FATAL was missed.
Instead of having ib_uverbs_free_hw_resources() special case the global
async_fd, have it cause the event during the uobject destruction. Every
async fd is now a uobject so simply generate the IB_EVENT_DEVICE_FATAL
while destroying the async fd uobject. This ensures every async FD gets a
copy of the event.

The commit below moved all of the destruction to the disassociate step and
cleaned up the event channel during destroy_uobj.
However, when ib_uverbs_free_hw_resources() pushes IB_EVENT_DEVICE_FATAL
and then immediately goes to destroy all uobjects this causes
ib_uverbs_free_event_queue() to discard the queued event if userspace
hasn't already read() it.
Unlike all other event queues async FD needs to defer the
ib_uverbs_free_event_queue() until FD release. This still unregisters the
handler from the IB device during disassociation.

We autotune rcvbuf whenever SO_RCVLOWAT is set to account for 100%
overhead in tcp_set_rcvlowat()
This works well when skb->len/skb->truesize ratio is bigger than 0.5
But if we receive packets with small MSS, we can end up in a situation
where not enough bytes are available in the receive queue to satisfy
RCVLOWAT setting.
As our sk_rcvbuf limit is hit, we send zero windows in ACK packets,
preventing remote peer from sending more data.
Even autotuning does not help, because it only triggers at the time
user process drains the queue. If no EPOLLIN is generated, this
can not happen.
Note poll() has a similar issue, after commit
c7004482e8dc ("tcp: Respect SO_RCVLOWAT in tcp_poll().")

My recent commit b6d49cab44b5 ("net: Make PTP-specific drivers depend on
PTP_1588_CLOCK") exposes a missing dependency in defconfigs that select
TI_CPTS without selecting PTP_1588_CLOCK, leading to linker errors of the
form:
drivers/net/ethernet/ti/cpsw.o: in function `cpsw_ndo_stop':
cpsw.c:(.text+0x680): undefined reference to `cpts_unregister'
...
That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ of
cpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in these
configurations, but TI_CPTS (which is the symbol gating _calls_ to the cpts
functions) _is_ enabled. So we end up compiling calls to functions that
don't exist, resulting in the linker errors.
This patch fixes build errors and restores previous behavior by:
- ensure PTP_1588_CLOCK=y in TI specific configs and CPTS will be built
- remove TI_CPTS_MOD and, instead, add dependencies from CPTS in
TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV as below:
config TI_CPSW_SWITCHDEV
...
depends on TI_CPTS || !TI_CPTS
which will ensure proper dependencies PTP_1588_CLOCK -> TI_CPTS ->
TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV and build type selection.
Note. For NFS boot + CPTS all of above configs have to be built-in.

Since the fw has been re-inited, we need to refresh the port

Let's call ionic_port_init again, and tweak it to allow for
a call to simply refresh the existing dma address.

When running in a bond setup, or some other potential
configurations, the netdev mac may have been changed from
the default device mac. Since the userland doesn't know
about the changes going on under the covers in a fw-upgrade
it doesn't know the re-push the mac filter. The driver
needs to leave the netdev mac filter alone when rebuilding
after the fw-upgrade.

When the other MPTCP-peer uses 32-bit data-sequence numbers, we rely on
map_seq to indicate how to expand to a 64-bit data-sequence number in
expand_seq() when receiving data.
For new subflows, this field is not initialized, thus results in an
"invalid" mapping being discarded.
Fix this by initializing map_seq upon subflow establishment time.

Unfortunately, the last set of fixes introduced some minor bugs:

zero.
- The preempt_irq_delay_thread fix to make the creation code wait for
the kthread to finish to prevent it from executing after module
unload, can now cause the kthread to exit before it even executes
(preventing it to run its tests).
- The fix to the bootconfig that fixed the initrd to remove the
bootconfig from causing the kernel to panic, now prints a warning
that the bootconfig is not found, even when bootconfig is not on
the command line"

Control dependencies do not guarantee load order across the condition,
allowing a CPU to predict and speculate memory reads.
Commit 324b494c2862 inlined verifying a new completion with its
handling. At least one architecture was observed to access the contents
out of order, resulting in the driver using stale data for the
completion.
Add a dma read barrier before reading the completion queue entry and
after the condition its contents depend on to ensure the read order is
determinsitic.
