SoC glue layer changes for SGX on omap variants for v5.4

For a while we've had omap4 sgx glue layer defined in dts and probed
with ti-sysc driver. This allows idling the sgx module for PM, and
removes the need for custom platform glue layer code for any further
driver changes.

We first drop the unused legacy platform data for omap4 sgx. Then for
omap5, we need add the missing clkctrl clock data so we can configure
sgx. And we configure sgx for omap34xx, omap36xx and am3517.

For am335x, we still have a dependency for rstctrl reset driver changes,
so that will be added later on.

Note that this branch is based on earlier ti-sysc branch for omap36xx
glue layer quirk handling.

Drop legacy platform data omap variants for v5.4

We can now drop more platform data in favor of dts data for most
devices like cpsw, gpio, i2c, mmc, uart and watchdog.

In general we can do this by dropping legacy "ti,hwmods" custom dts
property, and the platform data assuming the related dts data is correct.
This is best done as single patch as otherwise we'd have to revert two
patches in case of any unexpected issues, and we're just removing data.

Fro cpsw, before we can do this, we need to configure the cpsw mdio clocks
properly in dts though in the first patch. For omap4 i2c, we've already
dropped the platform data earlier, but have been still allocting it
dynamically based on the dts data based on the "ti,hwmods" property, but
that is no longer needed. For d2d, we are missing the dts data, so we
first add it and then drop the platform data.

For dra7, we drop platform data and "ti,hwmods" for mcasp and mcspi.
We've already dropped platform data earlier for gpio, i2c, mmc, and
uart so we just need to drop "ti,hwmods" property for those.

Note that this branch is based on earlier ti-sysc-fixes branch.

Pull x86 fixes from Thomas Gleixner:
 "A set of fixes for x86:

   - Fix the bogus detection of 32bit user mode for uretprobes which
     caused corruption of the user return address resulting in
     application crashes. In the uprobes handler in_ia32_syscall() is
     obviously always returning false on a 64bit kernel. Use
     user_64bit_mode() instead which works correctly.

   - Prevent large page splitting when ftrace flips RW/RO on the kernel
     text which caused iTLB performance issues. Ftrace wants to be
     converted to text_poke() which avoids the problem, but for now
     allow large page preservation in the static protections check when
     the change request spawns a full large page.

   - Prevent arch_dynirq_lower_bound() from returning 0 when the IOAPIC
     is configured via device tree. In the device tree case the GSI 1:1
     mapping is meaningless therefore the lower bound which protects the
     GSI range on ACPI machines is irrelevant. Return the lower bound
     which the core hands to the function instead of blindly returning 0
     which causes the core to allocate the invalid virtual interupt
     number 0 which in turn prevents all drivers from allocating and
     requesting an interrupt.

   - Remove the bogus initialization of LDR and DFR in the 32bit bigsmp
     APIC driver. That uses physical destination mode where LDR/DFR are
     ignored, but the initialization and the missing clear of LDR caused
     the APIC to be left in a inconsistent state on kexec/reboot.

   - Clear LDR when clearing the APIC registers so the APIC is in a well
     defined state.

   - Initialize variables proper in the find_trampoline_placement()
     code.

On embedded environments with hard memory limits it is a normal although
rare case when skb can't be allocated on rx part under high traffic.

In such OOM cases napi_complete_done() was not called.
So the napi object became in an invalid state like it is "scheduled".
Kernel do not re-schedules the poll of that napi object.

Consequently, kernel can not remove that object the system hangs on
`ifconfig down` waiting for a poll.

We are fixing this by gracefully closing napi poll routine with correct
invocation of napi_complete_done.

This was reproduced with artificially failing the allocation of skb to
simulate an "out of memory" error case and check that traffic does
not get stuck.

Declaring threaded irq handler should also indicate the irq is
oneshot. It is oneshot indeed, because HW implements irq automasking
on trigger.

Not declaring this causes some kernel configurations to fail
on interface up, because request_threaded_irq returned an err code.

The issue was originally hidden on normal x86_64 configuration with
latest kernel, because depending on interrupt controller, irq driver
added ONESHOT flag on its own.

Issue was observed on older kernels (4.14) where no such logic exists.

qdisc, while trying to apply it:

- On an interface which is not multi-queue
- On an interface which has no carrier

The tc-cbs was also visually found to suffer of the same issue as
tc-taprio, and the fix was only compile-tested in that case.

The discussion to be made is absolutely the same as in the case of
previous patch ("taprio: Set default link speed to 10 Mbps in
taprio_set_picos_per_byte"). Nothing is lost when setting a default.

The taprio budget needs to be adapted at runtime according to interface
link speed. But that handling is problematic.

For one thing, installing a qdisc on an interface that doesn't have
carrier is not illegal. But taprio prints the following stack trace:

This happens because the qdisc ->dequeue callback gets called. Which
again is not illegal, the qdisc will dequeue even when the interface is
up but doesn't have carrier (and hence SPEED_UNKNOWN), and the frames
will be dropped further down the stack in dev_direct_xmit().

And, at the end of the day, for what? For calculating the initial budget
of an interface which is non-operational at the moment and where frames
will get dropped anyway.

So if we can't figure out the link speed, default to SPEED_10 and move
along. We can also remove the runtime check now.

taprio_init may fail earlier than this line:

	list_add(&q->taprio_list, &taprio_list);

i.e. due to the net device not being multi queue.

Attempting to remove q from the global taprio_list when it is not part
of it will result in a kernel panic.

Fix it by matching list_add and list_del better to one another in the
order of operations. This way we can keep the deletion unconditional
and with lower complexity - O(1).

In some case C1% will be wrong value, when platform doesn't have MSR for
C1 residency.

For example:
Core    CPU     CPU%c1
-       -       100.00
0       0       100.00
0       2       100.00
1       1       100.00
1       3       100.00

But adding Busy% will fix this
Core    CPU     Busy%   CPU%c1
-       -       99.77   0.23
0       0       99.77   0.23
0       2       99.77   0.23
1       1       99.77   0.23
1       3       99.77   0.23

This issue can be reproduced on most of the recent systems including
Broadwell, Skylake and later.

This is because if we don't select Busy% or Avg_MHz or Bzy_MHz then
mperf value will not be read from MSR, so it will be 0. But this
is required for C1% calculation when MSR for C1 residency is not present.
Same is true for C3, C6 and C7 column selection.

So add another define DO_BIC_READ(), which doesn't depend on user
column selection and use for mperf, C3, C6 and C7 related counters.
So when there is no platform support for C1 residency counters,
we still read these counters, if the CPU has support and user selected
display of CPU%c1.

Turbostat works by taking a snapshot of counters, sleeping, taking another
snapshot, calculating deltas, and printing out the table.

The sleep time is controlled via -i option or by user sending a signal or a
character to stdin. In the latter case, turbostat always adds 1 ms
sleep before it reads the counters, in order to avoid larger imprecisions
in the results in prints.

While the 1 ms delay may be a good idea for a "dumb" user, it is a
problem for an "aware" user. I do thousands and thousands of measurements
over a short period of time (like 2ms), and turbostat unconditionally adds
a 1ms to my interval, so I cannot get what I really need.

This patch removes the unconditional 1ms sleep. This is an expert user
tool, after all, and non-experts will unlikely ever use it in the non-fixed
interval mode anyway, so I think it is OK to remove the 1ms delay.

Commit '47936f94 tools/power turbostat: fix printing on input' make
a valid fix, but it completely disabled piped stdin support, which is
a valuable use-case. Indeed, if stdin is a pipe, turbostat won't read
anything from it, so it becomes impossible to get turbostat output at
user-defined moments, instead of the regular intervals.

There is no reason why this should works for terminals, but not for
pipes. This patch improves the situation. Instead of ignoring pipes, we
read data from them but gracefully handle the EOF case.
