[ Upstream commit 79978bff2e4b8e05ebdf5fc3ee6b794002393484 ]
We identified that the PHYs actually do not work since commit 7da7b84fee58
("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as
a coincidence of several circumstances.
The reset signal is kept asserted by a pull-down resistor on the board
unless it is deasserted by GPIO from the SoC. This is to keep the switch
dead until it is configured properly by the kernel and user space.
Prior to the referenced commit the switch was reset by the FEC driver
and the reset GPIO was actively deasserted. The mdio-bus was scanned
and the attached switch and its PHYs were found and configured.
With the referenced commit the switch is reset by the qca8k driver.
Because of another bug in the qca8k driver, functionality of the reset
pin depends on its pre-kernel configuration. See commit c44fc98f0a8f
("net: dsa: qca8k: fix illegal usage of GPIO")
The problem did not appear until we removed support for the switch
and configuration of its reset pin from the bootloader.
To fix that, properly describe the internal mdio-bus configuration of
the qca8334 switch. The PHYs are internal to the switch and sit on its
internal mdio-bus.

When the development chip ROM was added, the "direct-mapped" compatible
value was already obsolete. In addition, the device node lacked the
accompanying "probe-type" property, causing the old physmap_of_core
driver to fall back to trying all available probe types.
Unfortunately this fallback was lost when the DT and pdata cases were
merged.
Fix this by using the modern "mtd-rom" compatible value instead.

commit 68fb3ca0e408e00db1c3f8fccdfa19e274c033be upstream.
We've had issues with gcc and 'asm goto' before, and we created a
'asm_volatile_goto()' macro for that in the past: see commits
3f0116c3238a ("compiler/gcc4: Add quirk for 'asm goto' miscompilation
bug") and a9f180345f53 ("compiler/gcc4: Make quirk for
asm_volatile_goto() unconditional").
Then, much later, we ended up removing the workaround in commit
43c249ea0b1e ("compiler-gcc.h: remove ancient workaround for gcc PR
58670") because we no longer supported building the kernel with the
affected gcc versions, but we left the macro uses around.
Now, Sean Christopherson reports a new version of a very similar
problem, which is fixed by re-applying that ancient workaround. But the
problem in question is limited to only the 'asm goto with outputs'
cases, so instead of re-introducing the old workaround as-is, let's
rename and limit the workaround to just that much less common case.
It looks like there are at least two separate issues that all hit in
this area:
(a) some versions of gcc don't mark the asm goto as 'volatile' when it
has outputs:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420
which is easy to work around by just adding the 'volatile' by hand.
(b) Internal compiler errors:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422
which are worked around by adding the extra empty 'asm' as a
barrier, as in the original workaround.
but the problem Sean sees may be a third thing since it involves bad
code generation (not an ICE) even with the manually added 'volatile'.
The same old workaround works for this case, even if this feels a
bit like voodoo programming and may only be hiding the issue.

The DP/DM wakeup interrupts are edge triggered and which edge to trigger
on depends on use-case and whether a Low speed or Full/High speed device
is connected.

The binding erroneously decreed that the SCMI variants of the ST
evaluation kits are compatible with the non-SCMI variants.
This is not correct, as a kernel or bootloader compatible with the non-SCMI
variant is not necessarily able to function, when direct access
to resources is replaced by having to talk SCMI to the secure monitor.
The binding has been adjusted to reflect thus, so synchronize the device
trees now.

With subtle timings changes, we can now sometimes get an external abort on
non-linefetch error booting am3 devices at sysc_reset(). This is because
of a missing reset delay needed for the usb target module.
Looks like we never enabled the delay earlier for am3, although a similar
issue was seen earlier with a similar usb setup for dm814x as described in

There are several functions involved for performing the functionality
of evtchn_do_upcall():
- __xen_evtchn_do_upcall() doing the real work
- xen_hvm_evtchn_do_upcall() just being a wrapper for
__xen_evtchn_do_upcall(), exposed for external callers
- xen_evtchn_do_upcall() calling __xen_evtchn_do_upcall(), too, but
without any user
Simplify this maze by:
- removing the unused xen_evtchn_do_upcall()
- removing xen_hvm_evtchn_do_upcall() as the only left caller of
__xen_evtchn_do_upcall(), while renaming __xen_evtchn_do_upcall() to
xen_evtchn_do_upcall()

Place IRQ handlers such as gic_handle_irq() in the irqentry section even
if FUNCTION_GRAPH_TRACER is not enabled. Without this, the stack
depot's filter_irq_stacks() does not correctly filter out IRQ stacks in
those configurations, which hampers deduplication and eventually leads
to "Stack depot reached limit capacity" splats with KASAN.

[ Upstream commit c0e824661f443b8cab3897006c1bbc69fd0e7bc4 ]
memset() description in ISO/IEC 9899:1999 (and elsewhere) says:
The memset function copies the value of c (converted to an
unsigned char) into each of the first n characters of the
object pointed to by s.
The kernel's arm32 memset does not cast c to unsigned char. This results
in the following code to produce erroneous output:
char a[128];
memset(a, -128, sizeof(a));
This is because gcc will generally emit the following code before
it calls memset() :
mov r0, r7
mvn r1, #127 ; 0x7f
bl 00000000 <memset>
r1 ends up with 0xffffff80 before being used by memset() and the
'a' array will have -128 once in every four bytes while the other
bytes will be set incorrectly to -1 like this (printing the first
8 bytes) :
test_module: -128 -1 -1 -1
test_module: -1 -1 -1 -128
The change here is to 'and' r1 with 255 before it is used.
