The DDC error IRQs will fire on the IT6610 every time the FIFO is empty,
which is not very helpful. To resolve this, we can simply disable them,
and handle DDC errors in it66121_wait_ddc_ready().

Power reset maybe generate unexpected signal. In order to avoid
the glitch issue, we need to enable isolation first to guarantee the
stable signal when power reset is triggered.

The function it66121_wait_ddc_ready() would previously read the status
register until "true", which means it never actually polled anything and
would just read the register once.
Now, it will properly wait until the DDC hardware is ready or until it
reported an error.
The 'busy' variable was also renamed to 'error' since these bits are set
on error and not when the DDC hardware is busy.
Since the DDC ready function is now working properly, the msleep(20) can
be removed.

Russell King correctly pointed out that the MAC_2500FD capability is
already added for port 5 (if not in RGMII mode) and port 6 (which only
supports SGMII) by mt7531_mac_port_get_caps. Remove the reduntant
setting of this capability flag which was added by a previous commit.

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.

The default setting of end_time minus start_time is whole 1 second.
Thus, if it's not being configured in any GCL entry then it will be
staying at original 1 second.
This patch is changing the start_time and end_time to be end_time as
if setting zero will be having weird HW behavior where the gate will
not be fully closed.

Qbv users can specify a cycle time that is not equal to the total GCL
intervals. Hence, recalculation is necessary here to exclude the time
interval that exceeds the cycle time. As those GCL which exceeds the
cycle time will be truncated.
According to IEEE Std. 802.1Q-2018 section 8.6.9.2, once the end of
the list is reached, it will switch to the END_OF_CYCLE state and
leave the gates in the same state until the next cycle is started.

The I225 hardware has a limitation that packets can only be scheduled
in the [0, cycle-time] interval. So, scheduling a packet to the start
of the next cycle doesn't usually work.
To overcome this, we use the Transmit Descriptor first flag to indicates
that a packet should be the first packet (from a queue) in a cycle
according to the section 7.5.2.9.3.4 The First Packet on Each QBV Cycle
in Intel Discrete I225/6 User Manual.
But this only works if there was any packet from that queue during the
current cycle, to avoid this issue, we issue an empty packet if that's
not the case. Also require one more descriptor to be available, to take
into account the empty packet that might be issued.
Test Setup:
Talker: Use l2_tai to generate the launchtime into packet load.
Listener: Use timedump.c to compute the delta between packet arrival
and LaunchTime packet payload.
Test Result:

Pull kvm updates from Paolo Bonzini:
"ARM64:
- Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.
- Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.
- Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
option, which multi-process VMMs such as crosvm rely on (see merge
commit 382b5b87a97d: "Fix a number of issues with MTE, such as
races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").
- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.
- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.
- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.
- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.
s390:
- Second batch of the lazy destroy patches
- First batch of KVM changes for kernel virtual != physical address
support
- Removal of a unused function
x86:
- Allow compiling out SMM support
- Cleanup and documentation of SMM state save area format
- Preserve interrupt shadow in SMM state save area
- Respond to generic signals during slow page faults
- Fixes and optimizations for the non-executable huge page errata
fix.
- Reprogram all performance counters on PMU filter change
- Cleanups to Hyper-V emulation and tests
- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)
- Advertise several new Intel features
- x86 Xen-for-KVM:
- Allow the Xen runstate information to cross a page boundary
- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
- Add support for 32-bit guests in SCHEDOP_poll
- Notable x86 fixes and cleanups:
- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.
- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.
- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.
- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.
- Advertise (on AMD) that the SMM_CTL MSR is not supported
- Remove unnecessary exports
Generic:
- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
Selftests:
- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.
- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.
- Introduce actual atomics for clear/set_bit() in selftests
- Add support for pinning vCPUs in dirty_log_perf_test.
- Rename the so called "perf_util" framework to "memstress".
- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.
- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.
- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).
- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.
- x86-specific selftest changes:
- Clean up x86's page table management.
- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.
- Clean up the nEPT support checks.
- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
before the test opts in via prctl().
Documentation:
- Remove deleted ioctls from documentation
- Clean up the docs for the x86 MSR filter.

the guidance is to only program it in the specific steppings associated

The API is not in use. And it's unlikely to be used in
the future either.

One-element arrays are deprecated, and we are replacing them with
flexible array members instead. So, replace one-element array with
flexible-array member in structs _ATOM_DISPLAY_OBJECT_PATH,
_ATOM_DISPLAY_OBJECT_PATH_TABLE, _ATOM_OBJECT_TABLE, GOP_VBIOS_CONTENT
_ATOM_GPIO_VOLTAGE_OBJECT_V3 and refactor the rest of the code accordingly.
It's worth mentioning that doing a build before/after this patch
results in no binary output differences.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].
