With the current implementation of GPIO hogging and with
gpio-pcf857x is built as module, ethernet doesn't work on boot
and doesn't throw any error/warning to user. Ethernet becomes
operational when inserting gpio-pcf857x module, even this time
there is no error/warning logs to user that ethernet is
operational.
When using with NFS rootfs and gpio-pcf857x as module, board
doesn't boot as it doesn't get any ip address and doesn't throw
any error/warning. To over come this, now cpsw driver tries to
get mode-gpios. When gpio-pcf857x is built as module it will
throw error, so that user can decide either to built in

re-probes again when gpio-pcf857x module is inserted and ethernet

We currently do a single update of the vgic state when the distributor
enable/disable control register is accessed and then bypass updating the
state for as long as the distributor remains disabled.
This is incorrect, because updating the state does not consider the
distributor enable bit, and this you can end up in a situation where an
interrupt is marked as pending on the CPU interface, but not pending on
the distributor, which is an impossible state to be in, and triggers a
warning. Consider for example the following sequence of events:
1. An interrupt is marked as pending on the distributor
- the interrupt is also forwarded to the CPU interface
2. The guest turns off the distributor (it's about to do a reboot)
- we stop updating the CPU interface state from now on
3. The guest disables the pending interrupt
- we remove the pending state from the distributor, but don't touch
the CPU interface, see point 2.
Since the distributor disable bit really means that no interrupts should
be forwarded to the CPU interface, we modify the code to keep updating
the internal VGIC state, but always set the CPU interface pending bits
to zero when the distributor is disabled.

When a guest reboots or offlines/onlines CPUs, it is not uncommon for it
to clear the pending and active states of an interrupt through the
emulated VGIC distributor. However, since the architected timers are
defined by the architecture to be level triggered and the guest
rightfully expects them to be that, but we emulate them as
edge-triggered, we have to mimic level-triggered behavior for an
edge-triggered virtual implementation.
We currently do not signal the VGIC when the map->active field is true,
because it indicates that the guest has already been signalled of the
interrupt as required. Normally this field is set to false when the
guest deactivates the virtual interrupt through the sync path.
We also need to catch the case where the guest deactivates the interrupt
through the emulated distributor, again allowing guests to boot even if
the original virtual timer signal hit before the guest's GIC
initialization sequence is run.

We have an interesting issue when the guest disables the timer interrupt
on the VGIC, which happens when turning VCPUs off using PSCI, for
example.
The problem is that because the guest disables the virtual interrupt at
the VGIC level, we never inject interrupts to the guest and therefore
never mark the interrupt as active on the physical distributor. The
host also never takes the timer interrupt (we only use the timer device
to trigger a guest exit and everything else is done in software), so the
interrupt does not become active through normal means.
The result is that we keep entering the guest with a programmed timer
that will always fire as soon as we context switch the hardware timer
state and run the guest, preventing forward progress for the VCPU.
Since the active state on the physical distributor is really part of the
timer logic, it is the job of our virtual arch timer driver to manage
this state.
The timer->map->active boolean field indicates whether we have signalled
this interrupt to the vgic and if that interrupt is still pending or
active. As long as that is the case, the hardware doesn't have to
generate physical interrupts and therefore we mark the interrupt as
active on the physical distributor.
We also have to restore the pending state of an interrupt that was
queued to an LR but was retired from the LR for some reason, while
remaining pending in the LR.

This flag is implied by the GIC driver, and indeed the VGIC code only
makes sense if a GIC is present. This changes the CONFIG_KVM symbol
to always select GIC, which avoids the issue.

The i2c-au1550 driver has to program various setup and hold times
for the sda/scl signals by hand. The current values seem to be
working best when the driver is supplied with 50MHz, however on the
DB1300 board 48MHz is the closest we can get to it, and the timings
are a bit too tight for that, leading to the last bit of a transmission
sometimes being swallowed. This manifests itself in wrong readings
of the ne1619 sensor and inability to configure the wm8731 i2s codec.
With the relaxed timings, both the sensor and the i2s codec can now
be accessed more reliably over a wider range of I2C block input
frequencies.

The stack tracer was triggering the WARN_ON() in module.c:
static void module_assert_mutex_or_preempt(void)
{
#ifdef CONFIG_LOCKDEP
if (unlikely(!debug_locks))
return;
WARN_ON(!rcu_read_lock_sched_held() &&
!lockdep_is_held(&module_mutex));
#endif
}
The reason is that the stack tracer traces all function calls, and some of
those calls happen while exiting or entering user space and idle. Some of
these functions are called after RCU had already stopped watching, as RCU
does not watch userspace or idle CPUs.
If a max stack is hit, then the save_stack_trace() is called, which will
check module addresses and call module_assert_mutex_or_preempt(), and then
trigger the warning. Sad part is, the warning itself will also do a stack
trace and tigger the same warning. That probably should be fixed.
The warning was added by 0be964be0d "module: Sanitize RCU usage and
locking" but this bug has probably been around longer. But it's unlikely to
cause much harm, but the new warning causes the system to lock up.

According to "KeyStone Architecture Inter-IC Control Bus User Guide", fixed
additive part of frequency divisors (referred as "d" in the code and datasheet)
always equals to 6, independent of module clock prescaler.
module clock frequency
master clock frequency = ----------------------
(ICCL + 6) + (ICCH + 6)
It was not the case with original Davinci IP. Introduce new compatible property
"ti,keystone-i2c", which triggers special handling in the driver.
Without this change Keystone-based systems (having 204.8MHz input clock) choose
prescaler 29 (PSC=28). Using d=5 in this case leads to bus bitrate ~353kHz
instead of requested 400kHz. After correction, assuming d=6 bus rate is ~392kHz.
This gives ~11% transfer rate increase.

After suspend to RAM the device stopped to work with ETIMEDOUT error:
$ dd if=/dev/hwrng of=/dev/null bs=1 count=16
dd: reading `/dev/hwrng': Connection timed out
In the STATUS register the bits #5 (PRNG_DONE) and #1
(SEED_SETTING_DONE) were not set. Instead PRNG_ERROR (seventh bit) was
high.
After each system suspend initialize the seed to fix the error.

Driver may hang waiting indefinitely for PRNG to finish its
