Not all devices on an MDIO bus are PHYs. Meaning not all MDIO drivers
are PHY drivers. Add support for generic MDIO drivers.

The control cpu thread which initiates hotplug calls kthread_park()
for hotplug thread and sets KTHREAD_SHOULD_PARK. After this control
thread wakes up the hotplug thread. There is a chance that wakeup
code sees the hotplug thread (running on AP core) in INTERRUPTIBLE
state, but sets its state to RUNNING after hotplug thread has entered
kthread_parkme() and changed its state to TASK_PARKED. This can result
in panic later on in kthread_unpark(), as it sees KTHREAD_IS_PARKED
flag set but fails to rebind the kthread, due to it being not in
TASK_PARKED state. Fix this, by serializing wakeup state change,
against state change before parking the kthread.
Below is the possible race:
Control thread Hotplug Thread
kthread_park()
set KTHREAD_SHOULD_PARK
smpboot_thread_fn
set_current_state(TASK_INTERRUPTIBLE);
kthread_parkme
wake_up_process()
raw_spin_lock_irqsave(&p->pi_lock, flags);
if (!(p->state & state)) -> this will fail
goto out;
__kthread_parkme
__set_current_state(TASK_PARKED);
if (p->on_rq && ttwu_remote(p, wake_flags))
ttwu_remote()
p->state = TASK_RUNNING;
schedule();
So to avoid this race, take pi_lock to serial state changes.

During composition switch, current driver ends up calling
rndis_ipa_cleanup twice without calling rndis_ipa_init() in between.
This could cause spinbug in IPA driver due to uninitialized spin lock.
Hence fix the issue by moving rndis_ipa_init() to bind() callback and
calling rndis_ipa_cleanup() in unbind() callback.

This size is the maximum amount of virtual address space we gather
up before attempting to purge with a TLB flush. It is 128M in most cases.
With repeated and high size vmalloc operations, it may easily generate
more fragments. This is wasting limited vmalloc area, for 32bits.
So make it configable and the default multiplier as 8, 32bits only.

The thread which initiates the hot plug can get scheduled
out, while trying to acquire the console lock,
thus increasing the hot plug latency. This option
allows to selectively disable the console flush and
in turn reduce the hot plug latency.

scm_call2() API can block indefinitely if another client is using
this API. This is due to a mutex in this API to serialize calls to
the TZ. This blocks the GPU wake up which in turn can result in
kgsl fence timeouts. Since CPZ register programing is handled at
the hypervisor, we can safely avoid this serialization by using
scm_call2_atomic() API which doesn't block.
