Anatop is an integrated regulator inside i.MX6 SoC.
There are 3 digital regulators which controls PU, CORE (ARM), and SOC.
And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB).
This patch adds the Anatop regulator driver.

The current implementation does not always flush the threaded handler
when disabling the irq. In case the irq handler was called, but the
threaded handler hasn't started running yet, the interrupt will be
flagged as pending, and the handler will not run. This implementation
has some issues:
First, if the interrupt is a wake source and flagged as pending, the
system will not be able to suspend.
Second, when quickly disabling and re-enabling the irq, the threaded
handler might continue to run after the irq is re-enabled without the
irq handler being called first. This might be an unexpected behavior.
In addition, it might be counter-intuitive that the threaded handler
will not be called even though the irq handler was called and returned
IRQ_WAKE_THREAD.
Fix this by always waiting for the threaded handler to complete in
synchronize_irq().

When padata_do_parallel() is called from multiple cpus for the same
padata instance, we can get object reordering on sequence number wrap
because testing for sequence number wrap and reseting the sequence
number must happen atomically but is implemented with two atomic
operations. This patch fixes this by converting the sequence number
from atomic_t to an unsigned int and protect the access with a
spin_lock. As a side effect, we get rid of the sequence number wrap
handling because the seqence number wraps back to null now without
the need to do anything.

This patch addresses a iscsi-target specific bug related to reservation conflict
handling in iscsit_handle_scsi_cmd() that has been causing reservation conflicts
to complete and not fail as expected due to incorrect errno checking. The problem
occured with the change to return -EBUSY from transport_generic_cmd_sequencer() ->
transport_generic_allocate_tasks() failures, that broke iscsit_handle_scsi_cmd()
checking for -EINVAL in order to invoke a non GOOD status response.
This was manifesting itself as data corruption with legacy SPC-2 reservations,
but also effects iscsi-target LUNs with SPC-3 persistent reservations.

This patch addresses a bug with target_check_scsi2_reservation_conflict()
return checking in target_scsi2_reservation_[reserve,release]() that was
preventing CRH=1 operation from silently succeeding in the two special
cases defined by SPC-3, and not failing with reservation conflict status
when dealing with legacy RESERVE/RELEASE + active SPC-3 PR logic.
Also explictly set cmd->scsi_status = SAM_STAT_RESERVATION_CONFLICT during
the early non reservation holder failure from pr_ops->t10_seq_non_holder()
check in transport_generic_cmd_sequencer() for fabrics that already expect
it to be set.

Since then any use of "variable length arrays" has become blasphemous.
Even in perfectly good, beautiful, perfectly safe code like the one
below where the variable length arrays are only used as a sizeof()
parameter, for type-safe dynamic structure allocations. GCC is not
executing any stack allocation code.
I have produced a small file which defines two functions main1(unsigned numdevs)
and main2(unsigned numdevs). main1 uses code as before with call to malloc
and main2 uses code as of after this patch. I compiled it as:
gcc -O2 -S see_asm.c
and here is what I get:
<see_asm.s>
main1:
.LFB7:
.cfi_startproc
mov %edi, %edi
leaq 4(%rdi,%rdi), %rdi
salq $3, %rdi
jmp malloc
.cfi_endproc
.LFE7:
.size main1, .-main1
.p2align 4,,15
.globl main2
.type main2, @function
main2:
.LFB8:
.cfi_startproc
mov %edi, %edi
addq $2, %rdi
salq $4, %rdi
jmp malloc
.cfi_endproc
.LFE8:
.size main2, .-main2
.section .text.startup,"ax",@progbits
.p2align 4,,15
</see_asm.s>
*Exact* same code !!!
So please seriously consider not accepting this patch and leave the
perfectly good code intact.

Any guest behavior that is not completely ignoring console/0 is going

Returning 0 or -ENODEV from xencons_probe is not enough because it is
