This patch backs out a change that came in during the merge window which
selects a configuration for GPIO4 on pcm512x CODECs that may not be
suitable for all systems using the device. Changes for v4.1 will make
this properly configurable but for now it's safest to revert to the
v3.19 behaviour and leave the pin configuration alone.
Sorry for sending this direct at the last minute but due to the GPIO
misuse it'd be really good to get it in the release and I'd not realised
it hadn't been sent yet - between some travel, a job change and other
non-urgent fixes coming in I'd lost track of the urgency. It's been in
-next for several weeks now, is isolated to the driver and fairly clear
to inspection.

ASoC: pcm512x: Remove hardcoding of pll-lock to GPIO4
Currently GPIO4 is hardcoded to output the pll-lock signal.
Unfortunately this is after the pll-out GPIO is configured which
is selectable in the device tree. Therefore it is not possible to
use GPIO4 for pll-out. Therefore this patch removes the
configuration of GPIO4.

This reverts commit ecc19d17868be9c9f8f00ed928791533c420f3e0.
It added a new warning to try to encourage driver writers to set the
device capabities properly, but drivers haven't been updated and in the
meantime it just generaters a scary message that users cannot actually
do anything about.
Warnings like these are appropriate if you actually expect to fix the
code that causes them. They are not appropriate for releases.

Jan Engelhardt reports a strange oops with an invalid ->sense_buffer
pointer in scsi_init_cmd_errh() with the blk-mq code.
The sense_buffer pointer should have been initialized by the call to
scsi_init_request() from blk_mq_init_rq_map(), but there seems to be
some non-repeatable memory corruptor.
This patch makes sure we initialize the whole struct request allocation
(and the associated 'struct scsi_cmnd' for the SCSI case) to zero, by
using __GFP_ZERO in the allocation. The old code initialized a couple
of individual fields, leaving the rest undefined (although many of them
are then initialized in later phases, like blk_mq_rq_ctx_init() etc.
It's not entirely clear why this matters, but it's the rigth thing to do
regardless, and with 4.0 imminent this is the defensive "let's just make
sure everything is initialized properly" patch.

In cases of short transfer times the CPU is spending lots of time
in the interrupt handler and scheduler to reschedule the worker thread.
Measurements show that we have times where it takes 29.32us to between
the last clock change and the time that the worker-thread is running again
returning from wait_for_completion_timeout().
During this time the interrupt-handler is running calling complete()
and then also the scheduler is rescheduling the worker thread.
This time can vary depending on how much of the code is still in
CPU-caches, when there is a burst of spi transfers the subsequent delays
are in the order of 25us, so the value of 30us seems reasonable.
With polling the whole transfer of 4 bytes at 10MHz finishes after 6.16us
(CS down to up) with the real transfer (clock running) taking 3.56us.
So the efficiency has much improved and is also freeing CPU cycles,
reducing interrupts and context switches.
Because of the above 30us seems to be a reasonable limit for polling.

Transforms the bcm-2835 native SPI-chip select to their gpio-cs equivalent.
This allows for some support of some optimizations that are not
possible due to HW-gliches on the CS line - especially filling
the FIFO before enabling SPI interrupts (by writing to CS register)
while the transfer is already in progress (See commit: e3a2be3030e2)
This patch also works arround some issues in bcm2835-pinctrl which does not
set the value when setting the GPIO as output - it just sets up output and
(typically) leaves the GPIO as low. When a fix for this is merged then this
gpio_set_value can get removed from bcm2835_spi_setup.

On modern systems the regulator hierarchy can get quite long and nested
with regulators supplying other regulators. In some cases when debugging
it might be nice to get a tree of these regulators, their consumers
and the regulation constraints in one go.
To achieve this add a regulator_summary sysfs node, similar to
clk_summary in the common clock framework, that walks the regulator
list and creates a tree out of the regulators, their consumers and
core per-regulator settings.
On a rk3288-firefly the regulator_summary would for example look
something like:
