The regulators set consists of 4 BUCKs. The output
voltages are configurable and are meant to supply power to the
main processor and other components. The ramp delay is configurable
for all BUCKs. The BUCKs can be configured in single phase or
multiphase modes.

Commit 43530b69d7 ("regulator: Use
regmap_read/write(), regmap_update_bits functions directly") intended
to replace working inline helper functions with standard regmap
calls. However, it also inverted the set/clear logic of the "CORE ADJ
Allowed" bit. That patch was clearly never tested, since without that
bit cleared, the core VDCDC1 voltage output does not react to I2C
configuration changes.
This patch fixes the issue by clearing the bit as in the original,
correct implementation. Note for stable back porting that, due to
subsequent driver churn, this patch will not apply on every kernel

After commit 66d228a2bf ("regulator: core: Don't use regulators as
supplies until the parent is bound"), input supplies aren't resolved
if the input supplies parent device has not been bound. This prevent
regulators to hold an invalid reference if its supply parent device
driver probe is deferred.
But this causes issues on some boards where a PMIC's regulator use as
input supply a regulator from another PMIC whose driver is registered
after the driver for the former.
In this case the regulators for the first PMIC will fail to resolve
input supplies on regulators registration (since the other PMIC wasn't
probed yet). And when the core attempts to resolve again latter when
the other PMIC registers its own regulators, it will fail again since
the parent device isn't bound yet.
This will cause some parent supplies to never be resolved and wrongly
be disabled on boot due taking them as unused.
To solve this problem, also attempt to resolve the pending regulators
input supplies before disabling the unused regulators.

The code in _regulator_get() got a bit confusing over time, with control
flow jumping to a label from couple of places. Let's untangle it a bit by
doing the following:
1. Make handling of missing supplies and substituting them with dummy
regulators more explicit:
- check if we not have full constraints and refuse considering dummy
regulators with appropriate message;
- use "switch (get_type)" to handle different types of request explicitly
as well. "Normal" requests will get dummies, exclusive will not and
will notify user about that; optional will fail silently.
2. Stop jumping to a label in the middle of the function but instead have
proper conditional flow. I believe jumps should be reserved for error
handling, breaking from inner loop, or restarting a loop, but not for
implementing normal conditional flow.

Instead of separate "exclusive" and "allow_dummy" arguments, that formed 3
valid combinations (normal, exclusive and optional) and an invalid one,
let's accept explicit "get_type", like we did in devm-managed code.

There is no point in assigning value to 'ret' before calling
regulator_dev_lookup() as it will clobber 'ret' anyway.
Also, let's explicitly return -PROBE_DEFER when try_module_get() fails,
instead of relying that earlier initialization of "regulator" carries
correct value.

Three changes here, two run of the mill driver specific fixes and a
change from Mark Rutland which reverts some new device specific ACPI
binding code which was added during the merge window as there are
concerns about this sending the wrong signal about usage of regulators
in ACPI systems.

In some rare configurations we can run into rather high kernel stack
consumption:
drivers/regulator/s2mpa01.c:397:1: error: the frame size of 1536 bytes is larger than 1152 bytes [-Werror=frame-larger-than=]
This is probably harmless since it happens only in the probe function,
but there is also a relatively simple workaround, moving the regulator
match data into the device specific structure.
As a small downside, we waste a little memory at runtime. An alternative
approach would free the array at the end of the probe function, which in
turn is a little more complicated.

This reverts commit 13bed58ce8 (regulator: fixed: add support for ACPI
interface).
While there does appear to be a practical need to manage regulators on ACPI
systems, using ad-hoc properties to describe regulators to the kernel presents
a number of problems (especially should ACPI gain first class support for such
things), and there are ongoing discussions as to how to manage this.
Until there is a rough consensus, revert commit 13bed58ce8, which hasn't
been in a released kernel yet as discussed in [1] and the surrounding thread.

Add code to support support for "anatop-enable-bit" device-tree
property. This property translates to LINREG_ENABLE bit in real hardware
and is present on 1p1, 2p5 and 3p0 regulators on i.MX6 and 1p0d regulator
on i.MX7.

When regulators are successfully registered, we check to see if the
regulator is a supply for any other registered regulator and if so
add the new regulator as the supply for the existing regulator(s).
Some devices, such as Power Management ICs, may register a series of
regulators when probed and there are cases where one of the regulators
may fail to register and defer the probing of the parent device. In this
case any successfully registered regulators would be unregistered so
that they can be re-registered at some time later when the probe is
attempted again. However, if one of the regulators that was registered
was added as a supply to another registered regulator (that did not
belong to the same parent device), then this supply regulator was
unregister again because the parent device is probe deferred, then a
regulator could be holding an invalid reference to a supply regulator
that has been unregistered. This will lead to a system crash if that
regulator is then used.
Although it would be possible to check when unregistering a regulator
if any other regulator in the system is using it as a supply, it still
may not be possible to remove it as a supply if this other regulator is
in use. Therefore, fix this by preventing any regulator from adding
another regulator as a supply if the parent device for the supply
regulator has not been bound and if the parent device for the supply
and the regulator are different. This will allow a parent device that is
registering regulators to be probe deferred and ensure that none of the
regulators it has registered are used as supplies for any other
regulator from another device.

The name of a codec pin can have an optional prefix string, which is
defined by the SoC machine driver. The snd_soc_dapm_x_pin functions
take the fully-specified name including the prefix and so the existing
code would fail to find the pin if the audio machine driver had added
a prefix.
Switch to using the snd_soc_component_x_pin equivalent functions that
take a specified SoC component and automatically add the name prefix to
the provided pin name.

No dramatic changes are found in this development cycle, but as usual,
many commits are applied in a wide range of drivers.
Most of big changes are in ASoC, where a few bits of framework work
and quite a lot of cleanups and improvements to existing code have
been done. The rest are usual stuff, a few HD-audio and USB-audio
quirks and fixes, as well as the drop of kthread usages in the whole
subsystem.
Below are some highlights:
ASoC:
- Support for stereo DAPM controls
- Some initial work on the of-graph sound card
- regmap conversions of the remaining AC'97 drivers
- A new version of the topology ABI; this should be backward compatible
- Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
Intel skylake, atom-sst
- New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
Realtek RT5665
USB-audio:
- Yet another race fix at disconnection
- Tolerated packet size calculation for some Android devices
- Quirks for Axe-Fx II, QuickCam, TEAC 501/503
HD-audio:
- Improvement of Dell pin fixup mapping
- Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
Misc:
- Replace all kthread usages with simple works

The function of_get_named_gpio() could return -ENOENT, -EPROBE_DEFER
-EINVAL and so on. Currently, for the optional property "enable-gpio",
we only check -EPROBE_DEFER, this is not enough since there may be
misconfigured "enable-gpio" in the DTB, of_get_named_gpio() will return
-EINVAL in this case, we should return immediately here. And for the
optional property "gpios", we didn't check the return value, the driver
will continue to the point where gpio_request_array() is called, it
doesn't make sense to continue if we got -EPROBE_DEFER or -EINVAL here.
This patch tries to address these two issues by properly checking the
return value of of_get_named_gpio.
