Merge series "Support ROHM BD71815 PMIC" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:

Patch series introducing support for ROHM BD71815 PMIC

ROHM BD71815 is a power management IC used in some battery powered
systems. It contains regulators, GPO(s), charger + coulomb counter, RTC
and a clock gate.

All regulators can be controlled via I2C. LDO4 can additionally be set to
be enabled/disabled by a GPIO. LDO3 voltage could be selected from two
voltages written into separate VSEL reisters using GPIO but this mode is
not supported by driver. On top of that the PMIC has the typical HW
state machine which is present also on many other ROHM PMICs.

IC contains two GPOs - but one of the GPOs is marked as GND in
data-sheet. Thus the driver by default only exposes one GPO. The second
GPO can be enabled by special DT property.

RTC is almost similar to what is on BD71828. For currently used features
only the register address offset to RTC block differs.

The charger driver is not included in this series. ROHM has a charger
driver with some fuel-gauging logig written in but this is not included
here. I am working on separating the logic from HW specific driver and
supporting both BD71815 and BD71828 chargers in separate patch series.

Changelog v5:
Regulator:
- Added regmap helper for regulator ramp-delay and taken it in use
(patches 13, 14, 16 - they can be just dropped if ramp-delay helper is not
a good idea. Patch 15 implements old-fashioned ramp-delay)
GPIO:
- styling changes to GPIO (Mostly suggested by Andy)
- implemented init_valid_mask (but can't count on it yet)
Changelog v4:
- Sorted ROHM chip ID enum
- Statcized DVS structures in regulator driver
- Minor styling for regulator driver
- rebased on v5.12-rc4
Changelog v3:
- GPIO clean-up as suggested by Bartosz
- MFD clean-up as suggested by Lee
- clk-mode dt-binding handling in MFD driver corrected to reflect new
property values.
- Dropped already applied patches
- Rebased on v5.12-rc2
Changelog v2:
- Rebased on top of v5.11-rc3
- Added another "preliminary patch" which fixes HW-dvs voltage
handling (patch 1)
- split regulator patch to two.
- changed dt-binding patch ordering.
regulators:
- staticized probe
- removed some unnecessary defines
- updated comments
- split rohm-regulator patch adding SNVS and supporting simple
linear mapping into two - one adding support for mapping, other
adding SNVS.
GPIO:
- removed unnecessary headers
- clarified dev/parent->dev usage
- removed forgotten #define DEBUG
dt-bindings:
- changed patch order to meet ref-dependencies
- added missing regulator nodes
- changed string property for clk mode to tristated
MFD:
- header cleanups.
CLK:
- fixed commit message

Merge tag 'mute-led-rework' of https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-5.13

ALSA: control - add generic LED API

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.

A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).

The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.

The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).

snd_ctl_led 24576 0

The sound driver implementation is really easy:

1) call snd_ctl_led_request() when control LED layer should be
automatically activated
/ it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
SNDRV_CTL_ELEM_ACCESS_SPK_LED or
SNDRV_CTL_ELEM_ACCESS_MIC_LED

ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.
