All interrupts coming from MUIC were ignored because interrupt source
register was masked.
The Maxim 77693 has a "interrupt source" - a separate register and interrupts
which give information about PMIC block triggering the individual
interrupt (charger, topsys, MUIC, flash LED).
By default bootloader could initialize this register to "mask all"
value. In such case (observed on Trats2 board) MUIC interrupts won't be
generated regardless of their mask status. Regmap irq chip was unmasking
individual MUIC interrupts but the source was masked
Before introducing regmap irq chip this interrupt source was unmasked,
read and acked. Reading and acking is not necessary but unmasking is.

If an MFD device is backed by ACPI namespace, we should allow subdevice
drivers to access their corresponding ACPI companion devices through normal
means (e.g using ACPI_COMPANION()).
This patch adds such support to the MFD core. If the MFD parent device
does not specify any ACPI _HID/_CID for the child device, the child
device will share the parent ACPI companion device. Otherwise the child
device will be assigned with the corresponding ACPI companion, if found
in the namespace below the parent.

Current code init regmap with &da9052_regmap_config for both da9052-spi and
da9052-i2c drivers. da9052-spi sets the read_flag_mask.
The same setting may be applied for da9052-i2c if da9052-spi driver is loaded
first because they actually use the same regmap_config setting.
Fix this issue by using a local variable for regmap_config in da9052-spi driver,
so the settings in spi driver won't impact the settings in i2c driver.
Also makes da9052_regmap_config const to avoid similar issue.

This is a cleanup patch and moves min/step voltages in a common samsung
header file so that they can be used by other s2mpxxx PMIC drivers. Only
few required macros are added currently and others can be added if needed.

There've been many updates in ASoC side at this time, especially the
framework enhancement for multiple CODECs on a single DAI and more
componentization works. The only major change in ALSA core is the
addition of timestamp type in sw_params field. This should behave in
backward compatible way. Other than that, there are lots of small
changes and new drivers in wide range, including a large code cut in
HD-audio driver for deprecated static quirks. Some highlights are
below:
ALSA Core:
- Add the new timestamp type field to sw_params to choose
MONOTONIC_RAW type
HD-audio:
- Continued conversion to standard printk macros, generic code
cleanups
- Removal of obsoleted static quirk codes for Conexant and C-Media
codecs
- Fixups for HP Envy TS, Dell XPS 15, HP and Dell mute/mic LED,
Gigabyte BXBT-2807 mobo
- Intel Braswell support
ASoC:

A couple of nice new features this month, the ability to map regulators
in order to allow voltage control by external coprocessors is something
people have been asking for for a long time.
- Improved support for switch only "regulators", allowing current state
to be read from the parent regulator but no setting.
- Support for obtaining the register access method used to set
voltages, for use in systems which can offload control of this to a
coprocessor (typically for DVFS).
- Support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
TPS65917.

We only request the control interface error IRQ if we set ctrlif_error,
as such we should only free it in that situation. Otherwise we will
attempt to free an IRQ we never requested and get a warning from the IRQ
core.
This patch moves the ctrlif_error variable into the arizona structure
and checks it in all cases we free the control interface error IRQ.

If we receive EC interrupts after the cros_ec driver has probed, but
before the cros_ec_keyb driver has probed, the cros_ec IRQ handler
will not run the cros_ec_keyb notifier and the EC will leave the IRQ
line asserted. The cros_ec IRQ handler then returns IRQ_HANDLED and
the resulting flood of interrupts causes the machine to hang.
Since the EC interrupt is currently only used for the keyboard, move
the setup and handling of the EC interrupt to the cros_ec_keyb driver.
