Linus Walleij a4164863e1 Input: stmpe - enforce device tree only mode
The STMPE keypad controller is only used with device tree configured
systems, so force the configuration to come from device tree only, and now
actually get the rows and cols from the device tree too.

Linus Walleij 80e1dd82be mfd: stmpe: add pull up/down register offsets for STMPE
This adds the register offsets for pull up/down for the STMPE
1601, 1801 and 24xx expanders. This is used to bias GPIO lines
and keypad lines.

Linus Torvalds bae41e45b7 sound updates for 3.19-rc1
This became a fairly large pull request.  In addition to the usual
 driver updates / fixes, there have been a high amount of cleanups in
 ASoC area, as well as control API helpers and kernel documentations
 fixes touching through the whole tree.
 
 In the driver side, the biggest changes are the support for new Intel
 SoC found on new x86 machines, and the updates of FireWire dice and
 oxfw drivers.
 
 Some remarkable items are below:
 
 * ALSA core
  - PCM mmap code cleanup, removal of arch-dependent codes
  - PCM xrun injection support
  - PCM hwptr tracepoint support
  - Refactoring of snd_pcm_action(), simplification of PCM locking
  - Robustified sequecner auto-load functionality
  - New control API helpers and lots of cleanups along with them
  - Lots of kerneldoc fixes and cleanups
 
 * USB-audio
  - The mixer resume code was largely rewritten, and the devices with
    quirks are resumed properly.
  - New hardware support: Focusrite Scarlett, Digidesign Mbox1,
    Denon/Marantz DACs, Zoom R16/24
 
 * FireWire
  - DICE driver updates with better duplex and sync support, including
    MIDI support
  - New OXFW driver for Oxford Semiconductor FW970/971 chipset,
    including the previous LaCie Speakers device.  Fullduplex and MIDI
    support included as well as DICE driver.
 
 * HD-audio
  - Refactoring the driver-caps quirk handling in snd-hda-intel
  - More consistent control names representing the topology better
  - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic
    fix, ASUS Z99He laptop EAPD
 
 * ASoC
  - Conversion of AC'97 drivers to use regmap, bringing us closer to
    the removal of the ASoC level I/O code
  - Clean up a lot of old drivers that were open coding things that
    have subsequently been implemented in the core
  - Some DAPM performance improvements
  - Removal of the now seldom used CODEC mutex
  - Lots of updates for the newer Intel SoC support, including support
    for the DSP and some Cherrytrail and Braswell machine drivers
  - Support for Samsung boards using rt5631 as the CODEC
  - Removal of the obsolete AFEB9260 machine driver
  - Driver support for the TI TS3A227E headset driver used in some
    Chrombeooks
 
 * Others
  - ASIHPI driver update and cleanups
  - Lots of dev_*() printk conversions
  - Lots of trivial cleanups for the codes spotted by Coccinelle

Linus Torvalds f94784bdb1 regulator: Updates for v3.19
The main thing this time around is support for suspend mode
 configuration from DT which will enable some very useful power savings
 on systems where we can't rely on the bootloader configuration.  We
 still don't really support dynamic configuration of this at runtime,
 that may come later if there is any demand.
 
  - Support for specifying the target regulation mode and voltage during
    system suspend via DT, enabling power savings in that mode.
  - Reduce the default verbosity of the logging on boot, improving boot
    times especially for systems with very large numbers of regulators.
  - Lots of cleanups and fixes for Maxim PMIC drivers.
  - New driver for Richtek RT5033.

The HLCDC IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5
family or sama5d3 family) exposes 2 subdevices:
- a display controller (controlled by a DRM driver)
- a PWM chip

The MFD device provides a regmap and several clocks (those connected
to this hardware block) to its subdevices.

This way concurrent accesses to the iomem range are handled by the regmap
framework, and each subdevice can safely access HLCDC registers.

Octavian Purdila 338a128142 mfd: Add support for Diolan DLN-2 devices
This patch implements the USB part of the Diolan USB-I2C/SPI/GPIO
Master Adapter DLN-2. Details about the device can be found here:

https://www.diolan.com/i2c/i2c_interface.html.

Information about the USB protocol can be found in the Programmer's
Reference Manual [1], see section 1.7.

Because the hardware has a single transmit endpoint and a single
receive endpoint the communication between the various DLN2 drivers
and the hardware will be muxed/demuxed by this driver.

Each DLN2 module will be identified by the handle field within the DLN2
message header. If a DLN2 module issues multiple commands in parallel
they will be identified by the echo counter field in the message header.

The DLN2 modules can use the dln2_transfer() function to issue a
command and wait for its response. They can also register a callback
that is going to be called when a specific event id is generated by
the device (e.g. GPIO interrupts). The device uses handle 0 for
sending events.

Krzysztof Kozlowski c0acb8144b mfd: max77693: Fix always masked MUIC interrupts
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.

Jacob Pan af7e906954 mfd: axp20x: Extend axp20x to support axp288 pmic
X-Powers AXP288 is a customized PMIC for Intel Baytrail-CR platforms. Similar
to AXP202/209, AXP288 comes with USB charger, more LDO and BUCK channels, and
AD converters. It also provides extended status and interrupt reporting
capabilities than the devices currently supported in axp20x.c.

In addition to feature extension, this patch also adds ACPI binding for
enumeration.

This consolidated driver should support more X-Powers' PMICs in both device
tree and ACPI enumerated platforms.

Instead of having users of the ChromeOS EC call the interface-specific
cmd_xfer() callback directly, introduce a central cros_ec_cmd_xfer()
to use instead.  This will allow us to put all the locking and retry

Doug Anderson d8e0a86f97 i2c: cros_ec: Remove EC_I2C_FLAG_10BIT
In <https://lkml.org/lkml/2014/6/10/265> pointed out that the 10-bit
flag in the cros_ec_tunnel was useless.  It went into a 16-bit flags
field but was defined at (1 << 16).

Since we have no 10-bit i2c devices on the other side of the tunnel on
any known devices this was never a problem.  Until we do it makes
sense to remove this code.  On the EC side the code to handle this
flag was removed in <https://chromium-review.googlesource.com/204162>.

Mika Westerberg 6ab3430129 mfd: Add ACPI support
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.

Axel Lin e9e9d39735 mfd: da9052: Avoid setting read_flag_mask for da9052-i2c driver
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.

 - End Of Charge current,
 - Fast Charge timer,
 - Overvoltage Protection Threshold,
 - Battery Constant Voltage,
and use DTS or sysfs to configure them. This allows using the max14577 charger
driver with different batteries.

Now the charger driver requires valid configuration data from DTS. In
case of wrong configuration data it fails during probe.

The fast charge timer is configured through sysfs entry.

This patch prepares for changing the max14577 charger driver to allow
configuring battery-dependent settings from DTS.

The patch moves from regulator driver to MFD core driver and exports:
 - function for calculating register value for charger's current;
 - table of limits for chargers (MAX14577, MAX77836).

Previously they were used only by the max14577 regulator driver. In next
patch the charger driver will use them as well. Exporting them will
reduce unnecessary code duplication.
