mfd: atmel-hlcdc: Add Kconfig option description and name

2014-12-01T13:03:30+00:00

The MFD_ATMEL_HLCDC was first intended to be selected by its sub-devices
but these sub-devices now depends on this option, we thus need to add
a name and a description so that users can see it.

Revert "mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption"

2014-11-25T16:18:47+00:00

This reverts commit b7cde7078d2344073c310aa65fc2b0a845d2cb5b
("mfd: sec-core: Prepare regulators for suspend state to reduce power-consumption")

Commit b7cde7078d23 called regulator_suspend_prepare() to prepare the
regulators for a suspend state. But it did from the device pm suspend
handler while the regulator suspend prepare function iterates over all
regulators and not only the one managed by this device so it doesn't
seems to be correct to call it from within a device driver.

It is better to call the regulator suspend prepare/finish functions
from platform code instead so this patch reverts the mentioned commit.

mfd: Add atmel-hlcdc driver

2014-11-25T16:18:43+00:00

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.

mfd: Add support for Diolan DLN-2 devices

2014-11-10T16:30:05+00:00

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.

mfd: axp20x: Extend axp20x to support axp288 pmic

2014-10-07T08:30:05+00:00

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.

mfd: Add support for Qualcomm SPMI PMICs

2014-09-26T07:24:00+00:00

The Qualcomm SPMI PMIC chips are components used with the
Snapdragon 800 series SoC family.  This driver exists
largely as a glue mfd component, it exists to be an owner
of an SPMI regmap for children devices described in
device tree.

mfd: Add HI6421 PMIC Core driver

2014-09-26T07:23:43+00:00

This adds driver to support HiSilicon Hi6421 PMIC. Hi6421 includes multi-
functions, such as regulators, codec, ADCs, Coulomb counter, etc.
This driver includes core APIs _only_.

Drivers for individul components, like voltage regulators, are
implemented in corresponding driver directories and files.

Registers in Hi6421 are memory mapped, so using regmap-mmio API.

mfd: RK808: Add new mfd driver for RK808

2014-09-26T07:15:56+00:00

The RK808 chip is a power management IC for multimedia and handheld
devices. It contains the following components:

- Regulators
- RTC
- Clkout

The RK808 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.
