mfd: New AB8500 driver

2010-05-27T23:38:00+00:00

Add a new driver to support the AB8500 Power Management chip, replacing
the current AB4500.  The new driver replaces the old one, instead of an
incremental modification, because this is a substantial overhaul
including:

 - Split of the driver into -core and -spi portions, to allow another
   interface layer to be added

 - Addition of interrupt support

 - Switch to MFD core API for handling subdevices

 - Simplification of the APIs to remove a redundant block parameter

 - Rename of the APIs and macros from ab4500_* to ab8500_*

 - Rename of the files from ab4500* to ab8500*

 - Change of the driver name from ab4500 to ab8500

mfd: AB3100 register access change to abx500 API

2010-05-27T23:37:45+00:00

The interface for the AB3100 is changed to make way for the
ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson
Analog Baseband chips. The register access functions are moved
out to a separate struct abx500_ops. In this way the interface
is moved from the implementation and the sub functionality drivers
can keep their interface intact when chip infrastructure and
communication mechanisms changes. We also define the AB3550
device IDs and the AB3550 platform data struct and convert
the catenated 32bit event to an array of 3 x 8bits.

mfd: Renamed ab3100.h to abx500.h

2010-05-27T23:37:44+00:00

The goal here is to make way for a more general interface for the
analog baseband chips ab3100 ab3550 ab550 and future chips.

This patch have been divided into two parts since both changing name
and content of a file is not recommended in git.

mfd: Ensure WM831x charger interrupts are acknowledged when suspending

2010-05-27T23:37:39+00:00

The charger interrupts on the WM831x are unconditionally a wake source
for the system. If the power driver is not able to monitor them (for
example, due to the IRQ line not having been wired up on the system)
then any charger interrupt will prevent the system suspending for any
meaningful amount of time since nothing will ack them.

Avoid this issue by manually acknowledging these interrupts when we
suspend the WM831x core device if they are masked. If software is
actually using the interrupts then they will be unmasked and this
change will have no effect.

input: Touchscreen driver for TPS6507x

2010-05-27T23:37:38+00:00

Add touch screen input driver for TPS6507x family of multi-function
chips.  Uses the TPS6507x MFD driver.  No interrupt support due to
testing limitations of current hardware.

mfd: Add TPS6507x support

2010-05-27T23:37:38+00:00

TPS6507x are multi function (PM, touchscreen) chipsets from TI.
This commit also changes the corresponding regulator driver from being
standalone to an MFD subdevice.

mfd: Add tps6507x board data structure

2010-05-27T23:37:37+00:00

Add mfd structure which refrences sub-driver initialization data. For example,
for a giving hardware implementation, the voltage regulator sub-driver
initialization data provides the mapping betten a voltage regulator and what
the output voltage is being used for.

mfd: Move TPS6507x register definition to header file.

2010-05-27T23:37:36+00:00

Other sub-drivers for the TPS6507x chip will need to use register
definition so move it out of the source file and into a header file.
