mfd: tps6105x: Remove linux/regulator/driver.h include

2016-05-09T07:21:11+00:00

This driver makes no use of linux/regulator/driver.h which should only
be used by drivers implementing a regulator.  Since it's unlikely to
ever need anything from there remove the include.

mfd: tps6105x: Fix possible NULL pointer access

2015-10-30T17:19:40+00:00

tps6105 driver provides two cells. One is for GPIO and another one is
for selected mode depending on platform data. When tps6105x is used in
GPIO-only mode, this driver calls mfd_add_devices() with mfd_cell
.name == NULL. This value causes an oops in platform_device_register()
later.

The following patch adds a mfd_cell for each possible mode thereby
excluding .name assignment in runtime.

mfd: tps6105x: Use i2c regmap to access registers

2015-10-05T09:38:22+00:00

This patch modifies tps6105x and associated function driver to use regmap
instead of operating directly on i2c.

mfd: tps6105x: Use managed resources when allocating memory

2014-07-25T14:31:47+00:00

This patch introduces the use of devm_kzalloc instead of the
corresponding unmanaged version and does away with the kfrees in the
probe and remove functions. Also, a label is done away with.

mfd: Use dev_get_platdata()

2013-07-31T12:01:29+00:00

Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly.

mfd: remove use of __devexit

2012-11-28T20:22:27+00:00

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

mfd: core: Push irqdomain mapping out into devices

2012-09-15T21:22:04+00:00

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

mfd: Use mfd cell platform_data for tps6105x cells platform bits

2011-05-26T17:45:11+00:00

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.
