mfd: Rename platform_data field of mfd_cell to mfd_data

2011-03-23T09:41:55+00:00

Rename the platform_data variable to imply a distinction between
common platform_data driver usage (typically accessed via
pdev->dev.platform_data) and the way MFD passes data down to
clients (using a wrapper named mfd_get_data).

All clients have already been changed to use the wrapper function,
so this can be a quick single-commit change that only touches things
in drivers/mfd.

mfd: mfd_cell is now implicitly available to ab3550 driver

2011-03-23T09:41:51+00:00

No clients (in mainline kernel, I'm told that drivers exist in external
trees that are planned for mainline inclusion) make use of this, nor
do they make use of platform_data, so nothing really had to change here.

The .data_size field is unused, so its usage gets removed.

mfd: Convert AB3500 to new irq_ APIs

2011-01-14T11:37:52+00:00

The genirq core is being updated to pass struct irq_data rather than irq
numbers into chip drivers. As part of the update assignments to NULL for
unused operations are removed, these are not needed and the genirq docs
should be good enough.

mfd: Staticise ab3550 register access functions

2010-08-12T09:27:22+00:00

These are now exported via an ops table rather than referenced
directly and so should be staticised.

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58+00:00

I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

mfd: AB3550 core driver

2010-05-27T23:37:46+00:00

This adds a core driver for the AB3550 mixed-signal circuit
found in the ST-Ericsson U300 platforms. This driver
is a singleton proxy for all access to the AB3550 sub
functionality drivers which can be added on top of this one:
RTC, regulators, battery and system power control, vibrator,
LEDs and an ALSA codec.
