mfd: palmas: Add device tree handling to mfd

2012-09-23T18:41:59+00:00

Add device tree handling to the palmas MFD. This takes the values
that can be set from platform data from the device tree nodes instead.

mfd: palmas: Add pdata/data for rest of children

2012-09-23T18:41:44+00:00

Add the platform data and data structures for children that shall be
added by a future set of commits.

mfd: palmas: Switch to linear domain in all cases

2012-09-21T21:40:37+00:00

Swith the palmas to linear domain in all cases so in future DT and non
DT cases will work the same.

With this patch children no longer need IRQ resources as it's easier
for them to use regmap_get_virq. So we can remove the resources
definitions.

mfd: palmas: Improve the error exit path

2012-09-21T21:40:36+00:00

Improve the error exit path so that we correctly de-allocate resources
that have been allocated upto the point where error occurs.

mfd: palmas: Drop kfree of devm_kzalloc's data

2012-09-17T13:03:37+00:00

Using kfree to free data allocated with devm_kzalloc causes double frees.

The semantic patch that fixes this problem is as follows:

//

expression x;

x = devm_kzalloc(...)

?-kfree(x);

mfd: core: Push irqdomain mapping out into devices

2012-09-14T07:51:54+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: Add missing hunk to change palmas irq to clear on read

2012-07-08T22:16:26+00:00

During conversion to regmap_irq this hunk was missing being moved
to MFD driver to put the chip into clear on read mode. Also as slave
is now set use it to determine which slave for the register call.

mfd: Fix palmas regulator pdata missing

2012-07-08T22:16:25+00:00

Due to a merge error the section of code passing the pdata for the
regulator driver to the mfd_add_devices via the children structure
was missing. This corrects this problem.

mfd: palmas PMIC device support

2012-05-18T15:54:47+00:00

Palmas is a PMIC from Texas Instruments and this is the MFD part of the
driver for this chip. The PMIC has SMPS and LDO regulators, a general
purpose ADC, GPIO, USB OTG mode detection, watchdog and RTC features.
