mfd: sec-core: Fix possible NULL pointer dereference when i2c_new_dummy error

2014-05-06T14:55:27+00:00

commit 65aba1e04916d72b30c028730a1e31860c225412 upstream.

During probe the sec-core driver allocates dummy I2C device for RTC with
i2c_new_dummy() but return value is not checked. In case of error
(i2c_new_device(): memory allocation failure or I2C address cannot be
used) this function returns NULL which is later used by
devm_regmap_init_i2c() or i2c_unregister_device().

If i2c_new_dummy() fails for RTC device, fail also the probe for main
MFD driver.

regulator: add device tree support for s5m8767

2013-02-04T10:31:31+00:00

This device tree support is added for PMIC block of S5m8767 multi
function driver. The usage detail is added in the device tree
documentation section. This change is tested on exynos5250 based
arndale platform by regulator voltage set/get API's.

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.
