2014-03-18mfd: sec-core: Fix possible NULL pointer dereference when i2c_new_dummy errorKrzysztof Kozlowski
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.

2014-02-26mfd: arizona: Use new regmap features for manual register patchCharles Keepax
On the wm5102 the register patches are applied manually, rather than by the regmap core. This application is wrapped in calls to regcache_cache_bypass. However, this is dangerous as other threads may be accessing the hardware at the same time as the pm_runtime operations and if they do so during the period whilst cache_bypass is enabled those writes will miss the cache when they shouldn't. Apply the register patch using the new regmap_multi_reg_write_bypassed function to avoid this problem. Also remove the call to regcache_cache_bypass from the hardware patch application as it is unneeded there and creates a similar window for writes to miss the cache.

2014-02-10ASoC: da9055: Fix device registration of PMIC and CODEC devicesAdam Thomson
Currently the I2C device Ids conflict for the MFD and CODEC so cannot be both instantiated on one platform. This patch updates the Ids and names to make them unique from each other. It should be noted that the I2C addresses for both PMIC and CODEC are modifiable so instantiation of the two are kept as separate devices, rather than instantiating the CODEC from the MFD code.

2014-01-21mfd: Always assign of_node in mfd_add_device()Stephen Warren
mfd_add_device() assigns .of_node in the device objects it creates only if the mfd_cell for the device has the .of_compatible field set and the DT node for the top-level MFD device contains a child whose compatible property matches the cell's .of_compatible field. This leaves .of_node unset in many cases. When this happens, entries in the DT /aliases property which refer to the top-level MFD DT node will never match the MFD child devices, hence causing the requested alias not to be honored. Solve this by setting each MFD child device's .of_node equal to the top- level MFD device's .of_node field in the cases where it would otherwise remain unset. The first use-case for this will be aliases for the TPS6586x's RTC device. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-01-21mfd: cros ec: spi: Add delay for raising CSRhyland Klein
The EC has specific timing it requires. Add support for an optional delay after raising CS to fix timing issues. This is configurable based on a DT property "google,cros-ec-spi-msg-delay". If this property isn't set, then no delay will be added. However, if set it will cause a delay equal to the value passed to it to be inserted at the end of a transaction.

2014-01-21mfd: cros ec: spi: Use 0 instead of '\0' consistentlyThierry Reding
memset() was being called with the second parameter set to '\0', which is equivalent but longer than the more canonical 0. Update the code to use the latter variant consistently across the driver. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-01-21mfd: cros ec: spi: Depend on OFThierry Reding
The driver is not used on any non-DT platform, so it can depend on the OF Kconfig symbol to make that explicit. This is in preparation of a subsequent patch which parses some parameters from the device tree and would otherwise have to conditionalize that code.
