* mfd: tps65218: Add driver for the TPS65218 PMICKeerthy2014-03-194-0/+582
| | | | | | | | | | | | | | The TPS65218 chip is a power management IC for Portable Navigation Systems and Tablet Computing devices. It contains the following components: - Regulators. - Over Temperature warning and Shut down. This patch adds support for tps65218 mfd device. At this time only the regulator functionality is made available. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: tc3589x: Reform device tree probingLinus Walleij2014-03-191-25/+59
| | | | | | | | | | | | | | | | | | | | | This changes the following mechanisms in the TC3589x device tree probing path: - Use the .of_match_table in struct device_driver to match the device in the device tree. - Add matches for the proper compatible strings "toshiba,..." and all sub-variants, just as is done for the .id matches. - Move over all the allocation of platform data etc to the tc3589x_of_probe() function and follow the pattern of passing a platform data pointer back, or an error pointer on error, as found in the STMPE driver. - Match the new (proper) compatible strings for the GPIO and keypad MFD cells. - Use of_device_is_compatible() rather than just !strcmp() to discover which cells to instantiate.

Move the main menu closing and the endif for HAS_IOMEM to the end of the file so these are selectable again.

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().
