* mfd: tps65912: Export OF device ID table as module aliasesJavier Martinez Canillas2017-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it. Before this patch: $ modinfo drivers/mfd/tps65912-i2c.ko | grep alias alias: i2c:tps65912 After this patch: $ modinfo drivers/mfd/tps65912-i2c.ko | grep alias alias: of:N*T*Cti,tps65912C* alias: of:N*T*Cti,tps65912 alias: i2c:tps65912 Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: tps65912: Add driver for the TPS65912 PMICAndrew F. Davis2016-02-111-0/+79
| | | | | | | | | | | | This patch adds support for TPS65912 PMIC MFD core. It provides communication through the I2C and SPI interfaces. It contains the following components: - Regulators - GPIO controller Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

* mfd: Drop owner assignment from i2c_driversKrzysztof Kozlowski2015-08-111-1/+0
| | | | | | | | i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: tps65912: Convert to managed resources for allocating memoryLee Jones2013-06-131-1/+2
| | | | | | | | Saves on code and simplifies the driver, as these resources are now tracked and freed automatically when the driver is realised. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
