* mfd: Remove gpio support from tps6586x core driverLaxman Dewangan2012-07-251-86/+21
| | | | | | | | | | | The GPIO functionality of device tps6586x is added through platform gpio driver and it can be register as the mfd sub device and hence removing the duplicates code which register the gpio functionality from core driver.

* mfd: Cache tps6586x register through regmapLaxman Dewangan2012-07-251-8/+16
| | | | | | | | | To cache the interrupt mask register, use the regmap RB_TREE cache-ing mechanism in place of implementing it locally.

* mfd: Set tps6586x bits if new value is different from the old oneAxel Lin2011-12-201-1/+1
| | | | | | | | | | It does not make sense to write new value only when all the bit_mask bits are zero. We need to write new value if the bit mask fields of new value is not equal to old value. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: Fix tps6586x GPIO value settingVincent Palatin2011-05-261-2/+2
| | | | | | | | | | | | | | In the current code, every time we set a TPS6586x GPIO pin, the tps6586x_gpio_set function is resetting all other GPIO pins. We need to update the right GPIOxOUT bit of the GPIOSET2 register instead of overriding the full value. Tested by setting sequentially GPIO2 and GPIO3 and verifying the pins voltage.

* mfd: Remove tps6586x device ID checkStephen Warren2011-01-141-7/+1
| | | | | | | | | | | | | | | ... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.

Add mfd core driver for TPS6586x PMICs family. The driver provides I/O access for the sub-device drivers and performs regstration of the sub-devices based on the platform requirements. In addition it implements GPIOlib interface for the chip GPIOs.
