2011-08-22mfd: fix tps6586x GPIO value settingPreetham Chandru
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. Also Inverted GPIO and subdevices initialization. When using a fixed voltage regulator, this allows to declare and initialize it conveniently from the "subdev" list.

... 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.
