gpio: add tps65218 gpio
Driver for the GPIO block found in ti's tps65218 pmics.
The device has two GPIOs and one GPO pin which can be configured as follows:
GPIO1:
-general-purpose, open-drain output controlled by GPO1 user bit and/or
sequencer
-DDR3 reset input signal from SOC. Signal is either latched or
passed-trough to GPO2 pin. See below for details.
GPO2:
-general-purpose output controlled by GPO2 user bit
-DDR3 reset output signal. Signal is controlled by GPIO1 and PGOOD.
See below for details.
-Output buffer can be configured as open-drain or push-pull.
GPIO3:
-general-purpose, open-drain output controlled by GPO3 user bit and/or
sequencer
-reset input-signal for DCDC1 and DCDC2.
The input configurations are not meant to be used by the user so the driver
only offers GPOs.
v2: Added request routine that evaluates the fw config flags and removed module
owner
v3: Added .direction_input() routine, and took care of all Linus Walleij
suggestions (clamp to bool, use proper include)
