      gpio: add tps65218 gpio · c366c76a
      Nicolas Saenz Julienne authored
      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)
