23087a0500 gpio: max77620: use the new open drain callback
The MAX77620 have a GPIO pins which can act as open drain or
push pull mode. Implement support for controlling this from GPIO
descriptor tables or other hardware descriptions such as
device tree by implementing the .set_single_ended() callback.

ff93ec7496 gpio: max77620: Configure interrupt trigger level
The GPIO sub modules of MAX77620 offers to configure the GPIO
interrupt trigger level as RISING and FALLING edge.

Pass this information to regmap-irg when registering for GPIO
interrupts.
