fd975a7b18 gpio: menz127: Drop lock field from struct men_z127_gpio 
Current code uses a uninitialized spin lock.
bgpio_init() already initialized a spin lock, so let's switch to use
&gc->bgpio_lock instead and remove the lock from struct men_z127_gpio.

f436bc2726 gpio: add driver for MEN 16Z127 GPIO controller 
The 16Z127 is a 32bit GPIO controller on a MCB FPGA.
Every single line can be configured as input and output.

Push pull and open drain are supported as well as setting
a debounce value for the input lines.
