    [ARM] 4373/1: i.MX/MX1 GPIO support implementation · b3e6a508
    Pavel Pisa authored
    Support for generic input output for MX1 family.
    The implementation prevents allocation of one pin
    by two users, but does not store pointer to the user
    description permanently, because this solution
    would have bigger memory overhead.
    
    The simple way to integrate code with per BSP
    pins setup and allocation is required else all GPIO
    registration checking is useless. The function
    imx_gpio_setup_multiple_pins() can be used for this
    purpose in future.
