    gpio: brcmstb: allow 0 width GPIO banks · bfba223d
    Justin Chen authored
    Sometimes we have empty banks within the GPIO block. This commit allows
    proper handling of 0 width GPIO banks. We handle 0 width GPIO banks by
    incrementing the bank and number of GPIOs, but not initializing them.
    This will mean a call into the non-existent GPIOs will return an error.
    Also remove "GPIO registered" dev print. This information is misleading
    since the incremented banks and gpio_base do not reflect the actual GPIOs
    that get initialized. We leave this information out since it is already
    printed with dev_dbg.
