This is a driver for the pinmux and GPIO controller available in
Amlogic Meson SoCs. At the moment it only supports Meson8 devices,
however other SoC families like Meson6 and Meson8b (the Cortex-A5
variant) appear to be similar, with just different sets of banks and
registers.
GPIO interrupts are not supported at the moment due to lack of
documentation.
