    pinctrl-tz1090-pdc: add TZ1090 PDC pinctrl driver · b58f0273
    James Hogan authored
    Add a pin control driver for the TZ1090's low power pins via the
    powerdown controller SOC_GPIO_CONTROL registers.
    
    These pins have individually controlled pull-up, and group controlled
    schmitt, slew-rate, drive-strength, and power-on-start (pos).
    
    The pdc_gpio0 and pdc_gpio1 pins can also be muxed onto the
    ir_mod_stable_out and ir_mod_power_out functions respectively. If no
    function is set they remain in GPIO mode. These muxes can be overridden
    by requesting them as GPIOs.
