    drivers/imx_gpio: fix usage messages · f9056d22
    Antonio Borneo authored
    The notation "(tck tms tdi tdo)* " is incorrect, because it means the
    quadruple of gpio can be repeated on the command-line.
    The correct syntax of the command requires instead to provide either
    all the four gpio numbers (in order to set the values) or to pass an
    empty command-line (to dump the values previously set).
    
    Change the .usage field to "[tck tms tdi tdo]".
    Change similarly the corresponding .usage field for SWD command.
    Add the .usage field for the commands that individually set each gpio
    or gpio property.
    Dump the previously set values when commands imx_gpio_speed_coeffs or
    imx_gpio_peripheral_base are executed with empty command-line.
