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.
