QCLI_Command_Status_t gpio_tlmm(uint32_t Parameter_Count, QCLI_Parameter_t *Parameter_List)
{
    if (Parameter_Count < 4)
    {
        QCLI_Printf(qcli_gpio_group, "USAGE: gpio_pin fun dir pull val\n");
        QCLI_Printf(qcli_gpio_group, "\r gpio_pin -> pin number \n\r fun -> function value (0-15) \
                                      \n\r dir -> direction(input/ output) 0-input 1-output");
        QCLI_Printf(qcli_gpio_group, "\n\r pull -> gpio pull up/down/no-pull 0-No pull 1-Pull Down 2-Pull Up \
                                      \n\r val(value to drive if direction is output)");
        return QCLI_STATUS_SUCCESS_E;
    }
 
    gpio_io_handle(Parameter_Count, Parameter_List);
 
    return QCLI_STATUS_SUCCESS_E;
}
This function is defined in the GPIO demo file in QCL_demo project. Can you help me with the function value which expects a integer between 0 -15. I can't seem to find references to it nowhere in QAPI documentation or the programmer's guide. What are these functions for GPIO?

Kindly refer to Section A.13 GPIO function configuration from document QCA402x Programmer's Guide 80-Y9381-2 for GPIO function values.
