Hello,

I could not follow your recommendations clearly, are you suggesting this:

int __init da8xx_register_pruss(struct da8xx_pruss_devices *pruss_device)
{
#ifdef CONFIG_SERIAL_PRUSS_SUART_MODULE
        int ret;

        ret = clk_add_alias(NULL, "da8xx_pruss_uart.1",
                            NULL, &da850_mcasp_device.dev);
        if (ret < 0)
                return ret;
#endif
        da8xx_pruss_dev.dev.platform_data = pruss_device;
        return platform_device_register(&da8xx_pruss_dev);
}
