Hi,everyone!

I am trying to set the pin configuration from  SPI  to the general   IO function on am335x platform with TMDSSK335X board  into  the dts file.

    acvationpin_pins_default: acvationpin_pins_default {
        pinctrl-single,pins = <
            0x158 ( PIN_OUTPUT_PULLUP | MUX_MODE7 ) /* (B16) spi0_d1.gpio0[4] */
            0x15c ( PIN_OUTPUT_PULLUP | MUX_MODE7 ) /* (A16) spi0_cs0.gpio0[5] */
        >;
    };

I use some cmd as following:

but the fact pin don't output the high level,what should i do?
