Hi All,
I want to control my mmc-3 clk pin which is connected with wifi.
Need to disable this pin from userspace to reduce noise.
Below is my DTS configuration :
mmc3_pins: pinmux_mmc3_pins {
pinctrl-single,pins = <
AM33XX_IOPAD(0x88C, PIN_INPUT | MUX_MODE3 | SLEWCTRL_SLOW) /* (T13) mmc2_clk */
AM33XX_IOPAD(0x888, PIN_INPUT_PULLUP | MUX_MODE3 | SLEWCTRL_SLOW) /* (V12) mmc2_cmd */
AM33XX_IOPAD(0x844, PIN_INPUT_PULLUP | MUX_MODE3 | SLEWCTRL_SLOW) /* (V14) mmc2_dat0 */
AM33XX_IOPAD(0x848, PIN_INPUT_PULLUP | MUX_MODE3 | SLEWCTRL_SLOW) /* (U14) mmc2_dat1 */
AM33XX_IOPAD(0x84C, PIN_INPUT_PULLUP | MUX_MODE3 | SLEWCTRL_SLOW) /* (T14) mmc2_dat2 */
AM33XX_IOPAD(0x878, PIN_INPUT_PULLUP | MUX_MODE3 | SLEWCTRL_SLOW) /* (U18) mmc2_dat3 */
>;
};
Is it possible to disable it from userspace? Or any possible way to disable the mmc-3 whole pins ?
Can you suggest me the possible way to do that.
