[beagleboard] Set default GPIO pin state while in sleep mode

[E Mag]

Hi,

Is there a way to set the GPIO pins into a specific state before entering 
sleep mode on the BBB? I know you can set their configuration in the device 
tree e.g.:

 wlan_pins_sleep: pinmux_wlan_pins_sleep {
                pinctrl-single,pins = <
                        0x28 (PIN_OUTPUT_PULLUP | MUX_MODE7)    /* 
gpmc_ad10.gpio0_26 WL_EN*/
                        0x2C (PIN_INPUT_PULLUP | MUX_MODE7)     /* 
gpmc_ad11.gpio0_27 WL_IRQ*/
                        0x7C (PIN_OUTPUT_PULLDOWN | MUX_MODE0)  /* 
gpmc_csn0.gpio1_29 BF_EN*/
                >;
        };

But is there a way to set a default output state for certain pins upon 
entering sleep mode without involving the PRU?

Thank you,

-Eric
