int nmk_gpio_set_pull	(	int	gpio,
		enum nmk_gpio_pull	pull
	)

nmk_gpio_set_pull() - enable/disable pull up/down on a gpio : pin number : one of NMK_GPIO_PULL_DOWN, NMK_GPIO_PULL_UP, and NMK_GPIO_PULL_NONE

Enables/disables pull up/down on a specified pin. This only takes effect if the pin is configured as an input (either explicitly or by the alternate function).

NOTE: If enabling the pull up/down, the caller must ensure that the GPIO is configured as an input. Otherwise, due to the way the controller registers work, this function will change the value output on the pin.

Definition at line 631 of file pinctrl-nomadik.c.

int nmk_gpio_set_slpm	(	int	gpio,
		enum nmk_gpio_slpm	mode
	)

nmk_gpio_set_slpm() - configure the sleep mode of a pin : pin number : NMK_GPIO_SLPM_INPUT or NMK_GPIO_SLPM_NOCHANGE,

This register is actually in the pinmux layer, not the GPIO block itself. The GPIO1B_SLPM register defines the GPIO mode when SLEEP/DEEP-SLEEP mode is entered (i.e. when signal IOFORCE is HIGH by the platform code). Each GPIO can be configured to be forced into GPIO mode when IOFORCE is HIGH, overriding the normal setting defined by GPIO_AFSELx registers. When IOFORCE returns LOW (by software, after SLEEP/DEEP-SLEEP exit), the GPIOs return to the normal setting defined by GPIO_AFSELx registers.

If is NMK_GPIO_SLPM_INPUT, the corresponding GPIO is switched to GPIO mode when signal IOFORCE is HIGH (i.e. when SLEEP/DEEP-SLEEP mode is entered) regardless of the altfunction selected. Also wake-up detection is ENABLED.

If is NMK_GPIO_SLPM_NOCHANGE, the corresponding GPIO remains controlled by NMK_GPIO_DATC, NMK_GPIO_DATS, NMK_GPIO_DIR, NMK_GPIO_PDIS (for altfunction GPIO) or respective on-chip peripherals (for other altfuncs) when IOFORCE is HIGH. Also wake-up detection DISABLED.

Note that enable_irq_wake() will automatically enable wakeup detection.
