int mfd_sc18is604_emul_gpio_get_output	(	const struct emul *	target,
		uint8_t	pin,
		uint8_t *	value
	)

Get the value of a GPIO output pin.

Parameters

	target	The emulated device to get the pin value from.
	pin	The pin to get the value of.
[out]	value	The value of the pin.

Returns

0 On success.

A negative error code on failure.

int mfd_sc18is604_emul_gpio_set_input	(	const struct emul *	target,
		uint8_t	pin,
		uint8_t	value
	)

Simulate a GPIO input pin being set to a specific value.

Parameters

target	The emulated device to set the pin on.
pin	The pin to set.
value	The value to set the pin to.

Returns

0 On success.

A negative error code on failure.

mfd_sc18is604_emul_i2c_get_last_tx()

int mfd_sc18is604_emul_i2c_get_last_tx	(	const struct emul *	target,
