Detailed Description

IT8300 emulator.

Function Documentation

it8300_emul_get_reg()

int it8300_emul_get_reg	(	const struct emul *	target,
		uint8_t	reg,
		uint8_t *	value )

#include <zephyr/drivers/gpio/gpio_ite_it8300_emul.h>

Read an emulated IT8300 register.

Return values

0	on success
-EINVAL	if reg is outside the emulated register map

it8300_emul_reset()

void it8300_emul_reset

(

const struct emul *

target

)

#include <zephyr/drivers/gpio/gpio_ite_it8300_emul.h>

Reset all emulated IT8300 registers.

it8300_emul_set_input()

int it8300_emul_set_input	(	const struct emul *	target,
		uint8_t	group,
		uint8_t	value )

#include <zephyr/drivers/gpio/gpio_ite_it8300_emul.h>

Set the sampled input value for one GPIO group.

Changed bits are latched in the group's interrupt status register. If alert generation is enabled, the emulated ALERT# GPIO is asserted.

Parameters

target	Emulator instance.
group	GPIO group index: 0 for A through 4 for E.
value	New sampled input value.

Return values

0	on success
-EINVAL	if group is invalid

it8300_emul_set_reg()

int it8300_emul_set_reg	(	const struct emul *	target,
		uint8_t	reg,
		uint8_t	value )

#include <zephyr/drivers/gpio/gpio_ite_it8300_emul.h>

Set an emulated IT8300 register.

This is primarily used to inject values into read-only hardware state, such as a GPIO pin data mirror register.

Return values

0	on success
-EINVAL	if reg is outside the emulated register map
