Is it correct that max732x driver will take i2c configuration from my
setup info and make each max7319 input signel into a gpio?
Hardware work correctly because without max732x driver, above i2c-dev
code can read max7319 input signel. Configuration is correct.
gpio_base is starting where max732x driver will add new gpio number
for max7319 signel.
static struct max732x_platform_data max7319_data[] = {
[0] = {
.gpio_base = NR_BUILTIN_GPIO,
},
};
static struct i2c_board_info i2c_board_info[] =
{
{
.type = "max7319",
.addr = 0x6C,
.irq = IRQ_GPIO(125), <= this is my irq pin
for max7319 INT_N
.platform_data = &max7319_data[0],
},
};
static unsigned long peony_pin_config[] __initdata = {
/* i2c bus */
GPIO105_CI2C_SDA,
GPIO106_CI2C_SCL,
} <= this correct because i2c-dev can work.
Is my understanding wrong?
