C++ (Cpp) octeon_gpio_set Beispiele

Beispiel #1

Datei: gpio-octeon.c Projekt: avagin/linux

static int octeon_gpio_dir_out(struct gpio_chip *chip, unsigned offset,
			       int value)
{
	struct octeon_gpio *gpio = gpiochip_get_data(chip);
	union cvmx_gpio_bit_cfgx cfgx;

	octeon_gpio_set(chip, offset, value);

	cfgx.u64 = 0;
	cfgx.s.tx_oe = 1;

	cvmx_write_csr(gpio->register_base + bit_cfg_reg(offset), cfgx.u64);
	return 0;
