C++ (Cpp) HW_GPIO_OUT Examples

Example #1

File: wii.c Project: AlexShiLucky/linux

static void __init wii_setup_arch(void)
{
	hw_ctrl = wii_ioremap_hw_regs("hw_ctrl", HW_CTRL_COMPATIBLE);
	hw_gpio = wii_ioremap_hw_regs("hw_gpio", HW_GPIO_COMPATIBLE);
	if (hw_gpio) {
		/* turn off the front blue led and IR light */
		clrbits32(hw_gpio + HW_GPIO_OUT(0),
			  HW_GPIO_SLOT_LED | HW_GPIO_SENSOR_BAR);
	}
}

Example #2

File: wii.c Project: karelh/liquidware_beagleboard_linux

static void wii_power_off(void)
{
	local_irq_disable();

	if (hw_gpio) {
		/* make sure that the poweroff GPIO is configured as output */
		setbits32(hw_gpio + HW_GPIO_DIR(1), HW_GPIO_SHUTDOWN);

		/* drive the poweroff GPIO high */
		setbits32(hw_gpio + HW_GPIO_OUT(1), HW_GPIO_SHUTDOWN);
	}
	wii_spin();
