Replace the only use of that API by the ARM Tegra sub-architecture. Signed-off-by: Stephen Warren Acked-by: Colin Cross --- This series is the irq_to_gpio patches I posted last week, rebased to ToT, plus removing Tegra's custom gpio_to_irq. This series was tested against next-20110811 on Harmony, by playing audio and plugging/unplugging headphones. Headphone detection relies on using a GPIO as an IRQ, and hence on gpio_to_irq. drivers/gpio/gpio-tegra.c | 16 ++++++++++------ 1 files changed, 10 insertions(+), 6 deletions(-) diff --git a/drivers/gpio/gpio-tegra.c b/drivers/gpio/gpio-tegra.c index 747eb40..ecade29 100644 --- a/drivers/gpio/gpio-tegra.c +++ b/drivers/gpio/gpio-tegra.c @@ -331,6 +331,7 @@ static struct lock_class_key gpio_lock_class; static int __init tegra_gpio_init(void) { struct tegra_gpio_bank *bank; + int gpio; int i; int j; @@ -352,14 +353,17 @@ static int __init tegra_gpio_init(void) gpiochip_add(&tegra_gpio_chip); - for (i = INT_GPIO_BASE; i < (INT_GPIO_BASE + TEGRA_NR_GPIOS); i++) { - bank = &tegra_gpio_banks[GPIO_BANK(irq_to_gpio(i))]; + for (gpio = 0; gpio < TEGRA_NR_GPIOS; gpio++) { + int irq = TEGRA_GPIO_TO_IRQ(gpio); + /* No validity check; all Tegra GPIOs are valid IRQs */ - irq_set_lockdep_class(i, &gpio_lock_class); - irq_set_chip_data(i, bank); - irq_set_chip_and_handler(i, &tegra_gpio_irq_chip, + bank = &tegra_gpio_banks[GPIO_BANK(gpio)]; + + irq_set_lockdep_class(irq, &gpio_lock_class); + irq_set_chip_data(irq, bank); + irq_set_chip_and_handler(irq, &tegra_gpio_irq_chip, handle_simple_irq); - set_irq_flags(i, IRQF_VALID); + set_irq_flags(irq, IRQF_VALID); } for (i = 0; i < ARRAY_SIZE(tegra_gpio_banks); i++) {
