There are two ways through which wakeup_en register can be programmed using gpiolib APIs as shown below. It is seen that in the second case in _set_gpio_wakeup(), even though bank->suspend_wakeup is updated correctly, its value is not programmed in wakeup_en register. Fix this. chip.irq_set_type()->gpio_irq_type()->_set_gpio_triggering()->set_gpio_trigger() chip.irq_set_wake()->gpio_wake_enable()->_set_gpio_wakeup() Signed-off-by: Tarun Kanti DebBarma <tarun.kanti@xxxxxx> --- drivers/gpio/gpio-omap.c | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/drivers/gpio/gpio-omap.c b/drivers/gpio/gpio-omap.c index c9369d2..895df7f 100644 --- a/drivers/gpio/gpio-omap.c +++ b/drivers/gpio/gpio-omap.c @@ -504,6 +504,7 @@ static int _set_gpio_wakeup(struct gpio_bank *bank, int gpio, int enable) else bank->suspend_wakeup &= ~gpio_bit; + __raw_writel(bank->suspend_wakeup, bank->base + bank->regs->wkup_en); spin_unlock_irqrestore(&bank->lock, flags); return 0; -- 1.7.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
