Modified Files: src/sys/arch/arm/sunxi: sunxi_gpio.c Log Message: sunxi_gpio: set interrupt debounce filter to HOSC instead of LOSC This improves gpio ISR response time from ~1.5ms to ~5us. The hardware debounce filter is of limited value anyway because if we at some point want to support interrupts from mechanical switches in gpiobutton(4) it will still need a software debounce filter to be portable to devices without hardware debouncing capability.
