* apm821xx: fix bogus key-presses on bootChristian Lamparter2019-06-201-0/+30
"There are often transient line events when the system is powered up and initialized and it is often necessary for the gpio_chip driver to clear any interrupt flags in hardware before setting up the gpio chip, especially the irqchip portions of it." <http://lists.infradead.org/pipermail/openwrt-devel/2019-June/017630.html> This patch adds a fix for the APM821XX's interrupt controller to clear any bogus pending toggled interrupts that happens on various APM821XX boards on boot. The patch also changes the debouce-interval from the default 5ms debounce interval to 60ms all around. The default setting caused on occasions that the button state became stuck in a pressed state, even though the button was released. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
