From c9fd77d48a72d4210c992c4ee27ef8217a44da03 Mon Sep 17 00:00:00 2001 From: Shinya Kuribayashi Date: Tue, 29 Oct 2013 17:57:30 +0900 Subject: [PATCH] ARM: shmobile: lager: set .debounce_interval In R-Car GPIO hardware block, 'chattering removal' feature can be enabled on GPIO-n-[3:0] pins, but it's not supported on rest of pins GPIO-n-[31:4]. Set an appropriate debounce interval, instead. We could confirm that spurious/unnecessary GPIO interrupts are prevented by this settings.
