From a32d5ce1dbf9389ad28d438dbcdaa520a913cde8 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 22 Jun 2018 00:41:25 +0200 Subject: ARM: OMAP1: ams-delta FIQ: Keep serio input GPIOs requested From the very beginning, input GPIO pins of ams-delta serio port have been used by FIQ handler, not serio driver. Don't request those pins from the ams-delta-serio driver any longer, instead keep them requested and initialized by the FIQ initialization routine which already requests them and releases while identifying GPIO IRQs.
