From 41f8fee385a00dcbc6107e7d356490391505a59a Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 22 Jun 2018 00:41:23 +0200 Subject: [PATCH] ARM: OMAP1: ams-delta: Hog "keybrd_dataout" GPIO pin "keybrd_dataout" GPIO pin used to be initialized by ams-delta-serio driver to a state safe for ams-delta-serio device function and not changed thereafter. As such, it may be assumed not under the driver control and responsibility for its initialization handed over to board init file. Introduce a GPIO hog table and take over control of the "keybrd_dataout" GPIO pin from the ams-delta-serio driver.
