From 3c827873590c3f49c76d540c1e646135a11e0b4e Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Fri, 14 Feb 2020 15:57:12 +0200 Subject: pinctrl: Use new GPIO_LINE_DIRECTION Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0. Main benefit is to make it easier to see which values mean IN and which OUT. As a side effect this helps GPIO framework to change the direction defines to something else if ever needed. Please note that return value from get_direction call on pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have returned value 2 for direction INPUT.
