From e42615ec233b30dfaf117b108d4cb49455b4df1d Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Wed, 6 Nov 2019 10:54:12 +0200 Subject: gpio: Use new GPIO_LINE_DIRECTION It's hard for occasional GPIO code reader/writer to know if values 0/1 equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and GPIO_LINE_DIRECTION_OUT to help them out. NOTE - for gpio-amd-fch and gpio-bd9571mwv: This commit also changes the return value for direction get to equal 1 for direction INPUT. Prior this commit these drivers might have returned some other positive value but 1 for INPUT.
