From 7c84319af9c76084f50f3f2b97545bfa05f3971d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 17 Sep 2017 16:54:53 -0600 Subject: dm: gpio: Correct use of -ENODEV in drivers In U-Boot -ENODEV means that there is no device. When there is a problem with the device, drivers should return an error like -ENXIO or -EREMOTEIO. When the device tree properties cannot be read correct , they should return -EINVAL. Update various GPIO drivers to follow this rule, to help with consistency for future driver writers.
