From 813665564b3d7c74412fe2877520f1d254ce948a Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 13 Apr 2022 21:02:02 +0300 Subject: iio: core: Convert to use firmware node handle instead of OF node Switch the IIO core to use firmware node handle instead of OF node. This will allow to get label from firmware on non-OF systems. Note, this doesn't change of_iio_*() APIs for now.
