From b56b5528f5b3c3d47e7c0ca67318c45e980d93f0 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 4 Oct 2017 14:09:40 -0500 Subject: of: make kobject and bin_attribute support configurable Having device_nodes be kobjects is only needed if sysfs or OF_DYNAMIC is enabled. Otherwise, having a kobject in struct device_node is unnecessary bloat in minimal kernel configurations. Likewise, bin_attribute is only needed in struct property when sysfs is enabled, so we can make it configurable too.
