From 6ed756aa0148a5ad0dbdced6f14f22e2f5748d35 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Fri, 9 Aug 2019 17:20:57 -0500 Subject: remoteproc: Add a sysfs interface for name This patch adds a sysfs interface that provides the name of the remote processor to userspace. This allows the userspace to identify a remote processor as the remoteproc devices themselves are created based on probe order and can change from one boot to another or at runtime. The name is made available in debugfs originally, and is being retained for now. This can be cleaned up after couple of releases once users get familiar with the new interface.
