From 529b56a854c5a8bd5e6f045cdcbbcd21a1616fbd Mon Sep 17 00:00:00 2001 From: Daniel Scally Date: Thu, 7 Jan 2021 14:28:30 +0100 Subject: [PATCH] media: device property: Define format macros for ports and endpoints OF, ACPI and software_nodes all implement graphs including nodes for ports and endpoints. These are all intended to be named with a common schema, as "port@n" and "endpoint@n" where n is an unsigned int representing the index of the node. To ensure commonality across the subsystems, provide a set of macros to define the format.
