From f033c0bcc53675562200680f4cb4a86710d9fbae Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 1 Dec 2014 13:32:32 +0100 Subject: [PATCH 01/10] of: Decrement refcount of previous endpoint in of_graph_get_next_endpoint Decrementing the reference count of the previous endpoint node allows to use the of_graph_get_next_endpoint function in a for_each_... style macro. All current users of this function that pass a non-NULL prev parameter (that is, soc_camera and imx-drm) are changed to not decrement the passed prev argument's refcount themselves.

Although there are no guidelines currently present for how to name the dt-bindings document the "vendor,binding.txt" style is in use by some of the other vendors.
