[PATCH v2 0/6] DRM OF graph clean-up

[Rob Herring]

I've been unhappy with the OF graph API for some time and decided to
do something about it. The problem is drivers have to do too much of the
graph parsing and walking themselves. This has led to the same pattern
duplicated over and over. This series adds 2 new helpers and adapts DRM
drivers to use them. It only adds one new graph helper, but reduces the
use of the others which I hope to remove at some point. But we're not
there yet.

I plan to apply patch #1 to the DT tree for v4.11. The rest I will respin
for 4.12 after -rc1 to avoid any cross tree dependencies.

The build coverage should be a bit better than v1. Testing appreciated. A
git branch is here[1].

Rob Herring (6):
  of: introduce of_graph_get_remote_node
  drm: make of_drm_find_panel also depend on CONFIG_DRM_PANEL
  drm: of: introduce drm_of_find_panel_or_bridge
  drm: convert drivers to use of_graph_get_remote_node
  drm: convert drivers to use drm_of_find_panel_or_bridge
  drm: omap: use common OF graph helpers
