drm/vc4: Move IRQ enable to PM path

2018-02-03T16:39:17Z

[ Upstream commit ce9caf2f79a5aa170a4b6456a03db639eed9c988 ] We were calling enable_irq on bind, where it was already enabled previously by the IRQ helper. Additionally, dev->irq is not set correctly until after postinstall and so was always zero here, triggering a warning in 4.15. Fix both by moving the enable to the power management resume path, where we know there was a previous disable invocation during suspend.

drm/omap: displays: panel-dpi: add backlight dependency

drm/bridge: Fix lvds-encoder since the panel_bridge rework.

[ Upstream commit dbb58bfd9ae6c885b2ca001a9a5ab8b881fb4ba9 ] The panel_bridge bridge attaches to the panel's OF node, not the lvds-encoder's node. Put in a little no-op bridge of our own so that our consumers can still find a bridge where they expect. This also fixes an unintended unregistration and leak of the panel-bridge on module remove.
