Yakir Yang 034705a48b drm: bridge/dw_hdmi: separate VLEVCTRL settting into platform driver
Because of iMX6 & Rockchip have differnet mpll config parameter,
the VLEVCTRL parameter would be different. In this case we should
separate VLEVCTRL setting from the common dw_hdmi driver, config
this parameter in platform driver(dw_hdmi-imx and dw_hdmi-rockchip)

Ajay Kumar 3d3f8b1f8b drm/bridge: make bridge registration independent of drm flow
Currently, third party bridge drivers(ptn3460) are dependent
on the corresponding encoder driver init, since bridge driver
needs a drm_device pointer to finish drm initializations.
The encoder driver passes the drm_device pointer to the
bridge driver. Because of this dependency, third party drivers
like ptn3460 doesn't adhere to the driver model.

In this patch, we reframe the bridge registration framework
so that bridge initialization is split into 2 steps, and
bridge registration happens independent of drm flow:
--Step 1: gather all the bridge settings independent of drm and
	  add the bridge onto a global list of bridges.
--Step 2: when the encoder driver is probed, call drm_bridge_attach
	  for the corresponding bridge so that the bridge receives
	  drm_device pointer and continues with connector and other
	  drm initializations.

The old set of bridge helpers are removed, and a set of new helpers
are added to accomplish the 2 step initialization.

The bridge devices register themselves onto global list of bridges
when they get probed by calling "drm_bridge_add".

The parent encoder driver waits till the bridge is available
in the lookup table(by calling "of_drm_find_bridge") and then
continues with its initialization.

The encoder driver should also call "drm_bridge_attach" to pass
on the drm_device to the bridge object.

drm_bridge_attach inturn calls "bridge->funcs->attach" so that
bridge can continue with drm related initializations.

Andy Yan b21f4b658d drm: imx: imx-hdmi: move imx-hdmi to bridge/dw_hdmi
the original imx hdmi driver is under drm/imx/,
which depends on imx-drm, so move the imx hdmi
driver out to drm/bridge and rename it to dw_hdmi
