Function Documentation

void cdv_intel_lvds_init	(	struct drm_device *	dev,
		struct psb_intel_mode_device *	mode_dev
	)

cdv_intel_lvds_init - setup LVDS connectors on this device : drm device

Create the connector, register the LVDS DDC bus, and try to figure out what modes we can display on the LVDS panel (if present).

Set up I2C bus FIXME: distroy i2c_bus when exit
