The bios interface seems messy, and it's hard to tell what the bios really wants. At first, only add support for DDI based machines (hsw+), and see how it turns out. The spec says to notify prior to power down and after power up. It is unclear whether it makes a difference. v2: - squash notification function and callers patches together (Daniel) - move callers to haswell_crtc_{enable,disable} (Daniel) - rename notification function (Chris) v3: - separate notification function and callers again, as it's not clear whether the display power state notification is the right thing to do after all v4: per Paulo's review: - drop LVDS - WARN on unsupported encoder types Signed-off-by: NJani Nikula <jani.nikula@intel.com> Reviewed-by: NPaulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>
