From: Shashank Sharma <shashank.sharma@xxxxxxxxx> This patch set adds 2 patches: 1. drm/i915: Optimize HDMI EDID reads This patch adds a EDID caching solution in intel_hdmi_detect function to avoid multiple EDID reads for single HPD. A delayed work function makes sure that the cached EDID gets clear after a time out. 2. drm/i915: Support for HDMI complaince HPD This patch adds support for HDMI analyzers. Most of the analyzers send a soft HPD event, where the HDMI cable removal is not required. In such scenarios, DDC is always up so EDID is always available, for both HPD up and down. So we have to rely on live status register to check the actual HPD status.
