This series change dw-hdmi to update CEC phys addr, EDID and ELD on HPD event, this fixes lost CEC phys addr and stale EDID/ELD when HDMI cable is unplugged/replugged or AVR is powered on/off. Patch 1 and 2 extracts code into a dw_hdmi_connector_update_edid() helper and moves dw_hdmi_connector_detect() to be able to call this helper. Patch 3 moves CEC phys addr invalidation from dw_hdmi_irq() to dw_hdmi_connector_detect() and ensure connector EDID property gets updated. I opted to not use cec_notifier_mutex after the move, please advise. Patch 4 and 5 ensures ELD gets updated allowing userspace to query the latest capabilities when a AVR is powered on and EDID gets updated. This reverts a previous change to make drm_edid_to_eld() static, please advise. Next step after this would be to add support for signaling SNDRV_CTL_EVENT_MASK_VALUE to userspace when ELD changes.
