Subject: [PATCH 0/5] drm: dw-hdmi: update CEC phys addr, EDID and ELD on HPD event
Date: Sun, 1 Sep 2019 16:13:02 +0000 [thread overview]
Message-ID: <AM0PR06MB40049562E295DD62302C8DB7ACBF0@AM0PR06MB4004.eurprd06.prod.outlook.com> (raw)
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.
Regards,
Jonas
