Hi Lars Cc Magnus, Laurent
I noticed Analog Devices has adv7511 support on http://wiki.analog.com/resources/tools-software/linux-drivers/drm/adv751 1
And I tried this driver on my board, and it works.
if my understanding was correct, latest linux kernel doesn't have adv7511 "sound" support yet. Thus, I would like to have it on linux kernel. According to this driver/file, it is under GPL-2, so it is no problem from license point of view.
According to git log Signd-off-by, Lars/Mark are listed on this adv7511 sound driver. but I wonder why it is not on upstream ? Are there some reason ?? If you don't mind, I would like to send it to ML. This is OK ?
The reason why the driver is not upstream at the moment is that the way it implements things is definitely not the right way. But there is still a lot of discussion on what actually is the right way to implement audio support for HDMI devices. Once that has been sorted out the driver will hopefully go upstream.
Beside the in-kernel API, have you given a thought to DT bindings for HDMI encoders ? Some platforms use DT bindings based on OF graph for the video path, would it make sense to model the audio path similarly ? The implementation could become a bit of a challenge though.
Thank you for explaining this background. I understand. feel free to contact me if you want me test.
