Could you please enlighten us what the status of upstreaming
ADV7511/ADV7513 support is? It is declared "work in progress" here:
http://wiki.analog.com/resources/tools-software/linux-drivers/drm/adv7511
I see some adv7511 V4L bits in drivers/media/i2c/adv7511.c, but no
drivers/gpu/drm/i2c/adv7511_{core,audio}.c as on the xcomm_zynq branch,
nor any devicetree documentation. Patchwork doesn't show any recent
submissions to LKML.
Is any major rework needed for you to get the 3.14.12 based driver upstream?
It's complicated. The plan for the driver was to wait for the common display
framework (CDF) and convert it to use CDF and then submit it upstream. The
CDF has been rejected though. Meanwhile the V4L2 adv7511 driver has been
merged. So now we are in the ugly situation that we have two different
drivers for two different frameworks. To fix this we need to merge these two
drivers while still exposing the interfaces to both frameworks.
AXI SPDIF I found in 3.16, as you noticed; what about AXI HDMI? [*]
Is there any work ongoing to get that upstream as well?
We need to teach the DMAengine framework about cyclic interleaved transfers
before the AXI HDMI driver can be submitted upstream.
