[PATCH v5 0/5] Add HDMI jack support on RK3288

[Cheng-Yi Chiang]

This patch series supports HDMI jack reporting on RK3288, which uses
DRM dw-hdmi driver and hdmi-codec codec driver.

The previous discussion about reporting jack status using hdmi-notifier
and drm_audio_component is at

https://lore.kernel.org/patchwork/patch/1083027/

The new approach is to use a callback mechanism that is
specific to hdmi-codec.

Changes from v4 to v5:
- synopsys/Kconfig: Remove the incorrect dependency change in v4.
- rockchip/Kconfig: Add dependency of hdmi-codec when it is really need
  for jack support.

  drm: dw-hdmi-i2s: Use fixed id for codec device

[PATCH v5 1/5] ASoC: hdmi-codec: Add an op to set callback function for plug event

[Cheng-Yi Chiang]

Add an op in hdmi_codec_ops so codec driver can register callback
function to handle plug event.

Driver in DRM can use this callback function to report connector status.

[PATCH v5 2/5] drm: bridge: dw-hdmi: Report connector status using callback

[Cheng-Yi Chiang]

Allow codec driver register callback function for plug event.

The callback registration flow:
dw-hdmi <--- hw-hdmi-i2s-audio <--- hdmi-codec

dw-hdmi-i2s-audio implements hook_plugged_cb op
so codec driver can register the callback.

dw-hdmi exports a function dw_hdmi_set_plugged_cb so platform device
can register the callback.

When connector plug/unplug event happens, report this event using the
callback.

Make sure that audio and drm are using the single source of truth for
connector status.

[PATCH v5 3/5] drm: dw-hdmi-i2s: Use fixed id for codec device

[Cheng-Yi Chiang]

The problem of using auto ID is that the device name will be like
hdmi-audio-codec.<id number>.auto.

The number might be changed when there are other platform devices being
created before hdmi-audio-codec device.
Use a fixed name so machine driver can set codec name on the DAI link.

Using the fixed name should be fine because there will only be one
hdmi-audio-codec device.

Fix the codec name in rockchip rk3288_hdmi_analog machine driver.

[PATCH v5 4/5] ASoC: rockchip_max98090: Add dai_link for HDMI

[Cheng-Yi Chiang]

Use two dai_links. One for HDMI and one for max98090.
With this setup, audio can play to speaker and HDMI selectively.

Hi Daniel,
Do you have further concern on this patch series related to hdmi-codec
and drm part ?
We would like to merge this patch series if possible.
They will be needed in many future chrome projects for HDMI audio jack
detection.
Thanks a lot!

Hi Neil,
I am not sure if this patch series is under your radar.
Would you mind taking a look ?
This patch series has been following great suggestions from various
reviewers, so I hope it is fine now.

Audio jack reporting for HDMI might not be needed for other OS, but it
is a must on ChromeOS.
We have many previous projects using different local patch sets to
achieve HDMI jack reporting.
I hope that we can achieve a proper way and really get the patches
merged to mainline.
Thanks a lot!

I'd like some review from ASoC people and other drm bridge reviewers,
Jernej, Jonas & Andrzej.

Jonas could have some comments on the overall patchset.

Sure,
Don't forget to put Jernej, Jonas, and Jerome Brunet <jbrunet@baylibre.com> who is
working on integrating audio on the Amlogic SoCs.

The ASoC bits look basically fine, I've gone ahead and applied
patch 1 as is since we're just before the merge window and that
way we reduce potential cross tree issues.  I know there's a lot
of discussion on the DRM side about how they want to handle
things with jacks, I'm not 100% sure what the latest thinking is
there.

Thanks Mark.


Cheng-Yi can you resent this serie without the already applied
first patch with Jernej, Jonas, and Jerome Brunet <jbrunet@baylibre.com> CCed ?

Thanks,

Hi Neil,
Got it. Sorry for the late reply.
I will resend this series without the first patch, based on latest
drm-misc-next, and cc the folks.
Thanks!
