[alsa-devel] [PATCH v5 0/5] Add HDMI jack support on RK3288
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.
Cheng-Yi Chiang (5): ASoC: hdmi-codec: Add an op to set callback function for plug event drm: bridge: dw-hdmi: Report connector status using callback drm: dw-hdmi-i2s: Use fixed id for codec device ASoC: rockchip_max98090: Add dai_link for HDMI ASoC: rockchip_max98090: Add HDMI jack support

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.

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.

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.

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!

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.
Cheng-Yi Chiang (5): ASoC: hdmi-codec: Add an op to set callback function for plug event drm: bridge: dw-hdmi: Report connector status using callback drm: dw-hdmi-i2s: Use fixed id for codec device ASoC: rockchip_max98090: Add dai_link for HDMI ASoC: rockchip_max98090: Add HDMI jack support
LGTM.

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, Neil

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!
Thanks, Neil
