[alsa-devel] [PATCH v4 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 v3 to v4: - hdmi-codec.h: Modify the hook_plugged_cb ops to take an additional argument, that is, the pointer to struct device for codec device. - dw-hdmi-i2s-audio.c: Simplify the registration of callback so it uses dw_hdmi_set_plugged_cb exported by dw-hdmi.c. - dw-hdmi.c: Simplify the flow to invoke callback since now dw_hdmi has a pointer to codec device as callback argument. There is no need to rely on driver data of other driver. - dw-hdmi.c: Minor change for readability. - synopsys/Kconfig: Fix the dependency of hdmi-codec in Kconfig. - Fixed the incorrect FROMLIST title of patch 5/5.
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.
Change the Kconfig of DRM_DW_HDMI so it selects SND_SOC_HDMI_CODEC. This is for the typedef of hdmi_codec_plugged_cb to be used in dw-hdmi.c.

Not sure why you select SND_SOC_HDMI_CODEC in this patch. To have definition of hdmi_codec_plugged_cb, include hdmi-codec.h should be sufficient.

Thank you for the review! I misunderstood when to change Kconfig. Will fix in v5.

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.

You should not need to select the option in this patch (but in next patch), because this patch does not depend on anything from hdmi-codec.c.

Thanks for the explanation. I'll fix in v5.
In machine driver, create a jack and let hdmi-codec report jack status.

In the patch, you should select SND_SOC_HDMI_CODEC, because the patch uses hdmi_codec_set_jack_detect which depends on hdmi-codec.c.
