[alsa-devel] [PATCH v6 0/4] 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.
The dependent change on hdmi-codec.c
https://patchwork.kernel.org/patch/11047447
has been picked up by Mark Brown in ASoC tree for-5.4 branch.
Changes from v5 to v6:
1. Remove the patch for sound/soc/codecs/hdmi-codec.c because it is accepted. 2. Rebase the rest of patches based on drm-misc-next tree.

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.

While this is true all platforms we know of (I suppose), It might not be the case later on. I wonder if making such assumption is really desirable in a code which is used by quite a few different platforms.
Instead of trying to predict what the device name will be, can't you just query it in your machine driver ? Using a device tree phandle maybe ?
It is quite usual to set the dai links this way, "simple-card" is a good example of this.

Hi Jerome, Thanks for the quick reply! And thanks for pointing this out. I found that soc_component_to_node searches upward for one layer so it can find the node which creates hdmi-audio-codec in runtime. This works even that hdmi-audio-codec does not have its own node in dts. I will change accordingly in v7. Thanks!
