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
commit 6fa5963c37a2 ("ASoC: hdmi-codec: Add an op to set callback function for plug event")
has been merged to upstream.
Changes from v8 to v9:
1. rockchip_max98090:
Use the presence of rockchip,audio-codec to determine the presense of max98090
in sound card.
Use the presence of rockchip,hdmi-codec to determine the presence of HDMI in
sound card.
Remove the compatible strings added in v8.
2. #include <sound/hdmi-codec.h> should be in the patch of adding HDMI jack support.
Cheng-Yi Chiang (6):
drm: bridge: dw-hdmi: Report connector status using callback
ASoC: rockchip-max98090: Support usage with and without HDMI
ASoC: rockchip_max98090: Optionally support HDMI use case
ASoC: rockchip_max98090: Add HDMI jack support
ARM: dts: rockchip: Add HDMI support to rk3288-veyron-analog-audio

Add one optional property "rockchip,hdmi-codec" to let user specify HDMI
device node in DTS so machine driver can find hdmi-codec device node for
HDMI codec DAI.
Use the presence of rockchip,audio-codec and rockchip,hdmi-codec to
specify the use case.
Use max98090 only : specify rockchip,audio-codec.
Use HDMI only: specify rockchip,hdmi-codec.
Use both max98090 and HDMI: specify rockchip,audio-codec and
rockchip,hdmi-codec.
Move these properties to optional because they are not needed for
HDMI-only use case.
"rockchip,audio-codec": The phandle of the MAX98090 audio codec
"rockchip,headset-codec": The phandle of Ext chip for jack detection

2.24.0.rc0.303.g954a862665-goog
Support three different use cases with rockchip_max98090 driver.
The three use cases:
- max98090 only: Current usage, where HDMI link is missing.
- HDMI only: Needed use case for veyron_mickey board.
- max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc.
The presence of max98090 is determined by the presence of
rockchip,audio-codec device property.
The presence of HDMI is determined by the presence of
rockchip,hdmi-codec device property.
Create different sound card based on the configuration.
Note that we keep max98090 only usage for backward compatibility.

The checkpatch reported error
"Macros with complex values should be enclosed in parentheses".
It is ignored because it does not suit the usage in this patch.

- HDMI only: Needed use case for veyron_mickey board.
- max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc.
The presence of max98090 is determined by the presence of
rockchip,audio-codec device property.
The presence of HDMI is determined by the presence of
rockchip,hdmi-codec device property.
Create different sound card based on the configuration.
Note that we keep max98090 only usage for backward compatibility.

The patch
ASoC: rockchip-max98090: Support usage with and without HDMI
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,

Subject: [PATCH] ASoC: rockchip-max98090: Support usage with and without HDMI
Add one optional property "rockchip,hdmi-codec" to let user specify HDMI
device node in DTS so machine driver can find hdmi-codec device node for
HDMI codec DAI.
Use the presence of rockchip,audio-codec and rockchip,hdmi-codec to
specify the use case.
Use max98090 only : specify rockchip,audio-codec.
Use HDMI only: specify rockchip,hdmi-codec.
Use both max98090 and HDMI: specify rockchip,audio-codec and
rockchip,hdmi-codec.
Move these properties to optional because they are not needed for
HDMI-only use case.
"rockchip,audio-codec": The phandle of the MAX98090 audio codec
"rockchip,headset-codec": The phandle of Ext chip for jack detection

Mark,
This series has 6 patches. We noticed you have merged the first 4
patches (includes the DT binding one:
https://mailman.alsa-project.org/pipermail/alsa-devel/2019-October/157668.html).
There are 2 DTS patches are still on the list:
- [PATCH v9 5/6] ARM: dts: rockchip: Add HDMI support to
rk3288-veyron-analog-audio
https://mailman.alsa-project.org/pipermail/alsa-devel/2019-October/157499.html

rk3288-veyron-mickey.dts
https://mailman.alsa-project.org/pipermail/alsa-devel/2019-October/157500.html
Are you waiting for other maintainers' acknowledgement? Or do we need
to resend them with maybe some modifications?

nope all good like it is, ideally driver-changes (including the binding)
and the devicetree-changes itself go through my tree in this case, as
otherwise we would often run into conflicts if dts change go through
vastly different maintainer trees.
Of course dts changes can only get applied after the driver side is happy,
so I'll be picking up these 2 changes (hopefully shortly)
