[alsa-devel] [PATCH v9 0/6] Add HDMI jack support on RK3288

[alsa-devel] [PATCH v9 0/6] 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.

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.

[alsa-devel] [PATCH v9 1/6] 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 v9 1/6] 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.

[alsa-devel] Applied "drm: bridge: dw-hdmi: Report connector status using callback" to the asoc tree

[Mark Brown]

The patch

   drm: bridge: dw-hdmi: Report connector status using callback

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.

Applied "drm: bridge: dw-hdmi: Report connector status using callback" to the asoc tree

[Mark Brown]

The patch

   drm: bridge: dw-hdmi: Report connector status using callback

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,
Mark

Subject: [PATCH] drm: bridge: dw-hdmi: Report connector status using callback

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.

[alsa-devel] [PATCH v9 2/6] ASoC: rockchip-max98090: Support usage with and without HDMI

[Cheng-Yi Chiang]

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.

[alsa-devel] [PATCH v9 3/6] ASoC: rockchip_max98090: Optionally support HDMI use case

[Cheng-Yi Chiang]

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.

[PATCH v9 3/6] ASoC: rockchip_max98090: Optionally support HDMI use case

[Cheng-Yi Chiang]

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.

Signed-off-by: Cheng-Yi Chiang <cychiang@chromium.org>

 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.

[PATCH v9 3/6] ASoC: rockchip_max98090: Optionally support HDMI use case

[Cheng-Yi Chiang]

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.

[PATCH v9 3/6] ASoC: rockchip_max98090: Optionally support HDMI use case

[Cheng-Yi Chiang]

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.

Signed-off-by: Cheng-Yi Chiang <cychiang@chromium.org>
---
 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.

Subject: [PATCH] ASoC: rockchip_max98090: Optionally support HDMI use case

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.

Subject: [PATCH] ASoC: rockchip_max98090: Optionally support HDMI use case

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 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.

Subject: [PATCH] ASoC: rockchip_max98090: Optionally support HDMI use case

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.

[alsa-devel] Applied "ASoC: rockchip_max98090: Add HDMI jack support" to the asoc tree

[Mark Brown]

The patch

   ASoC: rockchip_max98090: Add HDMI jack support

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,
Mark

Applied "ASoC: rockchip_max98090: Add HDMI jack support" to the asoc tree

[Mark Brown]

The patch

   ASoC: rockchip_max98090: Add HDMI jack support

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,
Mark

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)

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)
