[PATCH v8 0/6] Add HDMI jack support on RK3288

[PATCH v8 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

6fa5963c37a2 ASoC: hdmi-codec: Add an op to set callback function for plug event

has been merged to upstream.

Changes from v7 to v8:

1. rockchip_max98090: Allow three different use cases:
   max98090-only: For backward compatibility where DTS does not specify HDMI node.
   HDMI-only: For HDMI-only board like veyron-mickey.
   max98090 + HDMI: For other veyron boards.
   Pass different compatible string to specify the use case.

2. Add more maintainers to cc-list for new device property reviewing.

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
  ARM: dts: rockchip: Add HDMI audio support to rk3288-veyron-mickey.dts

[PATCH v8 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 v8 2/6] ASoC: rockchip-max98090: Support usage with and without HDMI

[Cheng-Yi Chiang]

There will be multiple boards sharing this machine driver.
Use compatible string to specify the use case.

"rockchip,rockchip-audio-max98090" for max98090-only.
"rockchip,rockchip-audio-hdmi" for HDMI-only
"rockchip,rockchip-audio-max98090-hdmi" for max98090 plus

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

The machine driver change will add support for HDMI codec in
rockchip-max98090.
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
codec DAI.

[PATCH v8 3/6] ASoC: rockchip_max98090: Optionally support HDMI use case

[Cheng-Yi Chiang]

Support three different use cases with rockchip_max98090 driver:

- 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.

Note that we keep max98090 only usage for backward compatibility.
From devicetree, different compatible string can be passed to configure
the usage.

The checkpatch error
"Macros with complex values should be enclosed in parentheses"
seems not suitable for the macro usage for DAPM widget, route, and controls.

Why not just use the presence of rockchip,hdmi-codec to enable HDMI or 
not. Maybe you still add rockchip,rockchip-audio-hdmi for HDMI only.

Really, the same should have been done for which codec is used too, but 
I guess someone wanted 2 machine drivers.

Hi Rob,
Thanks for the quick reply.
I can make change in machine driver so that
- The presence of rockchip,audio-codec enable max98090
- The presence of rockchip,hdmi-codec enable HDMI.

With that, we don't need the three properties added in this patch:
"rockchip,rockchip-audio-max98090" for max98090-only.
"rockchip,rockchip-audio-hdmi" for HDMI-only
"rockchip,rockchip-audio-max98090-hdmi" for max98090 plus HDMI.

I will post an update soon. Thanks!
