In the series, we extend the capability of mt8188-mt6359 driver.

The following changes are included. 1. Divide ADDA BE dai into two dais for SOF. 2. Register hdmi/dp jack pins. 3. dai_fmt can be configured from device tree. 4. Add some I2S codecs support.

In addition, new compatible string "mediatek,mt8188-nau8825" is included for a new board support.

Changes since v2: - unify coding style based on reviewer's suggestion - fix typo

Changes since v1: - add "Headphone Jack" for Nau8825 - separate binding patch 2 from patch 6, and rename the subject - clean up debugfs for freed widget

New subject: [PATCH v3 1/7] ASoC: mediatek: mt8188: separate ADDA playback dai from capture dai

MT8188 will support SOF. In SOF, be_hw_params_fixup callback are used to configure BE hardware parameters. However, playback and capture stream share the same callback function in which it can't know the stream type.

It's possible to require different parameters for playback and capture stream, so separate them into two dais for SOF usage.

ADDA_BE is used to connect to mt6359. For machine mt8188-mt6359, codec for ADDA_BE must be mt6359 which are configured on the machine driver. Besides, ADDA_BE is divided into two dais, UL_SRC_BE and DL_SRC_BE. As a result, remove ADDA_BE from items of link-name.

New subject: [PATCH v3 4/7] ASoC: mediatek: common: soundcard driver add dai_fmt support

There are two changes included in the patch.

First, add set_dailink_daifmt() function, so dai_fmt can be updated by the configuration in dai-link sub node.

Second, remove codec phandle from required property in dai-link sub node. For example, user possibly needs to update dai-format for all etdm co-clock dai-links, but codec doesn't need to be specified in capture dai-link for a speaker amp.

New subject: [PATCH v3 5/7] ASoC: soc-dapm.c: clean up debugfs for freed widget

When a widget is added to dapm via snd_soc_dapm_new_widgets, dapm_debugfs_add_widget is also called to create a corresponding debugfs file. However, when a widget is freed by snd_soc_dapm_free_widget, the corresponding debugfs is not cleared. As a result, the freed widget is still seen in the dapm directory.

This patch adds dapm_debugfs_free_widget to free the debugfs of a specified widget, and it's called at snd_soc_dapm_free_widget to clean up the debugfs for freed widget.

New subject: [PATCH v3 6/7] ASoC: mediatek: mt8188-mt6359: support new board with nau88255

This patch adds multiple i2s codecs support including NAU88L25, MAX98390, and the dumb amp like NAU8318 usage. In addition, dmic-codec is also added to skip the beginning pop noise.

New subject: [PATCH v3 7/7] ASoC: dt-bindings: mediatek,mt8188-mt6359: add NAU8825 support

Add compatible string "mediatek,mt8188-nau8825" to support new board with nau8825 codec.

Introduce two properties "dai-format" and "mediatek,clk-provider" under dai-link subnode to configure dai-link parameters via dts.

"codec" property is removed from required property of dai-link subnode. For co-clock case, it's possible two dai-links should be configured to the same dai format, but only one cpu dai is bound with codec.

Why is this a DT property - why not just pick one in the driver given that it's for a machine with a specific CODEC?

Hi Mark,

We aim to reuse the machine driver for various codec combinations. To achieve this, I included the property that allows overwriting of the default configuration in the machine driver.

Thanks, Trevor

In the series, we extend the capability of mt8188-mt6359 driver.

The following changes are included.

Divide ADDA BE dai into two dais for SOF.

Register hdmi/dp jack pins.

dai_fmt can be configured from device tree.

Add some I2S codecs support.

[...]

Applied to

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
