[PATCH 0/5] ASoC: mt8188: add new board support

[Trevor Wu]

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.

[PATCH 1/5] ASoC: mediatek: mt8188: separate ADDA playback dai from capture dai

[Trevor Wu]

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 paremters for playback and capture
stream, so separate them into two dais for SOF usage.

[PATCH 2/5] ASoC: mediatek: mt8188-mt6359: register hdmi/dp jack pins

[Trevor Wu]

Some userspace applications need jack control events, so register hdmi
and dp jack pins to activate jack control events.

[PATCH 3/5] ASoC: mediatek: common: soundcard driver add dai_fmt support

[Trevor Wu]

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.

[PATCH 4/5] ASoC: mediatek: mt8188-mt6359: support new board with nau88255

[Trevor Wu]

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.

[PATCH 5/5] ASoC: dt-bindings: mediatek,mt8188-mt6359: update properties

[Trevor Wu]

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

ADDA_BE is used to connect to mt6359. For the machine, it must be
fixed to the same codec and configured on the machine driver. Remove
ADDA_BE from items of link-name.

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 format, but only one dai-link builds link with codec.

hires_required is a boolean, so assigning 1 or 0 should be replaced with

This is an optional property and this function should not do anything if that
property is not found, so....

	/*
	 * Check "mediatek,clk-provider" to select the clock provider
	 * in SND_SOC_DAIFMT_CLOCK_PROVIDER_MASK area, if specified.
	 */
	if (!of_property_read_string(sub_node, "mediatek,clk-provider", &str))
		return 0;

...this allows you to reduce indentation as well.

One Intel driver using NAU8825 declares this as

		.pin	= "Headphone Jack",

can we please use the same name, so that we're able to eventually share the
same configuration in the userspace?

For reference, please check intel/avs/boards/nau8825.c

Hi Angelo,

I see jack_kctl_name_gen() will append "Jack" to the name if I don't
name the pin "HDMI Jack". Do you mean that I could directly use "HDMI
Jack" because ALSA uses the name finally?

Thanks,
Trevor

Hi Angelo,

Actually, there are two properties handled by the function.
"dai-format" is parsed at snd_soc_daifmt_parse_format(), and
"mediatek,clk-provider" is parsed by of_property_read_string().
I have to go through both properties in the function, so it can't
return directly if "mediatek,clk-provider" is not found.

Currently, this function only returns 0, but I'm not sure if it will
return a positive value for some other usage in the future.
Because a negative value is always returned for an error and the
preceding rule is also "ret < 0", I prefer "ret < 0" here. 

Thanks,
Trevor

Subject: everything can be update of properties. Rephrase to focus on

I don't understand the justification for this. If this is not a correct
link name for MT6359 setup, then it should be removed in its own patch.
If this is removed because of adding NAU8825, then why does it affect
MT6359?

You're right and I just checked; the comment even says
'remove redundant " Jack" from src_name'

So yes, the current names are fine. Sorry about that.

I checked the original commit[1] for the function. The purpose of
jack_kctl_name_gen() is to ensure only one "Jack" shown in kctrl_name.
If "Jack" is already found in src_name, don't append "Jack" again.

I'm not sure which is better for pin name, but it's certain they get
the same kctrl_name finally.

In the patch series, [PATCH 1/5] divides ADDA_BE into UL_SRC_BE and
DL_SRC_BE. I was going to replace the link name, but I found it
shouldn't be configured for the machine, because mt6359 is the only
codec for ADDA_BE and it's hardcoded in the machine driver. As a
result, I decided to remove it.

I will separate it from the patch, and put the new patch after [PATCH
1/5].
