[PATCH 00/10] SDM660 internal sound card support

[PATCH 00/10] SDM660 internal sound card support

[Richard Acayan]

This adds support for the SDM660 internal sound card. It is used on the
Xiaomi Redmi Note 7 for headset (playback + capture) and earpiece. It is
also used on the Google Pixel 3a for the headset.

Like MSM8916 and MSM8953, the SDM660 internal sound card connects to a
digital and analog codec. Its connection to the digital codec is through
special "internal" MI2S ports.

This series does not include devicetree patches.

[PATCH 03/10] ASoC: dt-bindings: pm8916-analog-codec: Add PM660L compatible

[Richard Acayan]

The PM8916 analog codec is also found on PM660L, typically connected to
the SDM660 internal sound card via the digital codec. Provide a space
for specific compatibles and add the compatible for PM660L.

[PATCH 10/10] ASoC: msm8916-wcd-analog: add quirk for cajon 2.0

[Richard Acayan]

The codec version CAJON_2_0 on the Snapdragon 670 requires touching the
HPH test registers. Add the quirk so this driver can also support
SDM670.

Yeah... I am pretty sure there is no such sound card. You cannot have
sound card internal to the soc, because you need the external components
like codecs.

It comes mainly from downstream driver name [1].

Downstream also mentions it as int_codec [2].

There's also an sdm660-external sndcard [3].

Downstream is antipattern, don't use it ever as argument for bindings.
It is actually very good counter argument - if downstream does something
in the bindings, then it is for sure wrong code.

It seems like "external" means "coupled with WCD934x+WSA881x" and "internal"
means "coupled with (digital cdc on SoC and analog on PMIC)-over-intI2S plus
optionally WSA881x".

I also notice some details about a WCN slimbus channel (bt and FM radio?)
in the internal one.

I ran a quick diff and they're indeed surprisingly compatible

The revision fields have changed, as well as the subtype (hmm)

Other than that, there's 2 new intr sources (boost_ocp and lo_cnp)

MICB_2_en has a new field
the TEST_CTL registers changed a little
CDC_A_NCP_FBCTRL and CDC_A_NCP_VCTRL have new fields
CDC_A_RX_COM_BIAS_DAC is slightly different (the 8916 driver doesn't
touch that part today)

CDC_A_CURRENT_LIMIT has new fields

and some undescribed-today registers have new/different fields values
otherwise it's seemingly the same


The digital part has a new rev/subtype value and some new
undescribed-today registers are added, otherwise it's the same

Interesting you left out WCD9335 (codename tasha), is it never used in
production on SDM660?

If it is used, the sound card might need to provide different
configuration (e.g. channel map) based on the codec, or we might at
least need a separate sound card driver for SDM660 with the tasha codec.

If not, a single SoC sound card driver can provide codec configuration
based on the port without checking the codec.

I also notice BTFM in the external one, on SLIMBUS_7 and SLIMBUS_8. They
don't conflict with tasha or tavil, on the other slimbus ports.

I don't know.

I think both were used with MSM8998, so I wouldn't rule that out being the
case for 660 too

internal name really looks odd.

Any reason why totally new driver without resusing the existing ones or
even the helper functions from existing code?

This comment does not make any value, Who is driving the bit clk and
frame clock is totally depended on the hw setup on the platform, Driving
incorrect clock would lead to such issues. Does the codec drive on the
platform that you are testing?

msm-4.4 lists WCD8335 in sdm660-audio.dtsi. I'd assume that's the
standard codec. On the development kits side, IFC6560 uses PM660L, while
Open-Q 660 uSOM uses WCD9335.

FWIW I think the SDM630 Sony phones use pm660l+wsa881x

I dug into the downstream Q6AFE driver a bit more. It actually inverts
the logic and specifies that the codec is a clock consumer (instead of
taking Q6AFE's perspective), so it is equivalent to setting
SND_SOC_DAIFMT_CBP_CFP.

Downstream (https://android.googlesource.com/kernel/msm-extra/+/530cffa4cc977a348753831b163eb9d3302b954a/asoc/msm-dai-q6-v2.c#4347):

	case SND_SOC_DAIFMT_CBS_CFS:
		mi2s_dai_data->rx_dai.mi2s_dai_data.port_config.i2s.ws_src = 1;
		mi2s_dai_data->tx_dai.mi2s_dai_data.port_config.i2s.ws_src = 1;
		break;

Mainline (sound/soc/qcom/q6afe.c):
	
	#define AFE_PORT_CONFIG_I2S_WS_SRC_INTERNAL	0x1
	...
	case SND_SOC_DAIFMT_BP_FP:
		pcfg->i2s_cfg.ws_src = AFE_PORT_CONFIG_I2S_WS_SRC_INTERNAL;
		break;

I don't think the downstream code needs to be explained so I would
simply drop these code comments.

Okay. If the codec needs separate configuration, the sound card driver
can just compare the codec name like in SC7180.
