H6 I2S is very similar to that in H3, except it supports up to 16 channels.

We are actually using a complex formula to just return a bunch of simple values. Also this formula is wrong for sun4i.

Replace this with a simpler switch case.

Also drop the i2s params not used.

From: Marcus Cooper codekipper@gmail.com

On the newer SoCs such as the H3 and A64 this is set by default to transfer a 0 after each sample in each slot. However the A10 and A20 SoCs that this driver was developed on had a default setting where it padded the audio gain with zeros.

This isn't a problem while we have only support for 16bit audio but with larger sample resolution rates in the pipeline then SEXT bits should be cleared so that they also pad at the LSB. Without this the audio gets distorted.

Set sign extend sample for all the sunxi generations even if they are not affected. This will keep consistency and avoid relying on default.

The FIFO TX reg is volatile and sun8i i2s register mapping is different from sun4i.

Even if in this case it's doesn't create an issue, Avoid setting some regs that are undefined in sun8i.

We are actually using a complex formula to just return a bunch of simple values. Also this formula is wrong for sun4i.

Just like the previous patch, this could use a bit more explanation, like why it's a good thing, or how it's wrong on sun4i

Okay I will comment a bit more.

Replace this with a simpler switch case.

Also drop the i2s params not used.

Why do we need an hex number here?

This is a register value, so I thought it's usually written using hexadecimal representation.

Also, why is the return type change needed?

This function returns a ERROR defined in errno.h which actually could be -133 but S8 only supports -128..127.

There is no real reason to have a S8 here and doesn't give any optimisation.

Yes, I agree I will check if it's really needed.

I think this was explained before. Anyway, this is needed to force width to 32, no matter actual sample width. That's a requirement of HDMI codec. I believe Marcus Cooper have another codec which also needs fixed width.

There is no similar property for I2S, so TDM one is used here.

Best regards, Jernej

Possibly, but this should be in a comment or at least the commit log

...

Anyway, this is needed to force width to 32, no matter actual sample width. That's a requirement of HDMI codec. I believe Marcus Cooper have another codec which also needs fixed width.

There is no similar property for I2S, so TDM one is used here.

Except it's really dedicated to the TDM mode and doesn't really make much sense here.

If we have special requirements like this on the codec setup, that sounds like a good justification for creating a custom codec instead of shoehorning it into simple-card

When all the remarks are fixed would it be possible to merge the rest of the series without the dts changes ?

I will propose another series to introduce a dedicated codec for that.

Yeah, sure

I was looking at sound documentation regarding how I can properly write the multi-lane I2S support. And I think we made a wrong interpretation here.

TDM slot-num and slot-width are not referencing the format called PCM or DSP_A / DSP_B. But really the physical time division representation of a format.

For example Amlogic do the following representation for Multi-lane I2S:

dai-link-7 { sound-dai = <&tdmif_b>; dai-format = "i2s"; dai-tdm-slot-tx-mask-0 = <1 1>; dai-tdm-slot-tx-mask-1 = <1 1>; dai-tdm-slot-tx-mask-2 = <1 1>; dai-tdm-slot-tx-mask-3 = <1 1>; mclk-fs = <256>;

codec {
    sound-dai = <&tohdmitx TOHDMITX_I2S_IN_B>;
};

};

So i think for 2 channels HDMI using the simple sound card with TDM property is not a hack but the correct way to represent it.

Do you agree ?

If so, can I resend the simple sound card for HDMI audio ?

I mean, it's not less weird :)

And like I said before we still have the option to write a card driver ourselves that doesn't take anything from the DT beside the phandle of the i2s controller and the HDMI controller.

If it's a fixed configuration, I'm not sure why we bother trying to make it dynamic in the DT.
