[PATCH v4 00/22] Add Allwinner H3/H5/H6/A64 HDMI audio
Hi,
New test done by Maxime using TDM show that's LRCK is indeed inverted so I drop the patch reverted in v2.
And HDMI requires an inverted LRCK so let's readd the frame-inversion in the device-tree.
I have also added a patch to change set_chan_cfg.
Please note that I can't test TDM and only have a Allwinner H6. So test and comment on other Allwinner chips are welcome!
Regards, Clement
Change since v3: - add Samuel Holland patch to reconfigure FIFO_TX_REG when suspend is enabled - readd inversion to H6 LRCK sun50i_h6_i2s_set_soc_fmt() - Fix get_wss() for sun4i - Add a commit to fix checkpatch warning
Change since v2: - rebase on next-20200918 - drop revert LRCK polarity patch - readd simple-audio-card,frame-inversion in dts - Add patch for changing set_chan_cfg params
Change since v1: - rebase on next-20200828 - add revert LRCK polarity - remove all simple-audio-card,frame-inversion in dts - add Ondrej patches for Orange Pi board - Add arm64 defconfig patch

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

As slots and slot_width can be overwritter in case set_tdm() is called. Avoid to have this logic in set_chan_cfg().
Instead pass the required values as params to set_chan_cfg().
This also fix a bug when i2s->slot_width is set for TDM but not properly used in set_chan_cfg().

Do you mean my commit log is too short or is it a real question to understand ?
To answer if set_tdm() is called then we set the i2s->slot_width and i2s->slots. But we use lrck_period = params_physical_width(params) instead of lrck_period = i2s->slot_width ? i2s->slot_width : params_physical_width(params);
Also, Fixes tag?
I think this only happens when 20/24bit is enabled so the issue has been introduced in this series.
Clement
Thanks! Maxime

For a situation like that a note in the changelog about "in preparation for adding X support which will make this matter" helps.

Both, actually :)

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.

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.

H6 I2S is very similar to H3, except that it supports up to 16 channels and thus few registers have fields on different position.

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.

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.

It looks weird to have both some TDM setup here, and yet the format in i2s?
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 ?
Thanks, Clement

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.

Ok I see what you mean here, as the link is hardcoded in the SoC it's a better representation to hardcode it in the sound card driver than having it dynamically represented in each board device-tree.
Sounds correct for me, Thanks :)

Add a simple-soundcard to link audio between HDMI and I2S.
It makes life a lot easier if you batch all the DTS changes together rather than randomly mixing them in with code changes, it both makes it clearer what's going on and makes things easier to handle.
Now that HDMI sound node is available in the SoC dtsi. Enable it for this board.
