Your S805x2 documenation says the 4 pins above are HDMI related for func 1

I2C for those 4
It goes on like this for the rest of GPIO Bank D and I did not check the
other banks
Could you please clarify
* Does the S4 applies to S805X2, S905Y4, Both ?
* Is the S805X2 Datasheet Revision 0.4 accurate ?

On previous chip, there were pin assigned to tdm A, B or C.
On this generation, it seems you have added a second level on pinmuxing
to re-route the audio pins to different controllers
In such case, I don't think they belong in the same group.
Depending on settins, D2 and D3 could be unrelated
I think each audio pin should have its own group (one group for D3, one
D4, etc ...)

I'm curious to know what the pwm hiz function is ?

In this and all the rest similar cases leave a comma.

When it's a terminator entry, no comma is needed.

That's basically my comment above. Comment still stands
Each D and FS pin could be related to different interface and should be
in different groups
