This patch adds support for the ESS Sabre HiFi DAC found on some
System76 and Clevo laptops. These devices can be identified using the
Clevo subvendor id, and the Realtek ALC898 codec vendor ID. When a
connection is detected on the ESS DAC, identified by GPIO pin 2 being
set low, the 0x1b pin VREF should be set to 80%. Otherwise, it should be
set to HIZ. Testing has been performed on the current System76 line of
laptops, with and without DACs, no regressions have been found.

Please give your sign off.  Otherwise it can't be merged at all.

Looking at the changes, the changes themselves look almost good.
But the patch isn't applicable as is because of spacing or line
break.  Please fix your MUA setup or use an attachment if it really
doesn't work.

Also, last but not least, try to run checkpatch.pl and fix the
reported issues there.


thanks,

Takashi

Thanks for the patch.  But this needs more consideration,
unfortunately.

First off, the sign-off needs to have the real name.  It's a mandatory
legal matter.

And we need a proper description of the patch in the changelog.

About the code change:

Usually the mask and the direction bits are set once at initialization.

... and this whole function looks strange.  Why it's a jack detection
callback although the jack state isn't checked at all?

Is it really the jack detection on NID 0x1b?  This is no pin widget
but a mixer widget which has no such capability.

Use the proper constant.

This is no-go, will break other machines.
You can put the vendor catch-all entry in the existing table, and
check the codec IDs in the fixup function instead.

Hello there,

The patch attached below is based on Jeremy Soller's prior work on:
https://patchwork.kernel.org/patch/9552671/ , copied herein.

Cleaned up to pass checkpatch.pl tests.

I can confirm that this patch does indeed fix the audio DAC init on
the Clevo based P775TM1-R chassis with no issues.

Warm regards,

Dennis Mungai
