The Texas Instruments PCM1754 is a simple stereo DAC without any digital
management interface but soft mute, PCM input format and 44.1 kHz
digital de-emphasis can be configured via strapping pins. Only soft mute
and PCM input format selection is currently exposed via optional GPIOs
in the driver.

Missing rest of patches and user of that. Maybe these are in 1/2? But
then this is misordered, see submitting patches in DT.

Keep consistent quotes

compatible is always the first. Don't use different ordering here.

Missing supply.
