[alsa-devel] [PATCH v3 2/2] mfd: arizona: Update DT binding to support INn_MODE init_data

[Inha Song]

This patch update DT binding to support INn_MODE init_data. Each
input signal path can be configurated either as a Analogue or
Digital using the INn_MODE registers.

I would replace the second sentence here with something like
"Valid values are 0 (Differential), 1 (Single-ended) and 2 (Digital
Microphone)."

OK, I will fix it like this:

- wlf,inmode : A list of INn_MODE register values, where n is the number
  of input signals. Valid values are 0 (Differential), 1 (Single-ended) and
  2 (Digital Microphone). If absent, INn_MODE registers.........

Best regards,
Inha Song.
