[alsa-devel] [PATCH v2 1/2] mfd: arizona: Add support for INn_Mode register control

[alsa-devel] [PATCH v2 1/2] mfd: arizona: Add support for INn_Mode register control

[Inha Song]

Some boards need to set the INn_MODE[1:0] register to change
the input signal patch. This wlf,inmode property is optional.
If present values must be specified by the number of
ARIZONA_MAX_INPUT.

Example:
   - wlf,inmode = <2 0 2 0>;	/* IN1, IN3 use DMIC */

of_property_read_u32_array with proplen as the length should be
ok here since we know the size is smaller than the inmode array.

This is going to require a DT Ack.

Is [2/2] adding the documentation?  I can't easily go and look because
you send the patch-set unthreaded.  Please thread patch-sets.  See
the man page for `git send-email` for more information.

Sorry, I will resend this patch set to use "git send email".
