Some systems may require a different resistor than the default one (4K). This adds a property in sgtl5000 codec. It keeps the default of 4K when nothing is specified so it does not break existing code.
v2: modify the default case on DT parsing
Don't include noise like this in the changelog, add it after the --- as covered in SubmittingPatches.
+- sgtl5000-micbias-resistor : the bias resistor to be used
1 or SGTL5000_MICBIAS_2K - MICBIAS resistor is set to 2K2 or SGTL5000_MICBIAS_4K - MICBIAS resistor is set to 4K3 or SGTL5000_MICBIAS_8K - MICBIAS resistor is set to 8K0 or SGTL5000_MICBIAS_OFF - MICBIAS resistor is not used- If this node is not mentioned or if the value is unknown, then
- micbias resistor is set to 4K.
The SGTL5000_MICBIAS_* constants aren't in a DT header, so shouldn't be referenced here.
Or the constants should be moved of course but...
Why not have mcbias-resistor-k-ohms as 2, 4, 8, or 0?
That would be much easier to read as a human.
...this is even better.
