In the initial commit [1], I added differential output of the codec as separate `+` and `-` widgets:
OUTL+ OUTR+ OUTL- OUTR-
Later, in the commit [2], I added a device tree property to configure the output as single-ended or differential. Having this property, the `+` and `-` separation in widgets seems for me confusing. There are no functional benefits in such separation, so I find reasonable to get rid of it:
OUTL OUTR
The new naming is more friendly for sound cards, and is better aligned with other codec drivers in kernel.
Renaming the output widgets now should not be a problem from the backwards- compatibility perspective, as the driver for PCM3060 is added into the mainline very recently, and did not yet appear in any releases.
[1] commit 6ee47d4a8dac ("ASoC: pcm3060: Add codec driver") [2] commit a78c62de00d5 ("ASoC: pcm3060: Add DT property for single-ended output")
