[RESEND,v6,v6,1/2] ASoC: dt-bindings: qcom,wsa8840: Add reset-gpios for shared line

Commit Message

On newer Qualcomm platforms, like X1E80100-CRD, the WSA884x speakers
share SD_N GPIOs between two speakers, thus a coordinated assertion is
needed.  Linux supports handling shared GPIO lines through "reset-gpios"
property, thus allow specifying either powerdown or reset GPIOs (these
are the same).

Resending because reset part of the patchset was applied, so this can go
independently via ASoC.
