Seems very inconsistent (git log --oneline include/dt-bindings/iio/qcom,*)
but I guess this would fit better?

  dt-bindings: iio: adc: Add PM7325 PMIC7 ADC bindings

Will update for v2.

Yes, just GPL-2.0-only:
https://git.codelinaro.org/clo/la/kernel/msm-5.4/-/blob/LA.UM.9.14.1.r1-08600-QCM6490.QSSI13.0/include/dt-bindings/iio/qcom%2Cspmi-adc7-pm7325.h

Unfortunately it's the same situation with all the other header files
like this one.

  $ grep SPDX include/dt-bindings/iio/qcom,spmi-adc7-*
  include/dt-bindings/iio/qcom,spmi-adc7-pm8350.h:/* SPDX-License-Identifier: GPL-2.0-only */
  include/dt-bindings/iio/qcom,spmi-adc7-pm8350b.h:/* SPDX-License-Identifier: GPL-2.0-only */

  include/dt-bindings/iio/qcom,spmi-adc7-pmr735b.h:/* SPDX-License-Identifier: GPL-2.0-only */

If you know someone at Qualcomm to ask nicely to relicense those (plus
ones that will presumably be added later), that'd be appreciated.
