Tony, The functional changes are now merged. But let's not merge this bbb dts patch just yet, so we do not cause a conflict with the other bbb hdmi audio dts change[1] that slipped into tda998x pull request. The patch can very well wait until v4.10 if needed. However, the other three dts patches[2] can be merged. Should I rebase those on top of some branch and resend them?
