Sameer Pujar May 27, 2022, 10:26 a.m. UTC 
This patch adds YAML schema for DT bindings of Output Processing
Engine (OPE) module. It consists of Parametric Equalizer (PEQ)
and Multi Band Dynamic Range Compressor (MBDRC) sub blocks and
binding doc for these blocks are added as well. The OPE will be
registered as an ASoC component and can be plugged into an audio
path as per need via ALSA mixer controls. The DT bindings are
applicable on Tegra210 and later SoCs where OPE module is present.

I did not ignore this. There was a comment from Mark on this earlier (v1) and I did not see further reply from you. I thought you were OK with the way it is. So if you are saying acronym part is OK and just to remove "Device Tree Bindings" I can send a v3 for this.

Yes, acronym is okay. Just remove the "Device Tree Bindings".
