Subject: [PATCH v2 0/6] OPE support on Tegra210 and later

This series adds support for Output Prcoessing Module (OPE) module on
Tegra210 and later generations of SoCs. OPE is a client of AHUB and it
has sub blocks of PEQ (Parametric Equalizer) and MBDRC (Multi Band
Dynamic Range Compressor) for data processing.

An ASoC component is registered for OPE, which includes PEQ and MBDRC
functions as well. This can be plugged in audio path using ALSA mixer
controls. The series adds necessary binding documentaion, driver and
DT binding patches to enable OPE module on Jetson platforms.


Changelog
=========

  v1 -> v2:
  ---------
    * Use generic node names for OPE, PEQ and MBDRC devices. Update
      binding doc and DT patches for this.
    * Remove redundant nodename rule enforcement from
      OPE, PEQ and MBDRC nodes. Update binding doc patch for this.
    * Fix spaces before binding doc examples and remove '|'
      from binding doc descriptions.
