Subject: [PATCH v4 0/3] Unify NVIDIA Tegra ASoC machine drivers

This series squashes all the ASoC machine drivers into a single one,
this change was suggested by Jon Hunter. It also sets driver_name and
components string of each card, allowing userspace alsa-lib to find
UCMs at predictable path.

Changelog:

v4: - Moved out mclk_rate callback that is currently used only by WM8903
      machine driver from the common driver. This was suggested by Jon Hunter.

    - Dropped patch which was setting custom components string for Nexus 7.
      Jaroslav Kysela wants it to be specified in a device-tree, but the
      components string doesn't have a firm specification for today. It's
      better to drop this change for now since it's optional anyways.

    - Fixed compilation error that was reported by kernel robot for v3.

    - Jaroslav Kysela merged alsa-ucm-conf PR [1] which added UCMs for
      Nexus 7 and Acer A500. The UCMs are fully working using a combination
      of updated kernel + alsa-ucm-conf master + alsa-lib master, meaning
      that they will work with the next releases of kernel and ALSA userspace
      upstream packages.

    - Added ack from Jaroslav Kysela to the "Specify components string for
      each card" patch that he gave to v3.

v3: - Added components string as was suggested by Jaroslav Kysela to v2.

    - Renamed MCLK rate function that is used by max98090 and other codecs
      to make it look more generic. Added option for specifying CLK ID per
      device. This all was suggested by Jon Hunter to v2.

v2: - Dropped use of of_device_compatible_match(), like it was suggested
      by Rob Herring in a review comment to v1.

    - Added patch that sets card's driver_name of as Tegra ASoC drivers.
      In a comment to v1 Jaroslav Kysela suggested that the Tegra drivers
      don't set the card name properly and he was right.

      I opened pull request with the new Tegra UCMs and updated lookup paths
      for older UCMs [1].
