Merge series "ASoC: sun8i-codec: support for AIF2 and AIF3" from Samuel... 

Merge series "ASoC: sun8i-codec: support for AIF2 and AIF3" from Samuel Holland <samuel@sholland.org>:

This series adds support the other two AIFs present in the sun8i codec,
which can be used for codec2codec DAI links.

This series first cleans up the DAPM component driver so there is an
organized place to put the new widgets. Then it fills out the DAI
driver, removing assumptions that were made for AIF1 (16 bits, 2
channels, certain clock inversions). Some new logic is required to
handle 3 DAIs and the ADC/DAC sharing the same clock. Finally, it adds
the new DAIs, and hooks them up with DAPM widgets and routes per the
hardware topology.

To minimize the number of patches in this series, related device tree
patches (increasing #sound-dai-cells, adding new DAI links) will be sent
separately.

Samuel Holland (25):
  ASoC: sun8i-codec: Set up clock tree at probe time
