Merge series "ASoC: meson: tdm fixes" from Jerome Brunet <jbrunet@baylibre.com>:
This patcheset is collection of fixes for the TDM input and output the
axg audio architecture. Its fixes:
- slave mode format setting
- g12 and sm1 skew offset
- tdm clock inversion
- standard daifmt props names which don't require a specific prefix
Jerome Brunet (4):
ASoC: meson: axg-tdm-interface: fix link fmt setup
ASoC: meson: axg-tdmin: fix g12a skew
ASoC: meson: axg-tdm-formatters: fix sclk inversion
ASoC: meson: cards: remove DT_PREFIX for standard daifmt properties
