[PATCH 0/5] ASoC: simple-card/audio-graph: cleanups

[Kuninori Morimoto]

Hi Mark

These patches cleanups simple-card / audio-graph.
This is part of prepare for new audio-graph-card2.

Kuninori Morimoto (5):
  ASoC: audio-graph: add graph_parse_node()
  ASoC: audio-graph: add graph_link_init()
  ASoC: simple-card: add simple_parse_node()
  ASoC: simple-card: add simple_link_init()
  ASoC: audio-graph: tidyup graph_dai_link_of_dpcm()

[PATCH 1/5] ASoC: audio-graph: add graph_parse_node()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Parse mclk_fs/dai/tdm/clk are common for both CPU/Codec node.
This patch creates graph_parse_node() for it and share the code.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
