SubjectApplied "ASoC: meson: axg-fifo: add fifo depth to the bindings documentation" to the asoc tree
The patch

ASoC: meson: axg-fifo: add fifo depth to the bindings documentation

has been applied to the asoc tree at for-5.6

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.

Subject: [PATCH] ASoC: meson: axg-fifo: add fifo depth to the bindings

Add a new property with the depth of the fifo in bytes. This is useful
since some instance of the fifo, even on the same SoC, may have different
depth. The depth is useful is set some parameters of the fifo.
