[PATCH] ASoC: dt-bindings: Convert brcm,bcm2835-i2s to DT schema
Posted by Rob Herring (Arm) 1 month, 3 weeks ago
Convert the Broadcom BCM2835 I2S/PCM binding to DT schema format. It's a
straightforward conversion.

-Required properties:
-- compatible: "brcm,bcm2835-i2s"
-- reg: Should contain PCM registers location and length.
-- clocks: the (PCM) clock to use
-- dmas: List of DMA controller phandle and DMA request line ordered pairs.
-- dma-names: Identifier string for each DMA request line in the dmas property.
-  These strings correspond 1:1 with the ordered pairs in dmas.
-
-  One of the DMA channels will be responsible for transmission (should be
-  named "tx") and one for reception (should be named "rx").

-Example:
-
-bcm2835_i2s: i2s@7e203000 {

-	reg = <0x7e203000 0x24>;

Thanks!

[1/1] ASoC: dt-bindings: Convert brcm,bcm2835-i2s to DT schema
      commit: bab4ab484a6ca170847da9bffe86f1fa90df4bbe

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
