Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>

ZTE ZX296702 I2S controller
|
|
|
|
Required properties:
|
|
- compatible : Must be one of:
|
|
"zte,zx296718-i2s", "zte,zx296702-i2s"
|
|
"zte,zx296702-i2s"
|
|
- reg : Must contain I2S core's registers location and length
|
|
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
|
|
- clock-names: "wclk" for the wclk, "pclk" for the pclk to the I2S interface.
|
|
- dmas: Pairs of phandle and specifier for the DMA channel that is used by
|
|
the core. The core expects two dma channels for transmit.
|
|
- dma-names : Must be "tx" and "rx"
|
|
|
|
