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>

Texas Instruments DaVinci McBSP module
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
|
|
audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.
|
|
|
|
|
|
Required properties:
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
- compatible :
|
|
"ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
|
|
|
|
- reg : physical base address and length of the controller memory mapped
|
|
region(s).
|
|
- reg-names : Should contain:
|
|
* "mpu" for the main registers (required).
|
|
* "dat" for the data FIFO (optional).
|
|
|
|
- dmas: three element list of DMA controller phandles, DMA request line and
|
|
TC channel ordered triplets.
|
|
- dma-names: identifier string for each DMA request line in the dmas property.
|
|
These strings correspond 1:1 with the ordered pairs in dmas. The dma
|
|
identifiers must be "rx" and "tx".
|
|
|
|
Optional properties:
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
- interrupts : Interrupt numbers for McBSP
|
|
- interrupt-names : Known interrupt names are "rx" and "tx"
|
|
|
|
- pinctrl-0: Should specify pin control group used for this controller.
|
|
- pinctrl-names: Should contain only one value - "default", for more details
|
|
please refer to pinctrl-bindings.txt
|
|
|
|
Example (AM1808):
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
mcbsp0: mcbsp@1d10000 {
|
|
compatible = "ti,da850-mcbsp";
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&mcbsp0_pins>;
|
|
|
|
reg = <0x00110000 0x1000>,
|
|
<0x00310000 0x1000>;
|
|
reg-names = "mpu", "dat";
|
|
interrupts = <97 98>;
|
|
interrupt-names = "rx", "tx";
|
|
dmas = <&edma0 3 1
|
|
&edma0 2 1>;
|
|
dma-names = "tx", "rx";
|
|
};
