-title: Silicon Labs WFxxx devicetree bindings
-
-maintainers:
- - Jérôme Pouiller <jerome.pouiller@...abs.com>
-
-description:
- The WFxxx chip series can be connected via SPI or via SDIO.
-
- For SDIO':'
-
- The driver is able to detect a WFxxx chip on SDIO bus by matching its Vendor
- ID and Product ID. However, driver will only provide limited features in
- this case. Thus declaring WFxxx chip in device tree is recommended (and may
- become mandatory in the future).
-
- In addition, it is recommended to declare a mmc-pwrseq on SDIO host above
- WFx. Without it, you may encounter issues with warm boot. The mmc-pwrseq
- should be compatible with mmc-pwrseq-simple. Please consult
- Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.yaml for more
- information.
-
- For SPI':'
-
- In add of the properties below, please consult
- Documentation/devicetree/bindings/spi/spi-controller.yaml for optional SPI
- related properties.
-
- Note that in add of the properties below, the WFx driver also supports
- `mac-address` and `local-mac-address` as described in
- Documentation/devicetree/bindings/net/ethernet.txt
-
-properties:
- compatible:
- const: silabs,wf200
- reg:
- description:
- When used on SDIO bus, <reg> must be set to 1. When used on SPI bus, it is
- the chip select address of the device as defined in the SPI devices
- bindings.
- maxItems: 1
- spi-max-frequency:
- description: (SPI only) Maximum SPI clocking speed of device in Hz.
- maxItems: 1
- interrupts:
- description: The interrupt line. Triggers IRQ_TYPE_LEVEL_HIGH and
- IRQ_TYPE_EDGE_RISING are both supported by the chip and the driver. When
- SPI is used, this property is required. When SDIO is used, the "in-band"
- interrupt provided by the SDIO bus is used unless an interrupt is defined
- in the Device Tree.
- maxItems: 1
- reset-gpios:
- description: (SPI only) Phandle of gpio that will be used to reset chip
- during probe. Without this property, you may encounter issues with warm
- boot. (For legacy purpose, the gpio in inverted when compatible ==
- "silabs,wfx-spi")
-
- For SDIO, the reset gpio should declared using a mmc-pwrseq.
- maxItems: 1
- wakeup-gpios:
- description: Phandle of gpio that will be used to wake-up chip. Without this
- property, driver will disable most of power saving features.
- maxItems: 1
- config-file:
- description: Use an alternative file as PDS. Default is `wf200.pds`. Only
- necessary for development/debug purpose.
- maxItems: 1
-
-required:
- - compatible
- - reg
