dt-bindings: net: wireless: convert marvel-8xxx.txt to yaml format
Convert binding doc marvel-8xxx.txt to yaml format. Additional change: - Remove marvell,caldata_00_txpwrlimit_2g_cfg_set in example. - Remove mmc related property in example. - Add wakeup-source property. - Remove vmmc-supply and mmc-pwrseq. Fix below warning: arch/arm64/boot/dts/freescale/imx8mp-beacon-kit.dtb: /soc@0/bus@30800000/mmc@30b40000/wifi@1: failed to match any schema with compatible: ['marvell,sd8997'] Acked-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Rob Herring (Arm) <robh@kernel.org> Signed-off-by: Frank Li <Frank.Li@nxp.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://patch.msgid.link/20240820142143.443151-1-Frank.Li@nxp.com

-Marvell 8787/8897/8978/8997 (sd8787/sd8897/sd8978/sd8997/pcie8997) SDIO/PCIE devices
-------
-
-This node provides properties for controlling the Marvell SDIO/PCIE wireless device.
-The node is expected to be specified as a child node to the SDIO/PCIE controller that
-connects the device to the system.
-
-Required properties:
-
- - compatible : should be one of the following:
- * "marvell,sd8787"
- * "marvell,sd8897"
- * "marvell,sd8978"
- * "marvell,sd8997"
- * "nxp,iw416"
- * "pci11ab,2b42"
- * "pci1b4b,2b42"
-
-Optional properties:
-
- - marvell,caldata* : A series of properties with marvell,caldata prefix,
- represent calibration data downloaded to the device during
- initialization. This is an array of unsigned 8-bit values.
- the properties should follow below property name and
- corresponding array length:
- "marvell,caldata-txpwrlimit-2g" (length = 566).
- "marvell,caldata-txpwrlimit-5g-sub0" (length = 502).
- "marvell,caldata-txpwrlimit-5g-sub1" (length = 688).
- "marvell,caldata-txpwrlimit-5g-sub2" (length = 750).
- "marvell,caldata-txpwrlimit-5g-sub3" (length = 502).
- - marvell,wakeup-pin : a wakeup pin number of wifi chip which will be configured
- to firmware. Firmware will wakeup the host using this pin
- during suspend/resume.
- - interrupts : interrupt pin number to the cpu. driver will request an irq based on
- this interrupt number. during system suspend, the irq will be enabled
- so that the wifi chip can wakeup host platform under certain condition.
- during system resume, the irq will be disabled to make sure
- unnecessary interrupt is not received.
- - vmmc-supply: a phandle of a regulator, supplying VCC to the card
- - mmc-pwrseq: phandle to the MMC power sequence node. See "mmc-pwrseq-*"
- for documentation of MMC power sequence bindings.
-
-Example:
-
-Tx power limit calibration data is configured in below example.
-The calibration data is an array of unsigned values, the length
-can vary between hw versions.
-IRQ pin 38 is used as system wakeup source interrupt. wakeup pin 3 is configured
-so that firmware can wakeup host using this device side pin.
