description:
The Broadcom Single chip MAC part for the BCM4329 family and
later Cypress chips in the same family named CYW4373 and similar.
These chips also have a Bluetooth portion described in a separate
binding.

this will be 1) or PCI device identifier.

in response to WLAN activity. This corresponds to the HOST_WAKE
line into the chip.

description: Name for the OOB IRQ, this must be set to "host-wake".

this shall be flagged as active low.

brcmfmac firmware country code and revision.
items:
pattern: '^[A-Z][A-Z]-[A-Z][0-9A-Z]-[0-9]+$'
brcm,ccode-map-trivial:
description: |
Use a trivial mapping of ISO3166 country codes to brcmfmac firmware
country code and revision: cc -> { cc, 0 }. In other words, assume that
the CLM blob firmware uses ISO3166 country codes as well, and that all
revisions are zero. This property is mutually exclusive with
brcm,ccode-map. If both properties are specified, then brcm,ccode-map
takes precedence.
type: boolean
brcm,cal-blob:
$ref: /schemas/types.yaml#/definitions/uint8-array
description: A per-device calibration blob for the Wi-Fi radio. This
should be filled in by the bootloader from platform configuration
data, if necessary, and will be uploaded to the device if present.
brcm,board-type:
$ref: /schemas/types.yaml#/definitions/string
description: Overrides the board type, which is normally the compatible of
the root node. This can be used to decouple the overall system board or
device name from the board type for WiFi purposes, which is used to
construct firmware and NVRAM configuration filenames, allowing for
multiple devices that share the same module or characteristics for the
WiFi subsystem to share the same firmware/NVRAM files. On Apple platforms,
this should be the Apple module-instance codename prefixed by "apple,",
e.g. "apple,honshu".
apple,antenna-sku:
$ref: /schemas/types.yaml#/definitions/string
description: Antenna SKU used to identify a specific antenna configuration
on Apple platforms. This is use to build firmware filenames, to allow
platforms with different antenna configs to have different firmware and/or
NVRAM. This would normally be filled in by the bootloader from platform
configuration data.
