12description:
13 The Broadcom Single chip MAC part for the BCM4329 family and
14 later Cypress chips in the same family named CYW4373 and similar.
15 These chips also have a Bluetooth portion described in a separate
16 binding.

92 the CLM blob firmware uses ISO3166 country codes as well, and that all
93 revisions are zero. This property is mutually exclusive with
94 brcm,ccode-map. If both properties are specified, then brcm,ccode-map

107 the root node. This can be used to decouple the overall system board or
108 device name from the board type for WiFi purposes, which is used to
109 construct firmware and NVRAM configuration filenames, allowing for
110 multiple devices that share the same module or characteristics for the
111 WiFi subsystem to share the same firmware/NVRAM files. On Apple platforms,
112 this should be the Apple module-instance codename prefixed by "apple,",
113 e.g. "apple,honshu".

118 on Apple platforms. This is use to build firmware filenames, to allow
119 platforms with different antenna configs to have different firmware and/or
120 NVRAM. This would normally be filled in by the bootloader from platform
121 configuration data.
