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

80 Use a trivial mapping of ISO3166 country codes to brcmfmac firmware
81 country code and revision: cc -> { cc, 0 }. In other words, assume that
82 the CLM blob firmware uses ISO3166 country codes as well, and that all
83 revisions are zero. This property is mutually exclusive with
84 brcm,ccode-map. If both properties are specified, then brcm,ccode-map
85 takes precedence.
