From d173d0207bda8173b27a38cae439a2f904d4f7c8 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 10 Aug 2022 16:23:28 +0200 Subject: [PATCH] wifi: brcmfmac: Use ISO3166 country code and rev 0 as fallback on 43430 Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are all special world-wide compatibility ccode-s. Most of these world-wide ccode-s allow passive scan mode only for 2.4GHz channels 12-14, only enabling them when an AP is seen on them. Since linux-firmware has moved to the new cyfmac43430-sdio.bin + cyfmac43430-sdio.clm_blob firmware files this no longer works and 43430 devices using e.g. an X2 ccode fail to connect to an AP on channel 13. Add the 43430 chip-id to the list of chips for which to use the ISO3166 country code + rev 0 as fallback in brcmf_translate_country_code() to fix this.
