4Subject: [PATCH] ath: add support for special 0x0 regulatory domain
5
6Some sdio chips of rome QCA6174's regulatory domain code of EEPROM is
7empty, then ath_is_world_regd will return false for this case, and
8it will lead function __ath_reg_dyn_country not work, thus the regdomain
9will not update for NL80211_REGDOM_SET_BY_COUNTRY_IE type, it result
10ath10k set the same regdomain/reg_5ghz_ctl/reg_2ghz_ctl to firmware,
11then the tx power will not changed with different regdomain's AP. The
12regulatory domain code of EEPROM of some QCA6174 PCIE chip is 0x6c, it
13means world wide regdomain, for this chip, it does not have the issue.
14
15For empty reulatory domain code chip, set it to world regulatory domain
16in functio ath_regd_sanitize, then it will fix the issue.
17
18Tested with QCA6174 SDIO with firmware
19WLAN.RMH.4.4.1-00029.
