That may be difference with standard Liunx regulatory domain settings. In this case, when .reg_notifier() called for regulatory change, mt792x chipset should update the channel usage based on clc or dts configurations. Channel would be disabled by following cases. * clc report the particular UNII-x is disabled. * dts enabled and the channel is not configured.
