This is because the 6 GHz Max frequency supported by the driver is being compared to the Max frequency supported on the board. If in some cases, the 6 GHz Max frequency supported on the board is less than the defined 6 GHz Max frequency, all 6 GHz channels are disabled. To address this, compare the max frequency supported by the board to the defined 6 GHz Minimum frequency by the driver. Similarly, when a dual mac card supports both 6 GHz and 5 GHz radios, if the 5 GHz radio gets enumerated first before 6 GHz, the checks in ath12k_mac_setup_channels_rates() can cause the 5 GHz channels which were enabled earlier to get disabled when the 6 GHz channel list is updated. This is because the Min 6 GHz frequency defined in the driver is 5945 MHz, which should be 5925 MHz since channel 2 is not considered currently, but the firmware can pass 5925 MHz as the minimum. Hence, update the Min frequency supported by the driver to 5925 MHz. In addition, ensure that the channel list update to firmware updates only the channels that the current radio (ar) supports rather than considering the wiphy support. This would be required when multiple pdevs are supported in a wiphy and they support different ranges of frequencies or bands as in single wiphy support.
