2025-05-21wifi: mt76: mt7915: set correct background radar capabilityStanleyYP Wang
Some of the variants do not support background radar, so add a helper to report background radar capability. For mt7916, only the variant of 5G 2T2R + 1R supports background radar.

2025-01-14wifi: mt76: mt7915: add module param to select 5 GHz or 6 GHz on MT7916Shayne Chen
Due to a limitation in available memory, the MT7916 firmware can only handle either 5 GHz or 6 GHz at a time. It does not support runtime switching without a full restart. On older firmware, this accidentally worked to some degree due to missing checks, but couldn't be supported properly, because it left the 6 GHz channels uncalibrated. Newer firmware refuses to start on either band if the passed EEPROM data indicates support for both. Deal with this limitation by using a module parameter to specify the preferred band in case both are supported.

Limit support for precal loading for mt7915 only to MTD. Passing data from DT doesn't support offset and NVMEM require a different cell name and doesn't support offset hence only MTD way is actually supported.

mt7915 does not have a per-band number of chains unlike the other chips, it only has a total number of chains. Yet the current code would consider the total number as a per-band number. For example, it would report that a 2x2 + 2x2 DBDC card have 4 chains on each band and set chainmask to 0b1111 for the first interface and 0b11110000 for the second.
