MT7916/mt7915e : AP is not beaconing in 6Ghz channel frequency 5975 when country code set to 'US'

[Anand-Sunkad]

When I try to bring up AP with channel 5(5975 frequency) in 6Ghz band in US country code it says channel is set to 5 but not seeing beaconing in channel 5 and also observed below error message

From the error logs it seems mt7915e driver is not able to set indoor channels 6ghz channels when country code is US
could some one help me how to resolve this issue? are there any patches available for it?
