have you got chance to test
https://github.com/psyborg55/linux/commit/24b46d482590a87553df1de0b5c8032f363cb7cf
?
using this code to determine 7620 soc
if (rt == RT5390 && rt2x00_is_soc(rt2x00dev))
rt = RT6352;
somehow did not work in rt2800_init_registers routine. i could verify
that by removing tx_sw_cfg registers from rt6352 and the wifi would
still work, unless removed them from rt5390 also
