Register 66 was causing issues on RT6352 if set to the same value as
in MTK driver. With 1c reg value device was working fine in both HT20
and HT40 modes.

My guess is that this may change once we add proper TSSI which involes
parts of AGC init as well. I suggest to add a comment in the code to
reflect that.

We can summerize the two lines into
reg = 0x1c + (2 * rt2x00dev->lna_gain);
which is also what is was before introducing support for MT7620.

I don't understand what you suggest, could you be more specific ?

I think you mean
reg = (rf->channel <= 14 ? 0x1c : 0x24) + 2 * rt2x00dev->lna_gain;
to do not break 5GHz support for RT5592. I can change that in
separate patch, since this one in not technically wrong.
Thanks

simply add these lines:
/*

Use default value of TX_SW_CFG2 register that is in charge
of LNA timings. Works for somewhat higher RX throughput.

There is dupliceted 'if (rt2x00_rt(rt2x00dev, RT6352))' entry that couses
we do not perform proper register initaliztion for RT6352 (MT7620 SOCs).

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

I tested by adding additional printk("Init RT6352 registers\n"); in
if (rt2x00_rt(rt2x00dev, RT6352)) branch. The message was printed:

Perhaps rt2x00_is_soc(rt2x00dev) does not work on this particular system
that you have and device is configured as RT5390 ? I.e. maybe this is
PCIe device. This should be printed in :
ieee80211 phy0: rt2x00_set_rt: Info - RT chipset 6352, rev 0500 detected
line, you should have 'RT chipset 5390' instead.

RT6352 is the pre-mediatek-merge name of MT7620A/N. It is always a SoC.
The RF part of both MT7620A and MT7620N identifies as RT5390. The
vendor driver also uses an equivalent check to destinguish between the
actual PCIe/USB RT5390xx and RT6352, see
https://github.com/i80s/mtk-sources/blob/master/mt7620/src/include/rtmp_chip.h#L114

Yes , but this does not explain why things do not work as
expected for Tomislav, which IIUC use RT5390 configuration.
Perhaps the check:
if (rt == RT5390 && rt2x00_is_soc(rt2x00dev))
rt = RT6352;
should be some how modified to work on Tomislav's hardware ?

I checked 'case 2' (on my 'rt2x00' branch on top of 'openwrt-18.06'):
https://github.com/sgruszka/openwrt/commit/8abecc22605bd0221022673a3671201256cff72b
wifi still does work on my MT7620 router with above change and print
is correct.
If it does not work for you, we have to figure this out. Maybe there are
extra patches that broke things or there are some race conditions when
setting "rt =" . Hard to tell. Perhaps you could provide dmesg
from router where is does not work ?
Thanks

ok, that is strange. do you see any performance differences without
TX_SW_CFG regs? iperf test is a good pointer.
this was a problem on xiaomi mini with old DD trunk builds on 4.4
kernel and LEDE builds from last year. i ain't got no chance to try
this on 18.06. which device you tried this on? if ipa/ilna it might
make no difference

No diffrence for me. I have nexx wt3020 8M.
However I notice this set couse performance regression for me.

so this is RX test where I assume your 7265 card is sending data. is
that HT20 or HT40 mode and do you get regression on TX too?
can you try same case 2 test but with registers set to:
TX_SW_CFG0, 0x00000401
TX_SW_CFG1, 0x000C0000
TX_SW_CFG2, 0x00000000 (or 0x000C0408)
did you ever notice any tx power difference between nexx fw and openwrt fw?
