This is repost of
https://lore.kernel.org/linux-wireless/1539334591-9965-1-git-send-email-sgruszka@redhat.com/
with controversial patches removed. I will work on them letter.
Stanislaw Gruszka (3):
rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band
rt2800: enable TX_PIN_CFG_RFRX_EN only for MT7620
rt2800: comment and simplify AGC init for RT6352
Tomislav Požega (2):
rt2x00: remove unneeded check
rt2x00: remove confusing AGC register

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.

The TX_PIN_CFG_RFRX_EN bit was not set on other devices than MT7620,
restore old behavaviour since setting this bit maight not be
correct for older devices.

We do not need separate lines for calculating register values.
Also add comment that value is different than in vendor driver.
