9466987f24 brcmfmac: pcie: Replace brcmf_pcie_copy_mem_todev with memcpy_toio 
The alignment check was wrong (e.g. & 4 instead of & 3), and the logic
was also inefficient if the length was not a multiple of 4, since it
would needlessly fall back to copying the entire buffer bytewise.

We already have a perfectly good memcpy_toio function, so just call that
instead of rolling our own copy logic here. brcmf_pcie_init_ringbuffers
was already using it anyway.

a21bf90e92 brcmfmac: use ISO3166 country code and 0 rev as fallback on some devices 
This is a second attempt at honering the country code send out by access
points. This was first added in commit b0b524f079 ("brcmfmac: use
ISO3166 country code and 0 rev as fallback").

Subsequently this was reverted in commit 151a7c12c4 ("Revert "brcmfmac:
use ISO3166 country code and 0 rev as fallback""), because it was causing
issues with AP mode on some brcmfmac models (specifically on BCM4359/9).

Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are
all special world-wide compatibility ccode-s. Most of these world-wide
ccode-s allow passive scan mode only for 2.4GHz channels 12-14,
only enabling them when an AP is seen on them.

But at least on brcmfmac43455 devices this is not working correctly, these
do not see accesspoints on channels 12-14 unless the ccode is changes to
a country where these channels are allowed.

Translating received country codes to an ISO3166 country code and 0 rev
ccreq fixes devices using a brcmfmac43455 with a X2/XT/XU/XV/ALL ccode
not seeing accesspoints on channels 12-14.

To avoid this causing issues on other brcmfmac models again, the
fallback is limited to only brcmfmac4345* chips this time.

db38d9cd26 rtw89: use pci_read/write_config instead of dbi read/write 
In the past we use dbi function of wifi mac to read/write
pci config space, but the function will be remove in new
chip. So use kernel api pci_read/write_config_byte instead.

good RX performance. CCK PD feature, a mechanism that adjusts 802.11b CCK
packet detection(PD) power threshold based on environment noisy level in

89e4a00ff3 rtw89: fix maybe uninitialized qempty variable 
Call to dle_dfi_qempty might fail, leaving qempty.qempty untouched, which
is latter used to control the for loop. If that happens, it's not
initialized anywhere.

Initialize it so the loop doesn't iterate unless it's modified by the
call to dle_dfi_qempty.

NL80211_BAND_* are supported. With the chipset's declaration,
we register the corresponding instances of ieee80211_supported_band
