When the EEPROM data is read from flash, it can contain pre-calibration
data, which can save calibration time.
Note that group_cal can save 30% bootup calibration time, and dpd_cal can
save 75% channel switching time.

Add testmode support for DBDC NICs (both MT7615D and MT7915D work).
Testmode data and parameters are moved from per-dev to per-phy
for maintaining the value of each band.

This can be used for calibration in the manufacturing process.
It supports sending a configurable number of packets with a specific rate
and configurable tx power levels / antenna settings.
It also supports receiving packets and showing some statistics, including
packet counters and detailed RSSI information.
It will only be compiled in if CONFIG_NL80211_TESTMODE is enabled

This subnode can be used to set per-rate tx power limits either per
country code / regdomain or globally.
These limits are typically provided by the device manufacturers and are
used to limit sideband emissions and stay within regulatory limits

mt76x0e users reported some devices (e.g TP-Link Archer VR200v) have
been flashed with big endian radio partition. Add the possibility to
specify eeprom endianness using big-endian dts property and in case
covert eeprom data in little endian

Make sure the MAC address is checked before function returns.
If CONFIG_OF is set and the device node is null, the function will
return directly, and an invalid MAC address will not be checked.

The call to of_find_node_by_phandle returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

commit d31a36b5f407d796d121af745730712337cd32a1 upstream.
There was NVMEM support added to of_get_mac_address, so it could now return
ERR_PTR encoded error values, so we need to adjust all current users of
of_get_mac_address to this new fact.
