This driver named rtw89, which is the next generation of rtw88, supports
Realtek 8852AE 802.11ax 2x2 chip whose new features are OFDMA, DBCC,
Spatial reuse, TWT and BSS coloring; now some of them aren't implemented
though.

The chip architecture is entirely different from the chips supported by
rtw88 like RTL8822CE 802.11ac chip. First of all, register address ranges
are totally redefined, so it's impossible to reuse register definition. To
communicate with firmware, new H2C/C2H format is proposed. In order to have
better utilization, TX DMA flow is changed to two stages DMA. To provide
rich RX status information, additional RX PPDU packets are added.

Since there are so many differences mentioned above, we decide to propose
a new driver. It has many authors, they are listed in alphabetic order:

v2:
  - fix compiler warnings made by W=1
    Reported-by: kernel test robot <lkp@intel.com>
  - sort header file alphabetically
  - fix "networking block comments" reported by checkpatch

Thanks for the good introduction. Do note that currently there are two
new drivers before rtw89, so reviewing this will most likely take some
time.
