    rtw89: add Realtek 802.11ax driver · e3ec7017
    Ping-Ke Shih authored
    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:
