RK3568 RTL8821cs适配 WPA3连接 与 WPA3热点配置

kernel：4-19

SOC：RK3568

system：Android12

模组：RTL8821CS

调试手段可以看之前的正基AP6256

一.驱动配置：

首先设备树配置如下:

因为 SDIO 电压是1.8V，必须加上sd-uhs-sdr104;

&sdio_pwrseq{
		compatible = "mmc-pwrseq-simple";
		clocks = <&pmucru CLK_RTC_32K>;
		pinctrl-names = "default";
		pinctrl-0 = <&wifi_enable_h>;

		/*
		 * On the module itself this is one of these (depending
		 * on the actual card populated):
		 * - SDIO_RESET_L_WL_REG_ON
		 * - PDN (power down when low)
		 */
		post-power-on-delay-ms = <200>;
		reset-gpios = <&gpio0 RK_PC0 GPIO_ACTIVE_LOW>;
		status = "okay";
};

//sdio

&sdmmc1 {
	max-frequency = <150000000>;
	supports-sdio;
	bus-width = <4>;
	cap-sd-highspeed;
	cap-sdio-irq;
	keep-power-in-suspend;
	mmc-pwrseq = <&sdio_pwrseq>;
	non-removable;
	pinctrl-names = "default";
	pinctrl-0 = <&sdmmc1_bus4 &sdmmc1_cmd &sdmmc1_clk>;
	sd-uhs-sdr104;
	status = "okay";
};

rockchip_defconfig配置如下

CONFIG_WL_ROCKCHIP=y
CONFIG_WIFI_BUILD_MODULE=y
CONFIG_RTL_WIRELESS_SOLUTION=y
CONFIG_RTL8821CS=m

如果上电和sdio通路正常，SDIO会读出该模组的ID（日志如下），

[   11.206833][    T9] mmc_host mmc1: Bus speed (slot 0) = 375000Hz (slot req 400000Hz, actual 375000HZ div = 0)
[   11.226160][  T120] dwmmc_rockchip fe2c0000.dwmmc: card claims to support voltages below defined range
[   11.254622][  T120] mmc_host mmc1: Bus speed (slot 0) = 50000000Hz (slot req 100000000Hz, actual 50000000HZ div = 0)
[   11.616025][  T120] dwmmc_rockchip fe2c0000.dwmmc: Successfully tuned phase to 1
[   11.617214][  T120] mmc1: new ultra high speed SDR50 SDIO card at address 0001

然后上层去加载驱动frameworks/opt/net/wifi/libwifi_hal/rk_wifi_ctrl.cpp
