标题: rk3588:rtl8821cs:wifi mode：MMC识别SDIO 卡
MMC识别SDIO 卡失败，检查发现：我们原理图接在了sdio_m0，dts提供的板级配置接在了sdiom1_pin,没有对应的sdiom0_pin,芯片级配置如下：

sdio: mmc@fe2d0000 {
compatible = "rockchip,rk3588-dw-mshc", "rockchip,rk3288-dw-mshc";
reg = <0x0 0xfe2d0000 0x0 0x4000>;
interrupts = <GIC_SPI 204 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cru HCLK_SDIO>, <&cru CCLK_SRC_SDIO>,
<&cru SCLK_SDIO_DRV>, <&cru SCLK_SDIO_SAMPLE>;
clock-names = "biu", "ciu", "ciu-drive", "ciu-sample";
fifo-depth = <0x100>;
max-frequency = <200000000>;
pinctrl-names = "default";
pinctrl-0 = <&sdiom1_pins>;
power-domains = <&power RK3588_PD_SDIO>;
status = "disabled";
};

log如下：
[ 2.006709] dwmmc_rockchip fe2d0000.mmc: No normal pinctrl state
[ 2.006723] dwmmc_rockchip fe2d0000.mmc: No idle pinctrl state
[ 2.006857] dwmmc_rockchip fe2d0000.mmc: IDMAC supports 32-bit address mode.
[ 2.006886] dwmmc_rockchip fe2d0000.mmc: Using internal DMA controller.
[ 2.006914] dwmmc_rockchip fe2d0000.mmc: Version ID is 270a
[ 2.006966] dwmmc_rockchip fe2d0000.mmc: DW MMC controller at irq 61,32 bit host data width,256 deep fifo

请问这个如何解决，如果需要修改，这个地址是多少？，谢谢
