解决,SDIO的设备树描述文件,缺少电源的描述 power-domains
- sdio: dwmmc@ff380000 {
- compatible = "rockchip,px30-dw-mshc", "rockchip,rk3288-dw-mshc";
- reg = <0x0 0xff380000 0x0 0x4000>;
- max-frequency = <150000000>;
- clocks = <&cru HCLK_SDIO>, <&cru SCLK_SDIO>,
- <&cru SCLK_SDIO_DRV>, <&cru SCLK_SDIO_SAMPLE>;
- clock-names = "biu", "ciu", "ciu-drv", "ciu-sample";
- assigned-clocks = <&cru SCLK_SDIO>;
- assigned-clock-parents = <&cru SCLK_SDIO_DIV50>;
- power-domains = <&power PX30_PD_MMC_NAND>;
- fifo-depth = <0x100>;
- interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
- pinctrl-names = "default";
- pinctrl-0 = <&sdio_bus4 &sdio_cmd &sdio_clk>;
