RK3288 Android7.1 PMU RK808 调试

平台：Rockchip
CPU：RK3288
PMU：RK808-B

SDIO
SDIO是在SD内存卡接口的基础上发展起来的外设接口，SDIO接口兼容以前的SD内存卡，并且可以连接SDIO接口的设备，目前根据SDIO协议的SPEC，SDIO接口支持的设备总类有蓝牙，网卡，电视卡等

SDMMC
经过我在百度上面的苦苦搜寻，关于SDMMC的总结如下：没有SDMMC卡或者是SDMMC接口，资料上出现SDMMC可能要表达的意思是SD/MMC，或者SDMMC是数字安全记忆卡（Secure Digital Memory Card）的简称，即SDMMC就是SD卡
